Degree of protection

1FK7 DYA G2 motors are available with an IP64 degree of protection.

2.2.5

Noise emission

The geared motors are certified for a wide range of installation and operating conditions.

These conditions such as rigid or vibration-isolated foundation design influence noise

emission, sometimes significantly.

The circumferential velocity of the motor pinion has a significant influence on the additional

gearbox noise. This is the reason that higher speeds or low transmission ratios result in

higher noise.

Note

External noise

Noise not generated by the gearbox but emitted from it is not taken into consideration.

Noise emitted by the drive and driven machines or the base are not t

aken into consideration.

When operated in the speed range 0 to rated speed, 1FK7 DYA G2 motors can reach the

You shift the S1 characteristic curve in parallel.

At installation altitudes of 2000 m above sea level or higher, the voltage stress on the motors

must be reduced accordingly based on the "Factors for reducing the maximum DC-link

voltage" table (reciprocal values from EN 60664-1 Table A. 2).

As the DC-link voltage is reduced, the converter output voltage also decreases. This reduces

the operating range in the M-n diagram.

Operation in a vacuum is not permissible because of the low dielectric strength and poor

heat dissipation.

Determine the S1 motor characteristic when a gearbox is mounted using the following

formula:

S1gearbox = S1100K - (S1100K - S160K) / 2

The resistance change is proportional to the winding temperature change. The temperature

characteristic is taken into account in the closed-loop control.

The following diagram shows the resistance characteristic as a function of the temperature

for Pt1000 temperature sensors.

Figure 3-1 Pt1000 characteristic

The winding temperature is evaluated in the converter. When a fault occurs, an appropriate

message is output at the converter. When the motor temperature increases, a message

"Alarm motor overtemperature" is output. The message can be evaluated externally.

If this message is ignored, the converter shuts down with the appropriate fault message after

a preset time period or when the motor limiting temperature or the shutdown temperature is

exceeded.

The integrated temperature sensor protects the synchronous motors only to a certain extent

against overloads:

NOTICE

Destruction of the motor for a thermally critical load

For load applications that are critical from a thermal perspective, e.g. overload when the

motor is stationary or an overload of Mmax longer than 4 s, adequate protection is no longer

available.

• Activate the "Thermal motor model i2t monitoring" function in the converter.

The temperature sensor is part of a SELV circuit, which can be destroyed if high voltage is

applied. The temperature sensor is designed so that the DIN/EN requirement for "protective

separation" is complied with.

High short-term overload conditions require additional protective measures as a result of the

thermal coupling time of the temperature sensor.

NOTICE

Destruction of the motor for a thermal critical load

A thermally critical load, e.g. high overload when the motor is stationary, can destroy the

motor.

• Employ additional protective measures, e.g. an overcurrent relay.

Cooling

1FK7 DYA G2 is non-ventilated.

The housing surface is sufficient for dissipating heat losses where there is free convection.

Note

Dust deposits prevent heat radiation

Dust deposits prevent heat radiation and cause a high housing

temperature.

•

Keep the motor free of contamination, dust and other deposits.

The rated data of the 1FK7 DYA G2 only apply up to an ambient temperature of 40 °C

(104 °F).

To ensure sufficient cooling of the 1FK7 DYA G2, maintain a minimum clearance of 100 mm

from adjacent components on three lateral surfaces.

If the housing temperature exceeds a value of +80 °C, please contact Technical Support.

3.6

Holding brake

3.6.1

Type of holding brake

The holding brake is implemented as a permanent-magnet brake.

The magnetic field of the permanent magnets exerts a pulling force on the brake armature

disk. This means that in the no-current condition, the brake is closed and the motor shaft is

held.

When a 24 V DC rated voltage is applied to the brake, the current-carrying coil produces an

opposing field. This neutralizes the force of the permanent magnets and the brake opens

without any residual torque.

The permanent magnet brake has a torsionally stiff connection to the motor rotor. As a

consequence, the brake has no play.

NOTICE

Damage to the motor due to axial forces on the shaft extension

Axial forces on the shaft extension can damage motors with an integrated permanent-

magnet holding brake.

• Avoid axial forces on the shaft extension.

3.6.2

Properties

●The holding brake is used to clamp the motor shaft when the motor is at a standstill. The

holding brake is

not

a working brake for braking the rotating motor.

WARNING

Danger to life caused by unintended movements of the machine or installation

If you ignore the permissible number of braking operations, the braking effectiveness of

the holding brake can be irreversibly reduced. This can cause unintended movements of

the machine or installation resulting in death or serious injury.

•Observe the permissible number of braking operations.

•Operate the motor only in conjunction with an intact brake.

●The holding brake can handle 2000 braking operations as a result of Emergency Stop or

power failure without the brake being subject to inadmissible wear.

NOTICE

Premature wear of the motor holding brake when operated outside its permissible

voltage range

Operating the motor holding brake outside its permissible voltage range at the motor

connection will damage the brake.

•Ensure that the motor holding brake is only operated within its permissible voltage

range.

●The rated voltage of the holding brake is 24 VDC +/- 10%. Voltages outside this tolerance

range can cause faults.

NOTICE

Faulty brake function due to inadmissible wear

Inadmissible wear means that the braking function can no longer be guaranteed.

•Comply with the emergency stop features stated above.

•Avoid repeated brief acceleration of the motor against a holding brake that is still

closed. Consider the operating times of the brakes and the relays in the drive control

and enable.

Note

Subsequent conversion of motors with or without a holding brake is not possible.

Safety instructions

WARNING

Electric shock and danger to life due to other energy sources

Touching live components can result in death or severe injury.

•Only work on electrical devices when you are qualified for this job.

•Always observe the country-specific safety rules.

Generally, the following six steps apply when establishing safety:

1. Prepare for disconnection. Notify all those who will be affected by the procedure.

2. Isolate the drive system from the power supply and take measures to prevent it being

switched back on again.

3. Wait until the discharge time specified on the warning labels has elapsed.

4. Check that there is no voltage between any of the power connections, and between any

of the power connections and the protective conductor connection.

5. Check whether the existing auxiliary supply circuits are de-energized.

6. Ensure that the motors cannot move.

7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or

water. Switch the energy sources to a safe state.

8. Check that the correct drive system is completely locked.

After you have completed the work, restore the operational readiness in the inverse

sequence.

WARNING

Electric shock when connected to inadequately grounded line supplies

Connecting a motor to an inadequately grounded line supply can result in death, severe

injury and damage to the motor if a fault occurs.

•Connect motors, as part of the drive system, to TN and TT line supplies with a grounded

neutral point or to IT line supplies.

•Ensure that the SINAMICS devices and motors are compatible with the residual current

device according to EN 61800-5-1 before you connect the devices and motors to the

line supply using residual current devices (RCDs).

•For line supplies with grounded line conductor, e.g. TT line supplies, use an isolating

transformer with grounded neutral point (on the secondary side) between the line supply

and the drive system, so that the motor insulation is not overstressed.

•When connected to IT line supplies, a monitoring device must signal the first fault

between an active part and ground. Eliminate this fault immediately.

Connecting

6.2 Permissible line systems

S-1FK7 DYA G2 synchronous motors with planetary gearbox

56 Operating Instructions, 05/2018, A5E44881183B AA

6.2

Permissible line systems

In combination with the drive system, the motors are generally approved for operation on TN

and TT systems with

grounded neutral

and on IT systems.

In operation on IT systems, the occurrence of a first fault between an active part and ground

must be signaled by a monitoring device. According to IEC 60364-4-41, it is recommended

that the first fault is removed as quickly as is practically possible.

In systems with a

grounded external conductor

, an isolating transformer with grounded

neutral (secondary side) must be connected between the line supply and the drive system to

protect the motor insulation from excessive stress. The majority of TT systems have a

grounded external conductor, so in this case an isolating transformer must be used.

Connecting the holding brake

Direct connection

The holding brake in the motor is directly connected to the SINAMICS converter using

MOTION-CONNECT power cables with integrated brake connecting cable. See Chapter

"Connecting to a converter (Page 62)"

Connection to external power supply

You can also control the holding brake via an external power supply.

The external power supply can be a PELV (PELV = Protective Extra Low Voltage) power

supply, if:

●Protective separation from the motor winding is guaranteed for the brake cable in the

motor

●The power cable has reinforced insulation

Note

The relay K1, located between coil and contact, must also have reinforced insulation to

protect the internal logic voltage.

If you control the holding brake via an external power supply, you must protect the holding

brake from voltage peaks with a protective circuit. See figure "Suggested circuit for the

external power supply"

The protective circuit also guarantees the specified switching times, see Chapter "Holding

brake (Page 39)".

The motor holding brake requires 24 V ± 10 % at the motor connection in order to reliably

open.

●Take into account the voltage drops along the supply cable.

●Use a Control Supply Module (CSM) or a regulated DC power supply, whose setpoint is

set to 26 V.

●Use power supply cables with a minimum cross-section of 1.5 mm².

●Calculate the maximum permissible cable length using the following formula.

If the maximum voltage of 24 V DC +10 % is exceeded, then the brake can close again.

You can approximately calculate the voltage drop Δ

for copper cables as follows:

/ V = 0.042 •

10.2.4

Bearing replacement interval

The bearings are subject to wear and must be replaced after a defined number of operating

hours.

For average load levels, the bearings must be replaced after approx. 25,000 hours.

Bearing replacement intervals can be extended if the motor is operated under favorable

conditions, e.g. low average speeds, low radial forces (cantilever forces), vibration load.

Note

Harsh operating conditions

If the motor is subject to harsh operating conditions (e.g. continuous operation at n

max, high

vibration/shock loads, frequent reversing duty etc.), the bearing replacement intervals t

can decrease by up to 50%.

Safety instructions

Removing the motor from the machine

WARNING

Electric shock when live parts are touched

Death or serious injury can result when live parts are touched.

•Only work on electrical equipment if you are appropriately qualified.

•Always comply with the local national safety regulations when working on electrical

equipment.

Generally, six steps apply when establishing safety:

1. Prepare for shutdown and notify all those who will be affected by the procedure.

2. Disconnect the machine from the power supply.

–Switch off the machine.

–Wait until the discharge time specified on the warning labels has elapsed.

–Check that it really de-energized, from phase to phase and phase to protective

conductor.

–Check that every auxiliary circuit is de-energized.

–Ensure that the motors cannot move.

3. Secure SIMOTICS S motors against

unintentional movements that generate a voltage at

the terminals.

4. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems or

water.

5. Isolate or neutralize all hazardous energy sources, for example by closing switches,

grounding or short-circuiting, or closing valves.

6. Take measures to prevent reconnection of the energy sources.

7. Make sure that the machine is completely locked ... and that you have the right

machine.

After you have completed the work, restore operational readiness by performing the above

steps in the reverse order.

WARNING

Slipping on leaked oil

Leaked oil can result in slipping or falling and cause death or severe injury.

• Prevent oil from leaking

• Absorb leaked oil immediately with a binding agent for oil or similar.

• Rough up the hazardous location.

• Mark the hazardous location.

CAUTION

Burning hazard caused by hot surfaces

Some parts of the frame of electrical machines can reach temperatures in excess of 100°

C. Touching components when the machine is in operation can cause burns.

• Do not touch frame parts while the machine is in operation or immediately after machine

operation.

• Allow frame parts to cool off before starting any work.

CAUTION

Danger of scalding from the hot oil exiting the unit

Exiting hot oil can cause burns.

• Before starting any work, wait until the oil has cooled down to below 30° C.

CAUTION

Chemical burns and irritations caused by chemical cleaning agents

Chemical cleaning agents can be caustic or emit dangerous fumes. If these come into

contact with skin or if you inhale the fumes, this can cause injuries, e.g. chemical burns on

the skin or respiratory passages, or skin irritation.

• During cleaning, make sure that appropriate methods of extracting fumes are in place

and that you wear the appropriate protective gear (e.g. gloves, goggles, face masks).

• If using chemical cleaning agents, observe the instructions and any warnings provided

in the relevant safety data sheet. Chemical cleaning agents must be suitable for use

with the machine's components, particularly where plastic components are concerned.

WARNING

Danger to life caused by falling machine parts

The machine partially comprises heavy individual components. When removing the

machine, these components can fall. This can result in death, serious injury or material

damage.

• Secure the machine components that are being released so that they cannot fall.
