Degrees of protection for AC motors A suitable degree of protection must be selected to protect the machine against the following hazards depending on the relevant operating and environmental conditions: * Ingress of water, dust and solid foreign objects, * Contact with or approach to rotating parts inside a motor and * Contact with or approach to live parts. IP651) Jet-water from any direction IP671) Motor under defined pressure and time conditions under water Recommended degrees of protection for AC motors When cooling lubricants are used, protection against water alone is inadequate. The IP rating should only be considered here as a guideline. The motors may have to be protected by suitable covers. Attention must be paid to providing suitable sealing of the motor shaft for the selected degree of protection for the motor (for 1FT7: degree of protection IP67 and flange 0). The table can serve as a decision aid for selecting the proper degree of protection for motors. A permanent covering of liquid on the flange must be avoided when the motor is mounted with the shaft extension facing upwards (IM V3, IM V19).

If the motor and mounted component are separately balanced before they are assembled, then the process used to balance the belt pulley or coupling must be adapted to the motor balancing type. The following different balancing methods are used on motors of types SIMOTICS M-1PH8: * Half-key balancing * Full-key balancing * Plain shaft extension The letter H (half key) or F (full key) is printed on the shaft extension face to identify a half-key balanced or a full-key balanced SIMOTICS M-1PH8 motor. Coolant temperature (ambient temperature) and installation altitude Operation (unrestricted): -15 C to +40 C (5 F to 104 F) The rated power (rated torque) is applicable to continuous duty (S1) according to EN 60034-1 at rated frequency, a coolant temperature of 40 C (104 F) and an installation altitude of 1000 m (3281 ft) above sea level. Apart from the SIMOTICS M-1PH8 motors, all motors are designed for temperature class 155 (F) and utilized according to temperature class 155 (F). The SIMOTICS M-1PH8 motors are designed for temperature class 180 (H). For all other conditions, the factors given in the table below must be applied to determine the permissible output (torque).

In general, motors with a plain shaft are recommended for systems with the most stringent vibrational quality requirements. For full-key balanced motors, we recommend belt pulleys with two opposite keyways, but only one feather key in the shaft extension.

This sensor is a semi-conductor that changes its resistance depending on temperature in accordance with a defined curve. Siemens converters determine the motor temperature using the resistance of the temperature sensor. Their parameters can be set for specific alarm and shutdown temperatures. The SIMOTICS L-1FN3/-1FN6 and SIMOTICS T-1FW6 motors are additionally equipped with PTC sensors (PTC elements). In these motor series, evaluation is performed using the SME120/SME125 Sensor Module External or TM120 Terminal Module (see SINAMICS S120 drive system). The KTY84-130 temperature sensor is embedded in the winding overhang of the motor like a PTC thermistor. The sensor is evaluated in the SINAMICS S120 drive system as a standard function. If the motors are operated on converters that do not feature a KTY84 evaluation circuit, the temperature can be measured with the external 3RS1040 temperature monitoring relay.

For these motors as well as external encoders, the encoder signals must be connected to SINAMICS S120 via Sensor Modules. The first letters of the short designation define the encoder type. This is followed by the resolution in signals per revolution if S/R is specified (for encoders without DRIVE-CLiQ interface) or in bits if DQ is specified (for encoders with DRIVE-CLiQ interface).

There is no further conversion of the encoder signal in the drive system. The motor-internal encoders are the same encoders that are used for motors without a DRIVE-CLiQ interface. Motors with a DRIVE-CLiQ interface simplify the commissioning and diagnostics, for example, due to automatic identification of the encoder system.

In the case of a 2-pole resolver, the evaluation electronics may output an additional zero pulse per encoder revolution.
