Example of Forward/Reverse Rotation
Using Monitor Output
G3J-T-C
Note: Be sure to use a fuse or non-fuse breaker to protect the G3J.
Time Chart Example
Note: Switch between forward and reverse rotation only after the
motor rotation has come to a complete stop.
Monitor Output Usage Example (Motor
Stop Hold)
DC Model G3J-T@BL-C
Monitor Output Applications
•The monitor output will be ON while current is flowing to the main
circuit. Use the monitor output, e.g., to switch the operation
indicator, or to switch control signals during forward/reverse rotation
or when a mechanical brake is used.
•Be sure to use a surge absorber when connecting an inductive load
to the monitor output.

Time Chart
Note: 1. The soft-start time and soft-stop time depend on the load characteristics (e.g., inertia and friction factor) in addition to the starting torque,
ramp-up time, and ramp-down time. Therefore, the soft-start time or soft-stop time will not increase beyond a certain point if the ramp-up
time and ramp-down time are increased.
2. Due to the soft-stop control characteristics, the load current continues flowing even after the motor stops. Set to the optimum value
according to the application.
3. The operation indicator will light synchronized with the monitor output.
