1 Pressing the start button does not work
Cause 1 Wiring errors in the motor, limit switch, and control unit treatment Checking the wiring
Cause 2 Disconnection of motor stator windings and lead wires treatment Repairs and replacements
Cause 3 Electromagnetic switch or controller failure treatment repair
Cause 4 Limit switch failure treatment exchange
Cause 5 Forgetting to turn OFF (reset) after overload detection treatment Turn it OFF (reset) (See page 10 of the instruction manual)

2 The motor makes noise but does not move
Cause 1 Power supply voltage drop treatment Increase power supply capacity and consider power supply size
Return to list
3 Rated thrust is not generated
Cause 1 Power supply voltage drop treatment Increase power supply capacity and consider power supply size
Cause 2 Connection failure of the other device treatment Adjustment and friction plate replacement
Return to list
4 Poor stopping accuracy
Cause 1 Regenerative braking OFF treatment Dynamic brake circuit study
Cause 2 Excessive load treatment Load reduction and capacity considerations
