Holding torque at standstill
The motor holding torque is reduced by the current cutback function of the driver at
motor standstill. When operating the motor, take account of the motor torque drop at
the time of stopping.
•
Allowable torque
When operating the motor at a constant speed, use so that the torque does not exceed
the allowable torque in the specifications. Operating the motor in excess of the allowable
torque may cause damage to the gear part.
•
Speed range
Operate the motor at speeds within the speed range. Operating the motor at a speed
outside the speed range may result in a shorter gear life.
•
Backlash
The gear output shaft is subject to backlash. To reduce the effect of backlash, perform
positioning operations from one direction only-either from the CW direction or the CCW
direction.
•
Rotating direction of the gear output shaft
The relationship between the rotating direction of the motor shaft and that of the gear
output shaft changes as follows, depending on the gear type and gear ratio.
