3.1.3 SGMAH Servomotors With Low-backlash Gears
3-10
* 1. Maximum motor speed is up to 4000 min
-1
at the shaft.
* 2. Gear output torque is expressed using the following equation.
(Gear output torque) = (servomotor output torque) × × (efficiency)
* 3. The instantaneous peak torque values indicated with ∗3 are limited by the gear, so use the following
servomotor instantaneous peak torque. In this case, set torque limit parameters Pn402 and 403 for the
SERVOPACK at 250%.
Note: The no-load torque for a servomotor with gears is high immediately after the servomotor starts, and
it then decreases and becomes stable a few minutes later. This is a common phenomenon caused by
grease being circulated in the gear and not by a faulty gear.
