3.1.3
SGMAH Servomotors With Low-backlash Gears
* 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%.
