* 1. Maximum motor speed is up to 4000 min
* 2. Gear output torque is expressed using the following equation.
(Gear output torque) = (servomotor output torque) ×
* 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%.
