Maximum motor speed is up to 4000 min -1 at the shaft.* 2. Gear output torque is expressed using the following equation.1(Gear output torque) = (servomotor output torque) × ( gear ratio ) × (efficiency)* 3. The instantaneous peak torque values indicated with ∗3 are limited by the gear, so use the followingservomotor instantaneous peak torque. In this case, set torque limit parameters Pn402 and 403 for theSERVOPACK at 250%.3-16
