* 1. Gear output torque is expressed using the following equation.
(Gear output torque) = (servomotor output torque) × (gear) × (efficiency)
* 2. Maximum motor speed is up to 5000 min -1 at the shaft.
* 3. This brake is for holding (de-energization operation) and cannot be used to stop the servomo-
tor.
* 4. The allowable torque is limited by gear.
