1)
Based on input speed of 1500 RPM. See page 217 for details on torque calculations..
2)
Maximum momentary torque for emergency stops or heavy shock load. (Admissible stops per life of gearhead = 1,000 stops maximum.)
* Motor shaft adapter code (shaft diameter max - mm): ME10 (19), ME20 (32), ME30 (38)
