Maximum permitted holding torque for short-time duty, maximum of 10 min at 50% cyclic duration factor

The torques listed in the table refer to a maximum ambient temperature of 40 °C, higher ambient temperatures lead to reduced power output. The drive is protected from overheating by a thermistor installed in the motor. The actual current profile depends on the application and the mechanical construction of the conveyor.
