Hello @Curtis_Weyenberg
synchronuous motors do have a lower torque constant above the stall torque/current.
See " TCTRANS_MODE = 0 (DEFAULT)":
Torque Calculation - Automation Help
The torque constant of 1.63 (MOTOR_TORQUE_STALL / MOTOR_CURR_STALL) for this motor is only valid in the continuous operation area. In the pulse operation area the torque constant gets lower and is MOTOR_TORQUE_MAX / MOTOR_CURR_MAX → 69 Nm / 52,6 A = ~1,312 Nm/A.
With that torque constant and the ACOPOS maximum current of 37,7 A you will reach ~49-50 Nm.
Best regards
Lukas
