I have a 2 phase 48V stepper motor with a nominal current of 4.2A per phase and a holding torque of 2Nm. The motor is attached to a 16:1 planetary gearbox that is well greased. However, when I move the motor, I can easily stop the motor's movement with my hand.
I am using a DMC-2183 with a 24VDC option and a SDM-20640 powered at 48V.
How can I increase the torque of the motor?

Ty,
Set the amplifier gain for that axis to 2 AGn=3 where 'n' is A, B, C etc
This will set the current output to 3Amps/Phase which is the maximum for the SDM-20640.

Thank you for the quick response Andy. Unfortunately, setting AGC=2 causes my motor to not move at all. When I don't set the AG, the motor will move.
EDIT: I had forgotten to turn the motor off before attempting to change the AG. Thank you.

Ty,
I mixed two and three in my first response.
Set the amplifier gain for that axis to three (not two) AGn=3 where 'n' is A, B, C etc
