I have an AKM servo motor and AKD servo drive that works great in the constant torque operation mode (mode that was recommended in the NI user manual). However, I would like to operate the servo in a constant velocity mode. I have tried adjusting the settings using the AKM software but the motor will not turn when using MAX (following error). The operation mode is updated on the drive output from 00 (constant torque) to 01 (constant velocity). This is the only parameter that I have changed.
Equpment being used:
Ni PXI-7344 motion controller
UMI-7774 motion interface
AKM42E-ANCNC-00 BLDC motor with SFD
Single Axis AKD drive, Analog, 3A continuous current, 120/240 VAC
PXIe-1078 express chassis
PIXIe-8102 controller
Labview 2011
Does anyone have any suggestions on why the motor will not turn in constant velocity mode?
Thank you for your time.
