Motor Control MID-7654 PCI-7340

Hello,

I'm configuring MAX settings for a servo motor with an embedded quadrature encoder.  I set up the motor on Axis-1 and I'm simply trying to drive the motor without a load.

The motor has been able to drive under stepper motor settings, but the move is jerky and I don't have access to the encoder feedback.  When I configure the motor as a servo, the encoder feedback is working properly.

Does anyone have any suggestions as to what to try?

Thanks!

Not sure I understand your post- you have a servo, and when configured as a servo the feedback works.

Why then are you trying to set it up as a stepper?

That original post was slightly confusing.

I meant to say that the servo doesn't drive under the "servo" settings in MAX.  It wasn't getting a power supply.

However, I applied a load to the motor and started tinkering with the PID settings and it began working (still slightly jerky).  I think I answered my own question...

Thanks anyway!
