Re: Min speed on the CIMs?

Assuming what you are asking for is open-loop motor performance curves (as opposed to closed-loop speed control capability of the motor controller), since you mentioned PWM (and not CAN)...

Note sure if this answers your question, but here is a link to CIM datasheet which has
the motor performance curves (speed/current/torque):
