d2: Reference Limits

d2 parameters set the upper and lower frequency limits to control the motor speed. Apply these parameters to for example, run the motor at low-speed due to mechanical strength concerns, or if the motor should not be run at low speed because of lubrication issues with the gears and bearings.

The upper frequency limit is set in d2-01 [Frequency Reference Upper Limit] and the lower limit is set in d2-02 [Frequency Reference Lower Limit].
