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].

V/f CL-V/f OLV CLV AOLV
Sets the Jog frequency reference according to the units set in o1-03
[Frequency Display Unit Selection]. Set H1-xx = 6 [Terminal Sx Function
Selection = Jog Reference Selection] to use the Jog frequency reference.
