Note:
• The upper limit value changes when the E1-04 [Maximum Output Frequency] and d2-01 [Frequency Reference Upper Limit] values
change.
• When A1-02 = 6, 7 [Control Method Selection = AOLV/PM, CLV/PM], the drive changes o1-03 = 1 [0.01% (100% = E1-04)].
• This parameter sets the frequency reference of Multi-Step Speed 15.

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].

d2-01 Frequency Reference Upper
Limit
(0289)
When the frequency reference is more than the value set in d2-01 the drive will continue to operate at the value set in
d2-01.

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