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 sets o1-03 = 1 [0.01% (100% = E1-04)].

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
No.
Name
(Hex.)
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.
■
d2-02: Frequency Reference Lower Limit
No.
Name
(Hex.)
d2-02 Frequency Reference
Lower Limit
(028A)
When the frequency reference is less than the value set in d2-02, the drive will continue to operate at the value set
in d2-02. The motor will accelerate to the d2-02 value after the drive receives a Run command and a lower
frequency reference than d2-02 has been entered.
■
d2-03: Analog Frequency Ref Lower Limit
No.
Name
(Hex.)
d2-03 Analog Frequency Ref
Lower Limit
(0293)
This parameter does not change the lower limit of Jog reference, frequency reference for multi-step speed
operation, or the auxiliary frequency reference.
The drive operates at the value set in d2-03 when the frequency reference decreases to less than the value set in
d2-03.

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.
Figure 12.63 Upper and Lower Frequency Limits
V/f CL-V/f OLV CLV AOLV
Sets maximum limit for all frequency references. The maximum output frequency is 100%.
V/f CL-V/f OLV CLV AOLV
Sets minimum limit for all frequency references. The maximum output frequency is 100%.
V/f CL-V/f OLV CLV AOLV
Sets the lower limit for the master frequency reference (the first frequency of the multi-step speed
reference) as a percentage. The maximum output frequency is 100%.
