Note:
• On drives with software versions PRG: 01021 and later, this function is enabled.
The “ PRG ” column on the nameplate on the right side of the drive identifies the software version. You can also use
U1-25
[SoftwareNumber FLASH] to identify the software version.
• The upper limit value changes when the
E1-04 [Maximum Output Frequency]
and
d2-01 [Frequency Reference Upper Limit]
values
change.
• This parameter sets the frequency reference of Multi-Step Speed 16.

d1-17: Jog Reference
No.
(Hex.)
Name Description
Default
(Range)
d1-17
(0292)
RUN
Jog Reference
Sets the 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.
6.00 Hz
(0.00 - 590.00 Hz)
Note:
The upper limit value changes according to the value set in E1-04 [Maximum Output Frequency] and d2-01 [Frequency Reference
Upper Limit]
.
◆
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.
(Hex.)
Name Description
Default
(Range)
d2-01
(0289)
Frequency Reference Upper
Limit
Sets maximum limit for all frequency references. The maximum output frequency is 100%.
100.0%
(0.0 - 110.0%)
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.
(Hex.)
Name Description
Default
(Range)
d2-02
(028A)
Frequency Reference
Lower Limit
Sets minimum limit for all frequency references. The maximum output frequency is 100%.
0.0%
(0.0 - 110.0%)
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.
(Hex.)
Name Description
Default
(Range)
d2-03
(0293)
Analog Frequency Ref
Lower Limit
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%.
