set the frequency reference input method and dead band range. They also set the field
weakening function.
WARNING!
Sudden Movement Hazard. Use fast stop circuits to safely and quickly stop the drive. After you wire the fast stop
circuits, you must check their operation. Test the operation of the fast stop function before you use the drive. If you do not test the
fast stop circuit before you operate the drive, it can cause serious injury or death.

Figure 5.32 Frequency Reference Setting Hierarchy
*1
The drive uses the smallest value of
Y1-40 [Maximum Speed]
,
E1-04 [Maximum Output Frequency]
, or
d2-01 [Frequency Reference
Upper Limit]
for Frequency Reference Upper Limit. When the drive is in Emergency Override Mode, it uses the smallest value of
Y1-40
,
E1-04
,
d2-01
, or
S6-10 [Emergency Override Max Speed]
.
*2
The drive uses the largest value of
Y1-06 [Minimum Speed]
,
Y4-12 [Thrust Frequency]
, or
d2-02 [Frequency Reference Lower Limit]
for
Frequency Reference Lower Limit. When the drive is in Emergency Override Mode, it uses the largest value of
Y1-06
,
Y4-12
,
d2-02
, or
S6-09 [Emergency Override Min Speed]
.
■
Multi-Step Speed Operation
The drive has a multi-step speed operation function that can set many frequency references in advance. Set frequency
references in
d1-xx parameters
. You can select the set frequency references with MFDI signals from an external
source. Activate and deactivate the digital input to select the frequency reference to change the motor speed in steps.
You can use the 8-step frequency reference and one Jog Frequency Reference (JOG command) to switch the speed to
the maximum 9-step speeds.
