■
S1-02: Voltage Reduction Rate
No.
(Hex.)
Name Description
Default
(Range)
S1-02
(3201)
Voltage Reduction Rate Sets the rate at which the drive will decrease the output voltage as a percentage of the V/f pattern
when operating with no load. 50.0%
(50.0 - 100.0%)
■
S1-03: Voltage Restoration Level
No.
(Hex.)
Name Description
Default
(Range)
S1-03
(3202)
Voltage Restoration Level Sets the level at which the drive will start to restore the voltage as a percentage of the drive rated
torque. 20.0%
(0.0 - 90.0%)
■
S1-04: Voltage Restoration Off Level
No.
(Hex.)
Name Description
Default
(Range)
S1-04
(3203)
Voltage Restoration Off
Level Sets the level at which voltage restoration for the V/f pattern is complete as a percentage of the drive
rated torque. If the output is more than
S1-04 , the drive will control the voltage as specified by the V/
f pattern setting.
50.0%
(10.0 - 100.0%)
Note:
The lower limit of this parameter is the value of S1-03 [Voltage Restoration Level] + 10.0%.
■
S1-05: Volt Restore Sensitivity Time K
No.
(Hex.)
Name Description
Default
(Range)
S1-05
(3204)
Volt Restore Sensitivity
Time K Sets the level of sensitivity of the output torque and LPF time constant for the voltage reduction rate.
You can adjust the level of sensitivity with the load response. 1.000 s
(0.000 - 3.000 s)
■
S1-06: Volt Restore Impact Load Time K
No.
(Hex.)
Name Description
Default
(Range)
S1-06
(3205)
Volt Restore Impact Load
Time K Sets the voltage restoration time constant when you add an impact load. 0.050 s
(0.000 - 1.000 s)
■
S1-07: Output Phase Loss Level
No.
(Hex.)
Name Description
Default
(Range)
S1-07
(324C)
Output Phase Loss Level Decreases the output phase loss level when Dynamic Noise control is active. 100.0%
(10.0 - 100.0%)
◆
S2: Sequence Run Timers
S2 parameters set the programmable run timers for Real Time Clock (RTC). The timers set the drive to start and stop
automatically at specified times. You can set the timers to run daily, on weekdays, on weekends, or only on specific
days of the week.
■
Sequence Timer 1
When the current time reaches the S2-01 [Timer 1 Start Time] value, the drive will do the S2-04 [Timer 1 Sequence
Selection] action. When the current time reaches the S2-02 [Timer 1 Stop Time] value, the drive will stop the S2-04
action. To use this function, set the current day in S2-03 [Timer 1 Day Selection] .
• When S2-04 = 0 [Digital Out Only] or the terminal set for H1-xx = 51 [MFDI Function Selection = Sequence
Timer Disable] is active:
Sequence Timer 1 has no effect on the drive Run command. The drive starts correctly based on the status of the Run
command source set in
b1-02 [Run Command Selection 1] .
