C7: DC Bus Voltage Control
C7-14
(759H)
Bias Voltage at
Operation Start
Vd Bias@Start
Normally, it is not necessary to change the setting of this
parameter. Adjusts the level to start regenerative operation
for automatic operation. Operation starts when the Voltage
Deviation (U1-73) exceeds the sum of C7-14 and C7-15.
Operation stops when Voltage Deviation goes below the
set value of C7-14.
200 V Class
Default: 2.0
Min.: 00.0
Max.: 50.0
400 V Class
Default: 4.0
Min.: 0.0
Max.: 100.0
C7-15
(75AH)
Voltage Hysteresis
Width at Operation
Start/Stop
Vd Hysteresis
Normally, it is not necessary to change the setting of this
parameter. Adjusts the level to start regenerative operation
for automatic operation. Operation starts when the Voltage
Deviation (U1-73) exceeds the sum of C7-14 and C7-15.
Operation stops when Voltage Deviation goes below the
set value of C7-14.
200 V Class
Default: 3.0

C7-16
(75BH)
Minimum Operation
Time
Minimum On Time
Sets the minimum operation time from the start of
operation to when operation stops in automatic operation.
Default: 1.00 s
Min.: 0.00 s
Max.: 600.00 s
C7-43

Input Voltage Offset
Adjustment
Vac Bias Adj Sel
There is normally no need to change this parameter from
the default value. This parameter is for factory setting.
If the setting is not correct, the regenerative unit may be
damaged.
0: Standard
1: Start offset adjustment. (The parameter returns to 0 after
it is set.)
2: Offset adjustment not required. (The parameter returns
to 0 after it is set.)
Default: 0
Range: 0 to 2
C7-50

Operation Ready
ON Delay Time
Conv READY delay
Sets the delay time to turn on the Operation Ready signal
(H2-†† = 6).
Default: 0 ms
Min.: 0 ms
Max.: 500 ms
C7-53
(111FH)
Automatic
Operation Stop
Power
Autorun Power
Sets the power to stop the automatic operation. When in
automatic operation, Regenerative unit stops automatic
operation when the power becomes lower than
regenerative load.
Default: 50%
Min.: 0%
Max.: 100%
