SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
If you set the input level for terminals A1 and A2 and
L3-06
, the drive will use the smaller value for Stall Prevent
Level during Run.

Description
Default
(Range)
L3-11
(04C7)
Overvoltage Suppression
Select
Sets the overvoltage suppression function.
0
(0, 1)
0 : Disabled
The drive does not adjust the regenerative torque limit or the output frequency. If you apply a regenerative load, the
drive can detect an
ov [Overvoltage]
fault.
1 : Enabled
When a regenerative load increases the DC bus voltage, the drive decreases the regenerative torque limit and
increases the output frequency to prevent
ov
.

L3-17
(0462)
DC Bus Regulation Level
Sets the target value for the DC bus voltage when the overvoltage suppression function and the Decel
Stall Prevention function (Intelligent Stall Prevention) are active.
208/240 V: 375 V,
480 V: 750 V
(208/240 V: 150 - 400 V,
480 V: 300 - 800 V)
Note:
This value is initialized when
E1-01 [Input AC Supply Voltage]
is changed.
Sets this parameter for any of the following circumstances.
•
L3-11 = 1 [OV Suppression Function Select = Enabled]
.
•
L3-04 = 2 [Decel Stall Prevention Selection = Automatic Decel Reduction]
.

DC Bus Voltage Adjustment
Gain
Sets the proportional gain used to control the DC bus voltage.
1.00
(0.00 - 5.00)
Set one of these parameters to enable L3-20:
•
L3-04 = 2 [Decel Stall Prevention Selection = Automatic Decel Reduction]
•
L3-11 = 1 [Overvoltage Suppression Select = Enabled]
