Parameter Groups
‑264‑
This parameter defines the voltage threshold for recovering from power dip ride‑
through. 100% corresponds to 540 V. This value is slightly lower than the bus
voltage before power failure.
Upon power loss, the bus voltage is maintained at about F9‑62 (Threshold of
power dip ride‑through function enabled). When the power supply recovers, the
bus voltage rises from F9‑62 (Threshold of power dip ride‑through function
enabled) to F9‑60 (Threshold of power dip ride‑through function disabled). During
this period, the output frequency of the AC drive keeps decreasing until the bus
voltage reaches F9‑60 (Threshold of power dip ride‑through function disabled).
F9-61
Duration for judging voltage recovery from power dip ride-through
Address:
0xF93D
Min.:
0
Unit:
s
Max.: 100 Data type: UInt16
Default:
0.5
Change: In real time
Value Range:
0.0s to 100.0s
Description
Used to set the time required for the bus voltage to rise from F9‑60 (Threshold of
power dip ride‑through function disabled) to the voltage before power loss.
F9-62
Voltage to determine the action of power dip ride-through
Address:
0xF93E
Min.:
60
Unit:
%
Max.: 100 Data type: UInt16
Default:
80
Change: In real time
Value Range:
60% to 100%
Description
This parameter defines the bus voltage level upon power failure. When a power
loss occurs, the bus voltage is retained at a value around F9‑62 (Threshold of
power dip ride‑through function enabled).

Runaway protection time in FVC mode
Address:
0xF93F
Min.:

Unit:

Max.: 10000 Data type: UInt16
Default:
0
Change:
At stop
Value Range:
0 to 10000
