Description
Used to determine whether the fault output function of the DO takes effect during
the automatic fault reset of the AC drive. The fault output function of the DO is
defined by setting F5‑04 to 2.
F9-11
Fault auto reset interval
Address:
0xF90B
Min.:
0.1
Unit:
s
Max.: 100 Data type: UInt16
Default:
1
Change: In real time
Value Range:
0.1s to 100.0s
Description
This parameter defines the delay of auto fault reset after the AC drive reports a
fault.
F9-12
Input phase loss/Contactor pickup protection
Address:
0xF90C
Min.:
0
Unit:
‑
Max.: 13 Data type: UInt16
Default:
11
Change: In real time
Value Range:
Ones (position): Input phase loss protection selection
0: Input phase loss detection inhibited
1: Input phase loss detected by software and hardware
2: Input phase loss detected by software
3: Input phase loss detected by hardware
Tens (position): Contactor pickup/Fan fault protection
0: Inhibited
1: Enabled
Description
This function parameter determines whether to perform input phase loss or
contactor pickup protection through the ones and tens position.
After the input phase loss protection function is enabled, if the three‑phase input
power supply is abnormal, or the driver board, lightning protection board, main
control board, or rectifier bridge is abnormal, the AC drive will report E12.00
(input phase loss).
For models of 450 kW and below, the tens position is used to set the contactor
pickup protection function. For for models of 500 kW and above, the tens position
is used to set the fan fault selection.
