Function Code Parameter Name Setting Range Default
F9-13
Output phase loss
protection
During running
0: Disabled
1: Enabled
Before running
0: Disabled
1: Enabled
01
Units position: It determines whether to perform output phase loss protection. If protection is
disabled but power output phase loss occurs, the AC drive does not detect the fault. At this
moment, actual current is larger than the current displayed on the operating panel.
Tens position: It takes about several seconds to detect output phase loss during running. In low-
frequency running application or application where risks exist in start with phase loss, set this
position to 1. In applications which have strict requirements on start time, set this position to 0.
6.6.3 Fault Reset
Function Code Parameter Name Setting Range Default
F9-09
Auto reset times 0 to 20 0
This function parameter sets permissible times of auto fault reset. If reset times exceed the value
set in this parameter, the AC drive will keep fault status.
Note
Ɣ
Undervoltage (Err09) is reset automatically when bus voltage recovers to
normal. It is not included in auto reset times.
Ɣ
Short-circuit to ground (Err23) cannot be reset automatically or manually. It can
only be reset after power down.
Function Code Parameter Name Setting Range Default
F9-10
Selection of DO action
during auto reset
0: Not act
1: Act
0
This function parameter decides whether digital output terminal set for fault output acts during
the fault reset.
Function Code Parameter Name Setting Range Default
F9-11
Delay of auto reset 0.1s to 100.0s 1.0s
This function parameter sets the delay of auto reset after the AC drive detects a fault.
