11
Range: 50%-100% (Default: 80%)
Description: Set the multiple of undervoltage for soft starter.
F27
Under Voltage Time
Range: 0s~120s (Default: 5s)
Description: Set soft starter undervoltage protection trigger delay time.
F28
Current Unbalance P.C.
Range: 20%~100% (Default: 40%)
Description: Parameter setting for current three-phase unbalance.
F29
Current Unbalance Time
Range: 0s~120s (Default: 10s)
Description: Set soft starter three phase current unbalance protection trigger delay time.
F30
Under Load P.C.
Range: 10%~100% (Default: 50%)
Description: Set the multiple of under load for soft starter.
F31
Under Load Time
Range: 1s~120s (Default: 10s)
Description: Set soft starter under load protection trigger delay time.
F32
Phase Sequence
Range: 0~2 (Default: 0)
Option: 0: Any
1: Positive
2: Negative
F33
IA Calibration
Range: 10%~1000% (Default: 100%)
Description: Calibration of the soft starter's current monitoring circuit to match the external current
measuring device.
The formula is as follows:
Calibration (%) = Current measured by an external device / Current displayed on the soft starter
For example: 102%=102A/100A
Note:
This adjustment value affects all current-based functions and protections.
F34
IB Calibration
Range: 10%~1000% (Default: 100%)
Description: The function same as parameter F33.
F35
IC Calibration
Range: 10%~1000% (Default: 100%)
Description: The function same as parameter F33.
F36
Voltage Calibration
Range: 10%~1000% (Default: 100%)
Description: Calibration of the soft starter's voltage monitoring circuit to match the external voltage
measuring device.
The formula is as follows:
Calibration (%) = Voltage measured by an external device / Voltage displayed on the soft starter
For example: 95%=380V/400V
F37
4-20mA Lower Calibration
