Subject to
inverter model
“Under-voltage” refers to too low voltage at AC input side.
“Input phase loss” refers to phase loss of three-phase power supply, 5.5 kW and below
inverters have not got this function.
“Output phase loss” refers to phase loss of inverter three-phase wirings or motor wirings.
·““phase loss” signal filtering constant is used for the purpose of eliminating disturbance to
avoid mis-protection. The greater the set value is, the longer the filtering time constant is and
the better for the filtering effect.
F737 Over-current 1 protection

1: Valid
Mfr’s value: 1
F738 Over-current 1 protection coefficient Setting range: 0.50

F739 Over-current 1 protection record
F738= OC 1 value/inverter rated current.
In running status, F738 is not allowed to modify. When over-current occurs, OC1 is displayed
F741 Analog disconnected protection
Setting range:
0: Invalid
1: Stop and AErr displays.
2: Stop and AErr is not displayed.
3: Inverter runs at the min
frequency.
4: Reserved.
Mfr’s value: 0
F742 Threshold of analog disconnected
protection (%)
Setting range: 1~100
Mfr’s value: 50
When the values of F400 and F406 are lower than 0.01V, analog disconnected protection is
invalid.
When F741 is set to 1, 2 or 3, the values of F400 and F406 should be set to 1V-2V, to avoid the
error protection by interference.
Analog disconnected protection voltage=analog channel input lower limit * F742. Take the AI1
