■ L8-05: Input Phase Loss Protection Sel
No.
(Hex.)
Name Description
Default
(Range)
L8-05
(04B1)
Input Phase Loss Protection
Sel
Sets the function to enable and disable input phase loss detection. 1
(0, 1)
0 : Disable
1 : Enabled
The drive measures ripples in DC bus voltage to detect input phase loss.
The drive detects phase loss when power supply phase loss occurs or the main circuit capacitor becomes unusable,
which causes PF [Input Phase Loss] to show on the keypad.
Disable the detection of the input power supply phase loss function in these conditions:
• During deceleration
• The run command is not input
• The output current is less than 30% of the drive rated current.
■ L8-07: Output Phase Loss Protection Sel
No.
(Hex.)
Name Description
Default
(Range)
L8-07
(04B3)
Output Phase Loss
Protection Sel
Sets the function to enable and disable output phase loss detection. The drive starts output phase loss
detection when the output current decreases to less than 5% of the drive rated current.
1
Note:
The drive can incorrectly start output phase loss detection when the motor rated current is very small compared to the drive rating.
0 : Disabled
1 : Fault when one phase is lost
If the drive loses one output phase, it will trigger LF [Output Phase Loss].
The output turns off and the motor coasts to stop.
2 : Fault when two phases are lost
If the drive loses more than one output phase, it will trigger LF [Output Phase Loss].
The output turns off and the motor coasts to stop.
■ L8-09: Output Ground Fault Detection
No.
(Hex.)
Name Description
Default
(Range)
L8-09
(04B5)
Output Ground Fault
Detection
Sets the function to enable and disable ground fault protection. Determined by o2-04
(0, 1)
0 : Disable
The drive will not detect ground faults.
1 : Enabled
If there is high leakage current or a ground short circuit in one or two output phases, the drive will detect GF [Ground
Fault].
Note:
If the ground path impedance is low, the drive can detect oC [Overcurrent], SC [Out Short Circuit or IGBT Fault], or ov [DC Bus
Overvoltage] instead of GF.
■ L8-10: Heatsink Fan Operation Selection
No.
(Hex.)
Name Description
Default
(Range)
L8-10
(04B6)
Heatsink Fan Operation
Selection
Sets operation of the heatsink cooling fan. 0
(0 - 2)
