The output turns off and the motor coasts to stop. Fault relay output terminal MA-MC turns ON, and MB-MC turns
OFF.
2 : Fast Stop (Use C1-09)
The drive stops the motor in the deceleration time set in
C1-09 [Fast Stop Time]
. Fault relay output terminal MA-MC
turns ON, and MB-MC turns OFF.
3 : Alarm Only
The keypad shows
oH
and the drive continues operation. The output terminal set for
Alarm [H2-01 to H2-03 = 10]
activates.
4 : Operate at Reduced Speed (L8-19)
The drive decelerates to the level set in
L8-19 [Freq Reduction @ oH Pre-Alarm]
and continues operation.
oH

on the keypad.
oH flashes on the keypad. When the alarm is output, the drive decelerates each 10 seconds. If the drive decelerates 10
times and the alarm continues to be output, the output terminal set for
oH Pre-Alarm Reduction Limit [H2-01 to H2-
03 = 4D]
activates. When the alarm is not output during deceleration, the drive accelerates until it is at the frequency
reference that was applicable before the alarm was turned off.

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.
