Sel
(0381)
If the drive does not detect ouput pulses from the encoder for the time set in F1-14 [Encoder Open-Circuit Detect
Time], it will trigger PGo.
Note:
• Motor speed and load conditions can cause ov [Overvoltage] and oC [Overcurrent] faults.
• In AOLV control, set n4-72 = 1 [Speed Feedback Mode = With Encoder].
0 : Ramp to Stop
The drive ramps the motor to stop in the deceleration time. Fault relay output terminal MA-MC turns ON, and
MB-MC turns OFF.
1 : Coast to Stop
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 PGo and the drive continues operation. Only use this setting in special conditions to prevent
damage to the motor and machinery. The output terminal set for Alarm [H2-01 to H2-03 = 10] activates.
4 : No Alarm Display
The drive continues operation and does not show PGo on the keypad. Only use this setting in special conditions to
prevent damage to the motor and machinery.

F1-03 Overspeed Detection
Selection
(0382)
When the motor speed is more than the value set in F1-08 [Overspeed Detection Level] for longer than the time
set in F1-09 [Overspeed Detection Delay Time], the drive will detect oS.
0 : Ramp to Stop
The drive ramps the motor to stop in the deceleration time. Fault relay output terminal MA-MC turns ON, and
MB-MC turns OFF.
1 : Coast to Stop
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 oS and the drive continues operation. Only use this setting in special conditions to prevent
damage to the motor and machinery. The output terminal set for Alarm [H2-01 to H2-03 = 10] activates.

[Encoder (PG) Feedback Loss].
V/f CL-V/f OLV CLV AOLV
Sets the method to stop the motor or let the motor continue operating when the drive detects oS
[Overspeed].
