(0381)
PGo is detected when the drive does not detect output pulses from the encoder for an amount of time longer than
or equal to the value set in F1-14 [PG Open-Circuit Detection Time].
Note:
• Faults such as ov [DB Bus Overvoltage] and oC [Overcurrent] may occur depending on the motor speed and load conditions.
• When using Advanced Open Loop Vector Control, this is enabled when n4-72 = 1 [Encoder Option Select for Advanced Open Loop
Vector Control = With PG].
0 : Ramp to stop
The drive ramps the motor to stop according to the deceleration time. The terminal turns on when H2-xx = E
[MFDO Function Select = Fault] is set.
1 : Coast to stop
The drive shuts off output and the motor coasts to stop. The terminal turns on when H2-xx = E.
2 : Fast Stop (use C1-09)
The drive stops the motor using the deceleration time set in C1-09 [Fast Stop Time]. The terminal turns on when
H2-xx = E.
3 : Alarm only
PGo appears on the keypad, and operation continues. This setting is not normally used as the motor and machine
is protected from damage.
4 : No alarm display
Operation continues without the display of PGo on the keypad. This setting is not normally used as the motor and
machine is protected from damage.

F1-03: Operation Select at Overspeed
No.

(Hex.)
F1-03 Operation Select at
Overspeed
(0382)
Detects oS when the motor speed exceeds the value set in F1-08 [Overspeed Detection Level] for an amount of
time longer than or equal to the value set in F1-09 [Overspeed Detection Delay Time].
0 : Ramp to stop
The drive ramps the motor to stop according to the deceleration time. The terminal turns on when H2-xx = E
[MFDO Function Select = Fault].
1 : Coast to stop
The drive shuts off output and the motor coasts to stop. The terminal turns on when H2-xx = E.
2 : Fast Stop (use C1-09)
The drive stops the motor using the deceleration time set in C1-09 [Fast Stop Time]. The terminal turns on when
H2-xx = E.
3 : Alarm only

V/f CL-V/f OLV CLV AOLV
Selects the motor operation when PGo [PG Disconnect] is detected.
V/f CL-V/f OLV CLV AOLV
Selects the motor operation when oS [Overspeed] is detected.
