Encoder Signal Loss Detect Sel

Sets the method to stop the motor or let the motor continue operating when the drive detects PGo [Encoder (PG) Feedback Loss].

(0 - 4)

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 H2-04 = 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.
