*1 Parameters set when using the Closed Loop V/f Control method.
*2 Parameters to set an option card connected to CN5-B.
■ F1-01: Encoder 1 Pulse Count (PPR)
No.
(Hex.)
Name Description
Default
(Range)
F1-01
(0380)
Encoder 1 Pulse
Count (PPR)
Sets the number of output pulses for each motor revolution.
1024 ppr
(1 - 60000 ppr)
■ F1-02: Encoder Signal Loss Detect Sel
No.
(Hex.)
Name Description
Default
(Range)
F1-02
(0381)
Encoder Signal Loss
Detect Sel
Sets the method to stop the motor or let the motor continue operating when
the drive detects a PGo [Encoder (PG) Feedback Loss].
1
(0 - 4)
When 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 to stop in the set deceleration time. Fault relay output terminal MA-MC activates and terminal
MB-MC deactivates.
1 : Coast to Stop
The drive output shuts off and the motor coasts to stop. Fault relay output terminal MA-MC activates and terminal
MB-MC deactivates.
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 activates and terminal MB-MC deactivates.
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
No.
(Hex.)
Name Description
Default
(Range)
F1-03
(0382)
Overspeed Detection
Selection
Sets the method to stop the motor or let the motor continue operating when
the drive detects a oS [Overspeed].
1
(0 - 3)
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] trigger oS.
0 : Ramp to Stop
The drive ramps to stop in the set deceleration time. Fault relay output terminal MA-MC activates and terminal
MB-MC deactivates.
1 : Coast to Stop
The drive output shuts off and the motor coasts to stop. Fault relay output terminal MA-MC activates and terminal
MB-MC deactivates.
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 activates and terminal MB-MC deactivates.
