PG Parameter
PG Pulses/Rev Sets the number of pulses per revolution (PPM) of the encoder
(pulse generator). 0 to

F1-02
Operation Selection at PG
Open Circuit (PGO)
PG Fdbk Loss Sel
Sets stopping method when a PG open circuit fault (PGO) occurs.
See parameter F1-14.
0: Ramp to stop - Decelerate to stop using the active deceleration
time.
1: Coast to stop
2: Fast - Stop - Decelerate to stop using the deceleration time in
C1-09.
3: Alarm Only - Drive continues operation.

Operation Selection at
Overspeed (OS)
PG Overspeed Sel
Sets the stopping method when an overspeed (OS) fault occurs. See
F1-08 and F1-09.
0: Ramp to stop - Decelerate to stop using the active deceleration
time.
1: Coast to stop
2: Fast - Stop - Decelerate to stop using the deceleration time in
C1-09.
3: Alarm Only - Drive continues operation.

F1-04
Operation Selection at
Deviation
PG Deviation Sel
Sets the stopping method when a speed deviation (DEV) fault
occurs. See F1-10 and F1-11.
0: Ramp to stop - Decelerate to stop using the active deceleration
time.
1: Coast to stop
2: Fast - Stop - Decelerate to stop using the deceleration time in
C1-09.
3: Alarm Only - Drive continues operation.

PG Rotation Selection
PG Rotation Sel
0: Fwd=C.C.W. - Phase A leads with forward run command.
(Phase B leads with reverse run command.)
1: Fwd=C.W. - Phase B leads with forward run command. (Phase
A leads with reverse run command.)

F1-06
PG Division Rate (PG Pulse
Monitor)
PG Output Ratio
Sets the division ratio for the pulse monitor of the PG-B2 encoder
feedback option board. This function is not available with the
PG-X2 option board.
Division ratio = (1+ n) /m (n=0 to 1, m=1 to 32)
The first digit of the value of F1-06 stands for n, the second and the
third stand for m. (from left to right).
The possible division ratio settings are:

Integral function during
accel/decel selection
PG Ramp PI/I Sel
Sets integral control during acceleration/deceleration to either
enabled or disabled.
0: Disabled - The integral function is not used while accelerating
or decelerating.
1: Enabled - The integral function is used at all times.

F1-08
Overspeed detection level
PG Overspd Level
Configures the overspeed fault (OS) detection.
OS fault will occur, if the motor speed feedback is greater than the
F1-08 setting for a time longer than F1-09. F1-08 is set as a
percentage of the maximum output frequency (E1-04). See F1-03. 0 to 120 115% - A - A

Excessive speed deviation
detection level
PG Deviate Level
Configures the speed deviation fault (DEV) detection.
DEV fault will occur if the speed deviation is greater than the
F1-10 setting for a time longer than F1-11. F1-10 is set as a
percentage of the maximum output frequency (E1-04).
Speed deviation is the difference between actual motor speed and
the frequency reference command. See F1-04.
