F1-04 Operation Selection at Speed Deviation (DEV)
This parameter sets the stopping method when a speed deviation fault (DEV) occurs according to the OS detection level and
detection time set in parameter F1-08 and F1-09, respectively.
F1-05 PG Rotation Selection
This parameter sets the relationship between motor rotation direction and PG polarity. The motor rotation direction applies
when viewing the motor shaft from the load side.
F1-05 PG Division Rate
Setting Range: 1 to 132
Factory Default: 1
This parameter 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
where n = 0 to 1 and m = 1 to 32
The first digit of the value of F1-06 stands for n, the second and the third digit stand for m (from left to right).
The possible division ratio settings are:
F1-07 Integral Function During Accel / Decel Selection
This parameter enables or disables the speed control (ASR) integral operation during acceleration or deceleration.
F1-08 Overspeed Detection Level
Setting Range: 0 to 120 %
Factory Default: 115 %
Setting Description
0 Ramp to Stop - Decelerate to stop using 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. (factory default)
Setting Description
0 Forward = Counter Clock-wise - Phase A leads with forward run command. (factory default)
1 Forward = Clock-wise - Phase B leads with forward run command.
Setting Description
0 Disable - Integral function is not used during accel or decel. (factory default)
1 Enable - Integral function is used at all times.
F1-05 = 1 16
n = 1 m = 16
Division Ratio = (1 + 1) / 16 = 0.125
Example:
1/32 ≤ F1-06 ≤ 1
