* When the control method is changed, the factory setting will change. The flux vector factory setting is given.
Setting Number of PG Pulses
Set the number of PG (Pulse Generator/Encoder) pulses in pulses/rotation. Set the number of A-phase or B-
phase pulses per 1 motor rotation in H7-01.
Matching PG Rotation Direction and Motor Rotation Direction
Constant H7-05 matches the PG rotation direction and the motor rotation direction. If the motor is rotating for-
wards, set whether it is A-phase driven or B-phase driven.

Example: Forward rotation of standard Yaskawa motor (PG used: Samtack (KK))
Forward
Command
Yaskawa standard PG used is A-phase driven (CCW) when motor rotation is forward.
Setting
Description
Range
Sets the speed deviation detec-
tion method.
0 to 50
Any speed deviation above the
H7-10 set level (set as a per-
centage of the maximum output
frequency) that continues for
the time set in H7-11 is
detected as a speed deviation.
Speed deviation is the differ-
ence between actual motor
speed and the reference com-
mand speed.
Used to set the PG disconnec-
tion detection time. PGO will 0.0 to
be detected if the detection time
continues beyond the set time.
