Using PG Speed Control Card
There are two types of PG Speed Control Cards that can be used for Flux Vector Control.
PG-B2: A/B phase pulse inputs, complementary outputs
PG-X2: A/B/Z phase pulse inputs, line driver outputs
For the connection diagram, refer to page 2-30 to 2-31.
Setting Number of PG Pulses
Set the number of PG (pulse generator/encoder) pulses in pulses per motor revolution. Set the number of A-
phase or B-phase pulses per 1 motor rotation in F1-01.
F1-08
Overspeed Detec-
tion Level
Configures the overspeed fault (OS) detec-
tion.
OS fault will occur, if the motor speed feed-
back is greater than the F1-08 setting for a
time longer than F1-09. F1-08 is set as a per-
centage of the maximum output frequency
(E1-04). See F1-03.

Deviation Detec-
tion 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 percent-
age of the maximum output frequency (E1-
04).
Speed deviation is the difference between
actual motor speed and the Frequency Refer-
ence Command. See F1-04.

Detection Time

PGO will be detected if no PG pulses are
detected for a time longer than F1-14. See F1-
