For YASKAWA’s inverter motor with PG, PG is installed at the opposite drive
end. Then, phase A lags phase B by a phase angle of 90
_
at motor forward run.
(Motor runs CCW as viewed from PG.) Therefore, when using this motor or
similar motors, connect phases A and B to the option card after replacing phase
output. The pulse monitor on this option shows phase A leading phase B by a
phase angle of 90
_
.
Make sure the followings when wiring.
S
To prevent noise, use shielded wire and separate from heavy current circuits
(200VAC or greater) or relay drive circuits. (Wire length to the PG connec-
tor must be 50m or shorter.)
S
Connect both ends of the unused wire of the shielded wire to the 0V termi-
nal.
S
Connect the grounding lead wire (E) to pin 12 of the control board of the
inverter.

Notes on selecting cables
Too thick a cable applies pressure to the option card and may lead to failure.
Too thin a cable may lead to imperfect contact or a break in the wire.
