7 Troubleshooting
YASKAWA ELECTRIC TOBP C730600 52C 1000-Series Option PG-E3 Installation Manual 27
Noise interference along the PG
encoder cable is affecting the A
or B pulse. • Make sure the motor is rotating in the proper direction.
• Investigate problems on the load-side that may be causing the motor to rotate in
the opposite direction.
PG encoder is disconnected or is
not wired properly, or the PG
option or PG encoder are
damaged. • Rewire the PG encoder and make sure all wiring including shielded wiring is
properly connected
• If the problem continues after cycling power, replace the PG option or the PG
encoder.

Overspeed
The motor speed feedback exceeded the F1-08 setting.
Cause Possible Solution
Overshoot is occurring.
Increase the settings for C5-01 (Speed Control Proportional Gain 1) and reduce
C5-02 (Speed Control Integral Time 1).
