Wiring of GT60PG6/GT60PG6D is shown as follows:
■
Grounding Shield of Extension Encoder Card
On prerequisite that AC drive parameters are set properly, if PG card feedback speed or
position is instable, it indicates that PG card suffers electromagnetic interference. In this
case, connect shield of encoder signal lines to PE of the AC drive to restrain interference.
Connect inside of
ground bar to PE.
After installation of the PG card is done, PE of PG card is connected automatically. When
connecting encoder, connect shield of signal lines to PE of PG card to complete the shield
grounding.
To install PG card, remove screw in amplified position and align mounting holes of PG
card to the four fixing pins and fix PG card with the prepared M3 x 8 screws.

EMC Guidance
●
Do not bundle encoder cable and power cables together. Failure to comply will result
in encoder interference.
●
Motor housing must be connected to PE of the AC drive. Meanwhile, connect
grounding cable of motor to motor housing reliably. Failure to comply will result in poor
grounding effect.
●
An STP cable is suggested. For differential encoders, perform cable connection based
on differential pairs properly and connect shield to PE of the AC drive.
●
For large equipment applications where AC drive is far away from motor and motor
cable is longer than 10 m, grounding effect is not good due to influence of cable
inductance. In this case, encoder shield need not be connected to PE of AC drive.
