PowerFlex DC Digital Encoder Terminal Block
The encoder connection cables should always be connected directly to the
terminals on the encoder terminal block. The encoder cable must be made up of
twisted pairs with the shield connected to the shield ground on the drive side. Do
not connect the shield to ground on the motor side. In some cases (i.e., cable
lengths that exceed 100 meters), it may be necessary to ground the shield of each
twisted pair on the power supply. Refer to Appendix A of the PowerFlex Digital
DC Drive User Manual, publication 20P-UM001
, for Digital Encoder
specifications.
