Motor Feedback Wiring
Encoder feedback connections are made with the CFCS cable. This cable has an MS style
connector on the motor end and a 26-pin high density “D” connector on the drive end.
Figure 15: Motor Feedback Connector Pinout
Connection of encoder commutation signals to the drive
EN drives with a part number of 960500-08 or higher (part number label is located on the top
of the drive by the AC Input connector) are capable of receiving U, V and W commutation
signals from either a differential or common-collector source. Figure 15 shows the input
impedance for the U, U/, V, V/, W and W/ inputs on the drive. For single-ended encoder
outputs, leave U/, V/, and W/ unconnected at the drive.
EN drives with a part number of 960500 -07 or lower can only accept differential U,V,W,
signals.
Note
The indexing pulses A, A/, B, B/, Z, and Z/ must come from a differential source.
