4.4 Connecting the Synchronous Feed Encoder
The ENC connector is used to connect the synchronous feed encoder. Use the CS050 or CS054
connector set (optional, with both ends) when manufacturing the R050 or R054 cable. (Refer to the
cable manufacturing drawings for details.)
Note that the synchronous feed encoder may be connected via the spindle drive unit.
