Adjustment
*For encoder cables longer than 15m/50ft, JM1 should be set to position 2-3 to slow down
the serial clock. For shorter cable lengths, JM1 should stay in position 1-2.
** For encoder cables longer than 15m/50ft, it is recommended to connect the
–SENSE and
+SENSE lines into the terminal block and JM2 set to position 2-3. The drive will automatically
produce proper voltage on the encoder if JM2 is set to position 2-3. If JM2 is set to position 1-
2, the remote power sense is disabled and the sense wires do not need to be connected. The
maximum cable length is 100m (328ft).
