8.4 CN4, 5 Axis I/O Connector
CN4 is for X axis and CN5 is for Y axis of input/output signals. CN4 and CN5 are completely the same pin assignments.
MR210AU does not have CN5.
“n” in the table indicates X in CN4 and Y in CN5.

Driving pulse output signal is output from differential line-drive (AM26C31 or equivalent) output.
nP+N is the reverse output of nP+P and nP-N is the reverse output of nP-P. At resetting, positive output (nP+P, nP-P) becomes low
level and reverse output (nP+N, nP-N) becomes hi level. A connection example with a motor driver is shown as follows:
