Di󱐯erential output of encoder signal (A-phase, B-phase, Z-phase) which has been processed
with pulse division ratio.
Be sure to connect a termination resistor to the receiver circuit of the host controller.
Approximately 220 Ω (1/4W or more)
Signal ground of the communication IC in the output circuit is connected to signal ground
inside the drive.
