Differential output of encoder signal divided and multiplied
(equivalent to RS-422)
SG:
Signal ground of the communication IC in the output circuit.
This signal is connected to signal ground inside the amplifier.
It is isolated from control power (G24 V,
COM－
). Make the
connection to signal ground of the communication IC of the
host controller.

・No.276.0, No.278.0
If Z-phase pulse width is too small to be measured accurately
by the host controller, decrease frequency division ratio or
rotational speed to increase the pulse width.
Pulse width [ms]
= 2 / rotational speed [r/min] / (division ratio × 2
17
) × 60 × 1,000.
