Time
The SERVOPACK records the position where
the phase-C pulse was output for movement
in the forward direction, and the phase-C
pulse is also output for reverse movement.

ON the power supply
The encoder's phase-C pulse (CN1-19 and CN1-20) is not output when the origin detec-
tion position is passed for the first time in the reverse direction after the power supply is
turned ON.
However, after the origin detection position is passed in the forward direction and the
encoder’s phase-C pulse is output, it will then also be output when the origin detection
point is passed in the reverse direction.

The encoder’s phase-C pulse is output when the origin detection position is passed for
the first time in the forward direction after the power supply is turned ON. After that, the
phase-C pulse is output whenever the origin detection position is passed in the forward or
reverse direction.

Even after origin 1 has been passed in
the forward direction, the phase-C pulse
is not output here because origin 2 is
passed in the reverse direction.
