5.3.6 Encoder Output Pulses
5-30
(3) Encoder Output Pulse Signals from SERVOPACK with a Linear Scale by Renishaw
plc
The output position of the zero point signal (Ref) will depend on the direction of movement for some models
of linear scale by Renishaw plc.

In such case, the phase-C pulses of the SERVOPACK are output at two positions.

For details on the specifications of the zero-point signals for a linear scale, refer to the manual for the Ren-
ishaw linear scale.

Second pulse is half as wide
as the phase-A pulse. No zero point signal (Ref) is sent from the linear scale.
However, a phase-C pulse will be sent from the SERVOPACK
when moving in the reverse direction, because it is the same
forward from which a phase-C pulse was sent from the
SERVOPACK when moving in a forward direction.
