(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.
