Encoder Output Pulses
The encoder pulse output is a signal that is output from the linear scale and processed inside the SERVO-
PACK. It is then output externally in the form of two phase pulse signal (phases A and B) with a 90
phase dif-
ferential. It is used as the position feedback to the host controller.
Signals and output phase form are as shown below.
(1) Signals
For details on the phase C, refer to
(3) Encoder Output Pulse Signals from SERVOPACK with a Linear Scale by Ren-
(2) Output Phase Form
Note: The pulse width for phase C (origin pulse) changes according to the setting of the encoder output resolution (Pn281)
and becomes the same as that for phase A.
Even in reverse movement mode (Pn000.0 = 1), the output phase form is the same as that for the standard setting
(Pn000.0 = 0) above.

Encoder output pulse: phase A
The resolution of the pulse output
from the SERVOPACK to the host
controller is set in the parameter for
the encoder output resolution
(Pn281). Phase A and phase B are
different from each other in phase by
an electric angle of 90
.
