Encoder Divided Pulse Output

The encoder divided pulse output is a signal that is output from the encoder and processed
inside the SERVOPACK. It is then output externally in the form of two phase pulse signals
(phases A and B) with a 90° phase differential. At the host controller, it can be used as the posi-
tion feedback.
The following table describes the signals and output phase forms.

Remarks
• Rotary Servomotors
These encoder divided pulse
output pins output the number
of pulses per Servomotor reso-
lution that is set in Pn212
(Number of Encoder Output
Pulses). The phase difference
between phase A and phase B
is an electric angle of 90°.
• Linear Servomotors
These encoder divided pulse
output pins output pulses at the
resolution that is set in Pn281
(Encoder Output Resolution).
The phase difference between
phase A and phase B is an
electric angle of 90°.
These pins output one pulse
every Servomotor rotation.
