Standard Models and Specifications
Note The GSEL signal is not allocated by default. Input terminal allocations (CN1 pins 40 to 46) can be
changed by setting Pn50A.0 (input signal selection mode) to 1. The GSEL signal is allocated by
Pn50d.2.

Note This signal will remain ON for approximately 250 ms after input of the SEN signal when using an
absolute encoder.

Servomotor encoder signals are output as divided phase-difference pulses according to the encoder
dividing rate setting (Pn201). The output form is line driver output, and conforms to EIA-RS-422A.
Receive the signals with a line driver or high-speed photocoupler.
By inputting the SEN signal (low to high), absolute data is first output as serial data from the phase A,
and then it is output as A-phase and B-phase initial incremental pulses (90° phase-difference pulses).
The output operation is the same as for an ordinary incremental encoder (90° phase-difference pulses).
