6.8 Encoder Divided Pulse Output
6.8.1 Encoder Divided Pulse Output Signals
 Precautions When Using a Linear Incremental Encoder from Magnes-
cale Co., Ltd.
 Encoder Divided Phase-C Pulse Output Selection
You can also output the encoder's phase-C pulse for reverse movement. To do so, set Pn081
to n.1.
Pn081
Important
Observe the following precaution if you set Pn081 to n.0 (Output phase-C pulses only in
the forward direction).
When a linear incremental encoder from Magnescale Co., Ltd. is used, the count direction of
the encoder determines how the phase-C pulse (CN1-19 and CN1-20) is output.
Note: The count direction (up or down) of the linear encoder determines whether a phase-C pulse is output. The
output of the pulse does not depend on the setting of the movement direction (Pn000 = n.1).

Precautions on Setting the Phase-C Pulse Output Selection (Pn081 = n.X)
• If you set Pn081 to n.1 (Output phase-C pulses in both the forward and reverse direc-
tions), the width of the phase-C pulse output may be narrower than the width of the phase-A
pulse.
• There is a difference of 1/8th of the scale pitch in the phase-C detection position for the
encoder's phase-C pulse output position between when Pn081 = n.X is set to 0 (Output
phase-C pulses only in the forward direction) and when it is set to 1 (Output phase-C pulses in
both the forward and reverse directions).
