Overview
Either of the following types of pulse input signals can be input to the unit:
• Pulse trains from normal incremental encoders, etc.
• Encoder output data (Ex: OMRON's W series, etc.) of servo drivers with
absolute encoders (multi-turns absolute encoders)
The following explains the functions that are compatible with the latter, servo
drivers with absolute encoders.
Note
As for the pulse train inputs from normal incremental encoders, etc., the pulse
input functions are the same as the ones of the model CS1W-HCP22(-V1)/
HCA22(-V1). Refer to
Pulse Inputs
on page 126 for details.
To input the encoder output data from a servo driver with an absolute encoder
to the unit (CS1W-HCA12-V1), the SEN output signal from the unit has to be
connected to the servo driver. When starting an operation, the amount of
multi-turns (to phase A as serial data) and the initial incremental pulse (to
phase A/B as pulse) are input once as the absolute position information.
After that, the position data during operations are input with the phase differ-
ence input (using normal counter functions).
Using a servo driver with an absolute encoder enables the controlled opera-
tion to be started from the position at turning on the power without performing
any origin searches.
