4.1.1.4 Encoder
The position encoder of this controller supports 9 kinds of digital
signal input formats as described below.
Table 4-1: Encoder input format
CAUTION
Please set up the position encoder before doing motion control.
This is especially true for analog output type closed-loop control
as invalid setup may lead to motor burst.
NOTE NOTE
You may set up and test your controller with MotionCreatoPro
2 software. You can check this by manually spinning the motor
(or move the workbench) and verify the encoder signal from
motor or linear scale to the controller.
