KEY POINTS
The pulser input operation and feedback pulse count of the unit uses the same pulse
input terminal. Therefore, select either one of them.
- The use of a twisted-pair cable is recommended.
- In the case of counting 2-phase inputs, such as encoder inputs, use a control code
and set the pulse input count to x4 or x2 for the prevention of counting errors.
