13.2 Feedback Counter Functions
-The feedback counter can be used as a general-purpose counter as 2-phase input, Direction distinction
input or Individual input.
- The feedback counter uses the contact which is the same as the one for the pulse input signal.
Accordingly, it can not function together with the pulser input operation.
-The feedback counter is available for each axis.
Please note that the counter value is cleared when the home return is completed or when the Error
clear flag (Y_F) is ON. A special attention is required when using the feedback counter as a general-
purpose high-speed counter.
- When counting the 2-phase input such as the input from the encoder, set the pulse input transfer
multiple to “4 multiple setting” (x 4) or “2 multiple setting” (x 2) using the control code to prevent
counting error.
The pulse count value for the feedback counter is stored in the addresses below;
