FP2 Positioning Unit Feedback Counter
13-5
Program
The following example program compares the count of the output pulses with the count of the feedback
pulses at the E point control and makes the deceleration stop if the count is out of the allowable range.
For the pulse count of the feedback counter, read the values in H10F, H10E for the 1st. axis, in H11F,
H11E for the 2nd. axis, stored in the shared memory.
The feedback counter is available for every axis.
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.
Please note that the counter value will be cleared when the home return is completed or when the Error
clear flag (Y_F) is ON.
