6) PHASE A/B (x4)
Count operation is performed in case of the increase/decrease in A phase input pulse and the increase/decrease in B
phase; and add operation is performed when the phase of A phase is input ahead of B phase; and subtraction operation is
performed when the phase of B phase is input ahead of A phase.
(e) Maximum and minimum values of encoder
1) The range of the encoder value is set to the maximum and minimum values of encoder when counting the input pulse from
the encoder signal of servo drive or manual pulse generator and indicating it to encoder value.
2) Operations are as shown in the figure below.
- In case of the increase in the encoder value
- In case of the decrease in the encoder value
