7-3 Description of Functions
Note: The forward run (run) and reverse run (RP) cannot be distinguished during the position control mode. The CCL will
be forward run and the RCCL will be reverse run even when RR is set ON.

The function is effective under the following conditions.
Condition 1: The initialization value of deviation counter switches from positive to negative
Carry out one addition/reduction for the setting value of F8103
Example) When the initialization value switches from 200 to -300,
F8103=1000: the initialization value of the deviation counter =-300+1000=700
F8103=-500: the initialization value of the deviation counter =-300-500=-800
Condition 2: The initialization value of deviation counter switches from negative to positive
Carry out one addition/reduction after reversing the signs for the setting value of F8103
Example) When the initialization value switches from -400 to 200,
F8103=500: the initialization value of the deviation counter =200-500=-300
F8103=-200: the initialization value of the deviation counter =200+200=400
Condition 3: When the polarity of the deviation counter doesn‘t change,
The addition/reduction is not required for the setting of F8103.
