(HSD108+20*(N-1)) will change.
● when the motor enabled, it can clear the parameters in table 1 and 2.
● there are four methods to change the present position:
① return to origin through (SM2014+20*(N-1)), (SM2015+20*(N-1)), the present
position will change.
② when PLC stop, modify the target position feedback pulse numbers (+20*(N-1)), the
present position will change
③ when PLC is running, execute MOWRITE can modify (HSD104+20*(N-1)), the
present position will change.
④ when PLC is running, servo does not enable, the servo position is chagned by
external force, register (HSD104+20*(N-1)) will change. When the servo enabled, this value is
valid.
