A=1: Reverse homing and CWL limit input point is regarded as a rough reference “Home”. When home
is in position, CWL will turn into limit input function. If trigger CWL afterward, the limit alarm will
occur. When use limit input point as a rough reference “Home”, we recommend users to set B=0,
i.e. return to find Z-phase pulse during homing and regard Z-phase pulse as a precise
mechanical “Home”.
A=2: Forward homing and ORGP (Reference “Home” sensor) is regarded as a reference “Home”. At
this time, users can set B=0, i.e. return to find Z-phase pulse during homing and regard Z-phase
pulse as a precise mechanical “Home” or set B=1, i.e. do not return and go forward to find
Z-phase pulse and regard Z-phase pulse as a precise mechanical “Home”. If users do not use
Z-phase pulse as mechanical “Home”, users can set the rising-edge of ORGP as the mechanical
“Home” (B=2).
A=3: Reverse homing and ORGP (Reference “Home” sensor) is regarded as a reference “Home”. At
this time, users can set B=0, i.e. return to find Z-phase pulse during homing and regard Z-phase
pulse as a precise mechanical “Home” or set B=1, i.e. do not return and go forward to find
Z-phase pulse and regard Z-phase pulse as a precise mechanical “Home”. If users do not use
Z-phase pulse as mechanical “Home”, users can set the rising-edge of ORGP as the mechanical
“Home” (B=2).
A=4: Forward-finding Z-phase pulse “Home”. This function is usually used when the servo motor runs
within one revolution. The servo motor can not be connected to any external sensor switch at this
time.
A=5: Reverse-finding Z-phase pulse “Home”. This function is usually used when the servo motor runs
within one revolution. The servo motor can not be connected to any external sensor switch at this
time.
(2) B: Homing Moving Method
B=0: After find reference “Home” (after homing completed), the servo motor returns in 2nd step speed
to find the nearest Z-phase pulse as the mechanical “Home”.
B=1: After find reference “Home” (after homing completed), the servo motor does not return and
continue to go forward in 2nd step speed to find the nearest Z-phase pulse as the mechanical
“Home”.
B=2: When A=2 and A=3, find the rising-edge of sensor ORGP as the mechanical “Home” and stop
according to deceleration time. When A=4 and A=5, stop according to deceleration time after find
Z-phase pulse.
(3) C: Homing Enable Setting
There are two settings for enabling homing function. One is automatically enable homing function and
the other is enable homing function by input contact (SHOM).
C=0: Disable homing function.
When C is set to 0, it indicates that homing function is disabled no matter what other parameter
