Limit switch Z-signal mode
Mode 1:
Diagram A:
Negative limit switch = OFF
1. Move in
negative direction
at
high velocity
until
negative limit switch valid.
2. Move in
positive direction
at
low velocity
and stops
after negative limit switch
and
first encoder Z-signal valid
Diagram B:
Negative limit switch = ON
1. Start to move at
negative limit switch position
in
positive
direction
at
high velocity
until
negative limit switch invalid.
2. Move in
negative direction
at
high velocity
until
negative limit switch valid.
3. Move in
positive direction
at
low velocity
and stops
after negative limit switch
and
first encoder Z-signal valid
If the positive limit signal is valid during the homing process, the status word (6041h) bit 13
will be valid, indicating homing error and the motor will stop immediately.
