Mode 2:
Diagram A:
Positive limit switch = OFF
1. Move in
positive direction
at
high velocity
until
positive limit switch valid.
2. Move in
negative direction
at
low velocity
and stops
after positive limit switch
and
first encoder Z-signal valid
Diagram B:
Positive limit switch = ON
1. Start to move at
positive limit switch position
in
negative
direction
at
high velocity
until
positive limit switch invalid.
2. Move in
positive direction
at
high velocity
until
positive limit switch valid.
3. Move in
negative direction
at
low velocity
and stops
after positive limit switch
and
first encoder Z-signal valid
If the negative 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.

Mode 3:
Diagram A:
Homing switch = OFF
1. Move in
positive direction
at
high velocity
until
homing switch valid.
2. Move in

until
after
homing switch.
2. Move in
positive direction
at
high velocity
until
homing switch valid.
3. Move in
negative direction
at
low velocity
and stops
after homing switch
and
