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