Diagram A: Homing switch & negative limit switch = OFF
1. Move in negative direction at high velocity until homing switch valid.
2. Move in positive 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 positive direction at high velocity until
after homing switch.
2. Move in negative direction at high velocity until homing switch valid.
3. Move in positive 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 the negative limit switch valid.
2. Move in positive direction at high velocity until homing switch invalid.
3. Move in negative direction at high velocity until homing switch valid.
4. Move in positive 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.
