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