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.
