Options available:
• APPROACH_NEGATIVE_PASSIVE(0)
Homing with approach to zero mark in negative direction
• APPROACH_POSITIVE_PASSIVE(1)
Homing with approach to zero mark in positive direction
• EDGE_POS_SIDE_NEG_PASSIVE(2)
Homing with approach to BERO in positive direction
• EDGE_POS_SIDE_POS_PASSIVE(3)
Homing with approach to Bero in negative direction
• EDGE_NEG_SIDE_NEG_PASSIVE(4)
Homing with motion off the BERO in positive direction
• EDGE_NEG_SIDE_POS_PASSIVE(5)
Homing with motion off the Bero in negative direction
• ACTUAL_DIRECTION_PASSIVE(6)
Homing with the next edge at BERO or zero mark
The selection of the approach direction depends on the homing mode. The table
below shows the relationship between the approach direction and the homing
mode:
