5.2.5 Fine Machine Zero

Becasue the G54 to G59 Coordiantes are all refers to Mach (Machine) Coordinate,every time the users
start the controller,should check the origin position and find the machine zero of each axis to confirm the
position.
5.2.5.1

All axis Find Machine Zero

Conditions:
• Controller is in READY status;
• The screen go to "Main page".
Operation:
• Press the key
• all the axis move to the limited switch position on the order;
• after homing,each axis moves away from home switch for a certain distance.(can be set at parameter
setting);
• By default the Homing Sequence is Z-XY-A
5.2.5.2

Single axis Find Machine Zero

Conditions:
• Controller is in READY status;
• The screen go to "Main page".
Operation (Take Example as X axis):
• Press the key
• after homing,X axis moves away from home switch for a certain distance.(Parameter setting).
Notice:
When homing(GoTO find Mach Zero),the soft-limit is invalid.The soft limit can only become effective
after the machine coordination built up.
The related Index No. is 49/50/51-55/60-61/64-67/56-59/83-86/116-119.
