Module 9123 Traversing the reference marks of PLC axes
Traverse the reference marks as for NC axes.
n
You can use the same procedure to traverse a reference mark for PLC axes
as for NC axes. Use Module 9123 only if no conventional procedure is
possible.
n
Module 9123 moves the axis in the given direction until the reference mark
has been traversed. The axis stops next to the reference mark, offset by the
braking path.
Call:
PS
B/W/D/K <Axis>
0 to 8 correspond to axes 1 to 9
PS
B/W/D/K <Feed rate>
Input unit: [mm/min]
PS
B/W/D/K <Mode>
Bit 0: Direction of traverse
0: Positive
1: Negative
CM
9123
PL
B/W/D
<Error code>
0: No error. Positioning was started.
1: Axis does not exist
2: Not a PLC axis
3: Axis is already being positioned
5: Programmed axis not in closed loop
6: Feed rate not permitted
Module 9124 Feed rate override for PLC axis
Enters the feed rate override for one PLC axis.
Conditions:
n
After interruption of a PLC program, the override value is set to 100%.
n
When a positioning is started, the last defined override value is in effect.
n
The override value can also be changed during a positioning movement.
Call:
PS
B/W/D/K <Axis>
0 to 8 correspond to axes 1 to 9
PS
B/W/D/K <Override>
Input unit: 0 to 10 000, corresponds to 0 to 100%
in 0.01% steps
CM
9124
PL
B/W/D
<Error code>
0: No error, override value was set
1: Axis does not exist
2: Not a PLC axis
3: Override value incorrect
