5. Controlling the SPC200

Outputs
Function Description
MC_B
(motion complete) MC output for program B
(like MC_A, but for program B)
MC_A
(motion complete) MC output for program A (see also chapter 7.4, NC command G61)
1−signal at this output indicates that a positioning task from program A has
been concluded. When the positioning task has been completed, an MC signal
will also be sent if the axis is no longer at the programmed nominal position
(e.g. because of failure of the compressed air supply, unstable control, etc.).
0−signal indicates that a positioning task is being processed.
If there is to be evaluation of the MC signal by the PLC: In the case of positionĆ
ing tasks which follow directly one after the other, the MC signal may be too
brief to be evaluated by the PLC. The signal can be lengthened between the
positioning commands with the aid of NC command G04.
The MC output is not reset when a positioning task is carried out within the
positioning tolerance (stroke
< positioning tolerance)
A separate MC signal is generated internally in the SPC200 for each axis
addressed. These MC signals are AND−linked internally (see Fig. 5/5).
SYNC_OB Synchronization input for program B
(like SYNC_OA, but for program B)
SYNC_OA Synchronization output for program A
If there is a 1−signal at the SYNC_IA input during a Programmed Stop (comĆ
mand M00), a 1−signal at this output will indicate the readiness to process the
next NC record.
If there is a negative edge at the SYNC_IA input, output SYNC_OA will be reset
and the next NC record will be processed (see Fig. 5/6).
READY System ready to operate
This output supplies a 1−signal if the system is ready to operate.
A 0−signal at this output indicates that there is a system fault or positioning
fault or that there is no ENABLE signal.
