LOGIC CNC INPUTS AND OUTPUTS
SOFT: V02.2X
General logic outputs
SYNSPEED (M5560)
Indicates that the spindles are synchronized in speed (set high). In other words, that the second
spindle turns at the same speed as the main spindle.
It goes low when the following error between them exceeds the maximum allowed by spindle
parameter SYNSPEOF (P54).
SYNCHRON (M5561)
Indicates that the G77S function is currently selected (spindle synchronization).
SERPLCAC (M5562)
It is used in the data exchange, via Sercos between the CNC and the drives.
The CNC sets this signal high to "tell" the PLC that the requested change of parameter sets and
gear ratios is in progress.
While this mark is on, no other change may be requested because the command would be lost.
RETRACT (M5567)
During the drilling, tapping and rigid tapping cycles of the mill model CNC, it is now possible to
withdraw the tool to the starting plane and, once there, stop the spindle.
Once the retraction is completed, the user may finish the hole, go to the next hole or go into tool
inspection.
General logic output RETRACT (M5567) is activated when the stop is completed and it is canceled
when completing the retraction of the drilling or mill type threading operation.
When retracting the axes on the lathe model, general logic output RETRACT (M5567) is activated
when pressing [STOP] and the CNC starts retracting. This mark will stay active until the withdrawal
distances set in G233 are reached.
TMINEM (M5569)
Mark activated when the CNC detects an error during tool change. This mark stays memorized until
it is canceled by the RESTMEM mark or with the option [REMOVE ERROR] shown in the error
message.
READEND (M5507)
CNC output that indicates that the message received is in the buffer.
Default value 0.
READRDY (M5571)
CNC output that indicates whether the READ commands may be received or not.
Value Meaning
0 The execution of the RCV instruction begins.
1 It indicates that the process started by the RCV instruction has finished and that the
message is in the buffer.
Value Meaning
0 It indicates that no READ commands may be received.
1 It indicates that READ commands may be received.
