The CNC sets these signals high to tell the PLC that the machine reference search has been made
already. The CNC forces a home search on an axis by setting its mark low.
The marks are set low in the following instances:
• On CNC power-up.
• After executing the sequence [SHIFT] [RESET].
• When the feedback is direct through the axes board and a feedback alarm occurs.
• When losing feedback count via Sercos due to broken communication. Difference greater than
10 microns (0.00039 inches) or 0.01º
• When modifying certain machine parameters; for example, number of axes.
In all these cases, a home search must be carried out so the signal is set back high.
DRSTAF1 (M5603) DRSTAS1 (M5604) DRSTAF2 (M5653) DRSTAS2 (M5654)
DRSTAF3 (M5703) DRSTAS3 (M5704) DRSTAF4 (M5753) DRSTAS4 (M5754)
DRSTAF5 (M5803) DRSTAS5 (M5804) DRSTAF6 (M5853) DRSTAS6 (M5854)
DRSTAF7 (M5903) DRSTAS7 (M5904) DRSTAF8 (M6603) DRSTAS8 (M6604)
DRSTAF9 (M6653) DRSTAS9 (M6654)
The CNC uses these signals when communicating with the drive via Sercos or via CAN and indicate
the status of the drive.
When an internal error occurs at the drive, the DRSTAF* and DRSTAS* signals are set low (logic
level low).
MAXDIFF1 (M5605) MAXDIFF2 (M5655) MAXDIFF3 (M5705) MAXDIFF4 (M5755)
MAXDIFF5 (M5805) MAXDIFF6 (M5855) MAXDIFF7 (M5905)
These marks are activated when the position difference between master and slave is not
compensated because the coordinate difference is greater than the value of axis parameter
MAXDIFF (P97). This can happen after homing both axes of a Gantry pair.
This way, the PLC can issue a warning indicating that the position difference between the master
and the slave has not been compensated for.
ANT1 (M5606) ANT2 (M5656) ANT3 (M5706) ANT4 (M5756)
ANT5 (M5806) ANT6 (M5856) ANT7 (M5906)
These signals are related to axis parameters MINMOVE (P54).
If the axis move is smaller than the value indicated by this axis parameter MINMOVE (P54), the
corresponding axis logic output "ANT1 thru "ANT7" goes high.
INPOS1 (M5607) INPOS2 (M5657) INPOS3 (M5707) INPOS4 (M5757)
INPOS5 (M5807) INPOS6 (M5857) INPOS7 (M5907)
The CNC sets these signals high to tell the PLC that the corresponding axis is in position.
There is also the general logic output INPOS in which the CNC indicates to the PLC that all the axes
have reached their position.
DRSTAF* DRSTAS*
Actuating the main switch of the electrical cabinet supplies 24 Vdc to the
drive.
The drive runs an internal test.
If correct, it activates the output "System OK". 0 0
From that moment on, the power supply must be turned on.
When there is power at the drive bus, it is ready to output torque. 0 1
To do that, activate the "drive enable" and "speed enable" inputs. 1 0
Once the "drive enable" and "speed enable" are activated, the drive is
running properly. 1 1
