General Information

In order to be able to process the sensor data of the spindle in the control, the sensors must first
be connected to I/O modules and transferred to the PLC via fieldbus (PROFIBUS DP or
PROFINET I/O).
For a spindle with SMI 24 (Weiss spindle), the sensor data are transferred to the drive using
DRIVE-CLiQ and are available there in drive parameters. When using cyclic drive telegram
139, sensor data from the drive are transferred to the control. They are then available there in
the following system data:
● System variable
● OPI variables
● NC/PLC interface signals

Comment
; S3500 is greater than MD35110 of the 2nd gear stage. The
2nd gear stage is selected.
; Spindle is stopped, S0 does not request a gear stage
change (special handling, S0).
; S5 is less than MD35120 of the 1st gear stage. The 1st
gear stage is selected.
