16.9 Spindle with SMI 24 (Weiss spindle)
16.9.1 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
Requirement
• The spindle is connected to the drive via Sensor Module SMI 24 using DRIVE-CLiQ.
• Drive telegram 139 is configured for the spindle.
16.9.2 Sensor data
Sensors in the spindle motor
The spindle sensors provide information about the clamping device and the angular position of the motor shaft:
• Analog sensor S1: Clamped state
Voltage value in the range from 0 - 10 V depending on the position of the draw bar.
• Digital sensor S4: Piston end position
- 0 = piston not in position
- 1 = piston is in position, i.e. piston is free to move
• Digital sensor S5: Angular position of the motor shaft
- 0 = motor shaft not aligned
- 1 = motor shaft is in position (precondition: The spindle is stationary)
Note
Drive telegram 139
In principle, a spindle with Sensor Module SMI 24 can also be operated with another drive
telegram. However, sensor data is only transferred to the control using drive telegram
139.
