8.16 ACTA 3000
The ACTA 3000 device enables calibration of the torque transducer for the spindles of your system using
the ACTA test equipment from Atlas Copco. One device enables calibration of all spindles in the station.
Add the device to the Station TC and make the physical connection of the ACTA unit to this TC.
Use Name to specify the name of the device.
Port specifies which physical communication port that should be used. Port 2 is default and should be
used for the standard cables.
You can control whether or not cycles can be started from the PowerMACS PLC or the Test Bolts form
using the PLC System Globals Station variables ACTA_ACTIVE and DISBALE_ACTA.
The PLC program created by default (when no GM DeviceNet device is used) blocks out starts from the
PowerMACS PLC and the Test Bolts form.
The calibration can be run in two different modes, controlled by the ACTA or controlled by the TC.
Controlled by ACTA
If the calibration is controlled by the ACTA the cycles are started from the ACTA unit. In the ACTA unit you
have to specify the spindle and the mode number that shall be used. It is only this spindle that will run.
If mode 0 is selected a special program adapted to the QRTT equipment is used for the calibration. With
this program both the torque and angles can be verified and calibrated.
