To overhaul its servo-driven rotary indexing table, the Compact Basic Machine (CGM) that produces filigree mechanics, PIA Automation wanted a solution that not only monitored the movements safely but at the same time enabled higher cycle counts. The rotary indexing tables now run more safely, more efficiently and with greater flexibility with the drive solution from Pilz.
Productivity boost for rotary indexing tables
Higher cycle counts due to safe drive
The CGM rotary indexing table is a servo-driven, modular and flexible fully automatic machine. A driven axis is responsible for the movement of the rotary table as well as the vertical and horizontal stroke. The motion control system PMCprimo DriveP specifies the movements and is responsible for the whole motion and safety management of the servo axes, along with three safety cards PMCprotego S for motion monitoring. Today the new solution enables up to 72 cycles per minute, in contrast to the previous 50. It’s also more flexible: to change product, the operator simply selects another program with the required curve profile and in no time the plant is available for another task. Additional benefit: in the event of an emergency stop the drive axes always retain their mechanical cohesion, i.e. the axes always operate synchronously and production can restart without delay.
The benefits at a glance:
- Short cycle times thanks to a powerful real-time EtherCAT master interface
- Integrated development environment for PLC in accordance with the IEC 61131-3 standard for application development in industrial automation
- The safety functions of the PMCprotego S are designed up to Performance Level PL e, independent of the motor and encoder type
“Pilz worked in close cooperation with our engineering department, managing and implementing the whole modification in word and deed with a high level of competence. The Pilz solution is convincing not least because of the integration of EtherCAT Master, PROFINET Slave and the connection to a higher level system, which measures the spindles’ performance”
