Mitsubishi Electric shows a handling application with pressure control directly in the servo amplifiers, In addition, the application illustrates several features such as third-party motor control, precise direct-drive motors in interaction with robots and third-party motors, PLC CPU, motion CPU and robot CPU together on the automation platform "iQ Platform", Backward compatibility, as well as the connection and presentation of the entire system on a control panel of the GOT2000 series.
In the compact handling application, robots, servo motors and linear motors move workpieces made of different materials. In a first step, the material of the workpiece is determined automatically. For this purpose, the part is located in a shelf on an ordinary pressure sensor, whose signals are routed directly to the servo amplifier. A servomotor drives a pressure control axis that presses on the workpiece. Instead of the usual position, torque or speed, the servo motor is controlled via pressure control. Due to the specific rigidity of the respective material, the workpiece can be determined by the pressure.
All data such as pressure, speed, position or type of material determined during this process are displayed on the Mitsubishi Electric control panel of type GOT2000. For easy visualization of the products, the GOT has corresponding ready-made templates.
The pressure control uses one Servo amplifier type MR-J3-B, which is regulated by the SSCNET III network. The new generation MR-J4-B amplifiers are also connected to the same network. Amir Dehnavi, Product Manager for Servo Motion and L-Series at Mitsubishi Electric, emphasizes: "With the use of the two servo amplifiers, we want to demonstrate that all our components are backwards compatible and can be combined with each other according to the" plug and play "principle . "
Afterwards, the 70 axis handling system driven by the HP2 Weiss linear motor guides the workpiece to a rotary indexing table. "We offer a wide range of servomotors ourselves. However, with the help of our controllers and servocontrollers, we are also able to integrate special motors from other manufacturers, "explains Amir Dehnavi. The rotary indexing table is driven by a direct drive motor, which achieves high torques with high precision without mechanical losses. When the workpiece is in position, it takes the vertical Articulated of the type RV-4FL and sorts it into a waiting box. The entire system is backed up by the WS Controller that meets all common safety standards.
An integral part of the solution is the iQ Platform, on which the PLC CPU, Motion CPU and Robot CPU are located and communicate in real time. Possible applications of such a handling system can be found, for example, in the semiconductor or automotive industry, in assembly tasks or XY traversing tables and in packaging, textile and printing machines.
