The ROI A10-10 axis interface allows you to control a position-controlled axis
by means of an actual value system and an analog setpoint output. It sends
the encoder actual value to the controller and generates an analog output
voltage from the speed setpoint of the PLC/CNC. It also has a number of
digital inputs/outputs that are directly sent to or controlled by the PLC/CNC.
The axis interface has no intelligence of its own (e.g. position controller or
similar). It merely provides interfaces.
The RIO A10-10 is designed to be used directly on the PLC, because the
standard field buses demonstrate non-deterministic behaviour. The SCHLEICHER
microLine and XCx controllers are suitable.
Interfaces:
• Incremental/absolute encoder interface (similar to RS422).
If an incremental encoder is connected, the encoder actual value supplied
to the controller is generated by an up/down counter counting the encoder
pulses. If an absolute value encoder is connected, the encoder supplies the
actual value directly.
• Inputs for limit switch, reference cam, servo amplifier ready (digital, 24 V)
• Output for controller enable (digital, 24 V)
• Analog output (±10 V).
A corresponding analog output voltage is generated from the speed
setpoint supplied by the controller.
• Freely configurable combination input/output (digital, 24 V)
The module possesses limited functionalities of its own. The analog output
and the controller enable can be shut down without involving the PLC/CNC.
You can set the events (ready, limit switch, cable break, etc.) that lead to
shutdown. The watchdog function deactivates the module if the internal bus is
interrupted for more than 80 ms; all outputs are shut down. The encoder
actual value remains valid and the incremental encoder signals continue to
be processed.
You can alter the module configuration via the controller:
• Encoder type (incremental/absolute)
• Zero signal processing
• Code, data length and clock rate of actual value encoder
• Delete actual value
• Monitor ready, limit switch and cable break
