CAX1122 Module

CAX1122 is an open frame CanBus module with CanOpen protocol mountable on a standard DIN rail for axis control.

By reading the axis position with an incremental optical encoder, or with a potentiometer, it can closed loop control the axis position, and provide an analog speed reference signal.

In both cases (encoder, and potentiometric) the module direcly powers the transducer with a stabilized, short-circuit protected recerence voltage.

The controlled axis can be a brushless motor driven axis, in this case the analog reference signal must be connected to a power driver input, or an hydraulic axis, in this case the analog reference signal must be connected to the input of an amplification board that drives the coil of a servovalve or a quality proportional valve.

In case of a power driver a second analog signal is available to adjust an optional current limiting device. Also for this latter case 4 optocoupled ON/OFF signals are available with the following meaning:

5 groups of spring-cage connectors are provided:

• 3 points of which two are for 24 V power supply connection, and one is for ground connection
• 1 four indvidually exctractable points group with the following meaning:
  • Potentiometer power supply positive pole;
  • Differential voltage signal input negative pole
  • Differential voltage signal input positive pole / Potentiometric cursor
  • 0V potentiometer referce
• 2 two points groups for the output signal. Each indvidually exctractable two point group has the following purpose:
  • Output signal, relative to the 0 V reference;
  • 0 V reference
• 8 spring cage points for digital optocoupled inputs, and output connections;
• 6 points for the CanBus line (CANH, CANL, and GND_CAN input, CANH, CANL, and GND_CAN output)

One D type female connector is available for encoder connection.
