With the DARC 2-Compact servo controller, powerful single-axis applications can be implemented particularly economically.
It consists of a combination of supply module and axis controller module.

DARC 2 Compact with slot
Various function modules can be used in the DARC 2-Compact with slot, depending on the application.
There are currently 5 different slots available:

• • Standard insert DE-STA
    This slot provides a 7-segment display for operating and error status.
  • Safety relay module DE-SIR
    This insert is required to shut down the axes if the DC link voltage is not to be switched off. The 7-segment display is also available.
  • Incremental encoder insert DE-INC
    This insert is required if a direct measurement in the machine via a second encoder is required. The 7-segment display is also available.
  • Resolver module DE-RES
    This slot enables the use of a resolver instead of a high-resolution encoder as motor feedback. The 7-segment display is also available.
  • Absolute encoder slide-in DE-SSI
    This optional plug-in functions in the axis controller as an encoder interface, with regard to absolute value encoders for position control on a 2nd encoder or as a measuring system.

At least one slot must be plugged in!
Without an insert, the axis is stopped and cannot be moved!

The slide-in units are automatically recognized by the axis controller after switching on!

The fieldbus connection is not required for control via the binary inputs.

Fast I/O control without fieldbus connection
You can store 64 complete traversing records in the DARC 2-Compact. If necessary, the corresponding traversing block (via the digital inputs)
be started. You can create these traversing blocks on an external PC and load them into the DARC 2-Compact controller via the integrated serial interface.

Control via fieldbus connection
A CAN Open interface is included in the DARC 2-Compact controller.
In this operating mode, the DARC 2-Compact controller receives its work instructions (including parameters) from a higher-level master computer system (SPS / PLC).
All information and data for the implementation of these work instructions are stored centrally on the “master computer system”.

Other properties:

• • • 2KVA power
    • Field-oriented control for asynchronous and synchronous motors
    • Homing
    • Integrated high-resolution encoder interface for speed and position detection.
      Direct connection of the encoder feedback via system cable (pluggable).
      In conjunction with a high-resolution motor feedback system, a
      high positioning accuracy and high load rigidity guaranteed.
    • Relative and absolute positioning
    • Integrated application function. Control is via the I/Os.
    • Integrated mains filter (class A)
    • Integrated braking resistor
      In many applications, no external braking resistor is required.
    • Servo operation with encoder feedback or frequency converter operation without encoder feedback possible (e.g. frequency converter operation up to 24,000 rpm for spindle operation).
    • 16 inputs (24V) and 8 freely configurable inputs/outputs integrated
    • Fieldbus interface according to CAN-Open
    • Separate 24V feed For secure communication with the fieldbus, even if the power supply fails.
    • Support of direct drives (linear motor)
