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 plug-in units can be used in the DARC 2-Compact with slot, depending on the application.
There are currently 5 different plug-in units available:

• • Standard plug-in unit DE-STA
    This plug-in unit provides a 7-segment display for operating and error status.
  • Safety relay plug-in unit DE-SIR
    This plug-in unit is required to stop the axes if the DC link voltage is not to be switched off. The 7-segment display is also available.
  • Incremental encoder plug-in unit DE-INC
    This plug-in unit is required if direct measurement in the machine via a second encoder is required. The 7-segment display is also available.
  • Resolver plug-in unit DE-RES
    This plug-in unit enables the use of a resolver instead of a high-resolution encoder as motor feedback. The 7-segment display is also available.
  • Absolute encoder plug-in unit DE-SSI
    This optional plug-in unit acts as an encoder interface in the axis controller, with regard to absolute 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 travel sets in the DARC 2-Compact. If required, the corresponding movement set can be started (via the digital inputs)
. 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
The DARC 2-Compact controller is equipped with a CAN Open interface.
In this operating mode, the DARC 2-Compact controller receives its operating instructions (including parameters) from a higher-level master computer system (PLC).
All information and data for implementing these operating instructions are stored centrally on the “master computer system”.

Other properties:

• • • 2KVA power
    • Field-oriented control for asynchronous and synchronous motors
    • Homing
    • High-resolution encoder interface for speed and position detection integrated.
      Direct connection of the encoder feedback via system cable (pluggable).
      In conjunction with a high-resolution motor feedback system,
      high positioning accuracy and high load rigidity are 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)
