Digital servoamplifiers AKD are designed for driving of rotary and linear synchronous servomotors. Servoamplifiers are equipped with multiple inputs for communication with many types of positioning sensors. This gives us the possibility to find an optimum priced solution of a used feedback sensor and of a servomotor application.

Digital servoamplifiers AKD are designed to be easily connected to different control systems, because of this the servoamplifiers can be used in many applications. In relation to the application and control system used, it is possible to utilize the integrated motion functions or to use only the basic functions of control loops.

Controlling of AKD servoamplifiers

  • EtherCAT or CANopen communication interface
  • Service channel Modbus/TCP (used for parameter setting)
  • Analogue input +/-10V (16 bits)
  • Analogue output +/-10V (16 bits)
  • Digital control inputs (7) and outputs (2) – activation of programmed position profiles
  • Control signals for step motors „STEP“ and „DIRECTION“
  • Control in the electronic gearing mode

Feedbacks

  • Resolver
  • EnDAT (single-turn or multi-turn)
  • Hiperface (single-turn or multi-turn)
  • A sensor with sincos signals
  • An Incremental sensor with commutation signals.
  • The possibility to simultaneously connect two sensors (e.g. resolver and incremental sensor)

Performance specification

  • Digital current loop (0,67 μs), speed loop (62,5 μs) and position loop (125 μs) ensure high motion dynamics and repeatibility of demand motion tasks
  • Servoamplifiers AKD 3×400 V are equipped with anti-interference network filter
  • Control of the motors holding brake
  • Input (STO – Safe Torque Off) to block the reverse – SIL2 by IEC 61508
  • The versatility of using increases the wide spectrum of supply voltages 3×120 – 3×240 V for the 230V version and 3×240 – 3×480 V and CE, UL and cUL certification
  • Simple Grafical User Interface (GUI)-WorkBench is designated to expedite and streamline the user's experience with AKD. From easy application selection and reduced math, to a sleek six-channel scope. WorkBench also makes auto-tunning the AKD high-performance drive with TG motors very simple.
