AKD

Digital servo amplifiers AKD are designed for driving of rotary and linear synchronous servomotors. Servo amplifiers 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 servo amplifiers AKD are designed to be easily connected to different control systems, because of this the servo amplifiers 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 servo amplifiers

EtherCAT, CANopen, Profinet or Ethernet IP communication interface
Service channel Modbus/TCP (used for parameter setting)
Analog input +/-10V (16 bits)
Analog 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
HDSL (single-turn or multi-turn)
EnDat 2.2 (single-turn or multi-turn)
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)
