TGZ digital servo amplifiers bring a new concept of digital servo amplifiers for multi-axis applications. TGZ include features of modern digital control, simple default functions that user can call in his own program, connection to fast digital communication interfaces, connection of modern digital feedback sensors, low dissipation of power components and unique cooling system.

Thanks to the use of these new technologies it was possible to optimize size, reduce number of pins in connectors and to implement two power units for controlling of two servomotors into the same space.

TGZ represent an economy, but a high-quality solution for controlling servomotors. TGZ-320 version is for connection of 320 VDC from power unit 1× 230 V / 320 VDC.

TGZ-320 servo amplifiers is equipped with three communication channels:

  • Ethernet 100/1000 Mb/s with UDP protocol, dedicated for parameters download, monitoring, testing but also for on-line control
  • CAN BUS protocol can be modified according to customer request
  • Ethernet 100/1000 Mb/s with selectable protocol, programmed in gate array and dedicated for connecting fast industrial interfaces for the real-time controlling. This interface is currently equipped
    with EtherCat protocol; based on customer request it can be modified also to another type of protocol.

Inputs, outputs

TGZ-320 servo amplifiers have implemented:

  • 2 analog inputs
  • 8 digital inputs
  • 6 digital outputs


TGZ-320 digital servo amplifiers support the following types of feedbacks:

  • Hiperface DSL – digital communication, sensors are manufactured with a resolution of 17 to 23 bits per turn, multi-turn version = 4096 turns. This is used on motors with one connector or cable.
  • EnDat 2.2 – digital communication, sensors are manufactured with a resolution of 18 to 25 bits per turn, multi-turn version (4096 turns).
  • SSI – encoders with synchronous serial interface.
  • BISS - encoders with BISS-C protocol.
  • Hall effect sensors
