Repair SERVOSTAR 446-M Servo Drive ( Riparazione / Pемонт / Reparatur / Service)


The SERVOSTAR 400 series of digital servo amplifiers is a mature multi-axes (up to 8 axes) servo system that delivers maximum performance in minimum space and at minimum cost. The system is modular, allowing the customer to easily develop the application of any complexity. Some of the features of the SERVOSTAR 400 are:

  • Power supply and regeneration circuit integrated in the master (first axis) – stand-alone operation;
  • Up to 7 extension axes at one master;
  • DIN rails mount;
  • Internal Bus connection between modules;
  • Single interface for control;
  • Can be used for synchronous servomotors, linear motors and asynchronous motors;
  • Resolver and encoder feedback;
  • Controls for the motor brake;
  • Fully programmable via RS232 interface.


SERVOSTAR 446-M is one Master Unit which has the following electrical characteristics:

  • Rated supply voltage: 3 phase 230-400 V AC;
  • Rated installed power for S1 operation: 12 kVA;
  • Rated DC link voltage: 310 – 560 V;
  • Rated output current: 6 A;
  • Peak output current: 12 A;
  • Continuous power regeneration circuit: 40 W.


The unit has the following features:

  • High resolution sine-cosine encoder feedback;
  • User interface  by the LED-Display and keyboard;
  • Optional protocols supported: EtherCAT, PROFIBUS and SERCOS;
  • Digital current controller;
  • Full programmable digital speed controller;
  • Integral position controller;
  • Integrated pulse direction interface;
  • 4 programmable digital inputs;


Our laboratory offer free diagnosis for all types of electronic boards. We consider that unless we have identified the root cause of the malfunction we cannot estimate the appropriate repair cost. Usually, repairing costs do not exceed 30% of the price for a new motherboard or equipment.



Our service department ensures complex repairing processes for electronic components. The tasks are professionally administered and executed by well-trained engineers who can perform correct diagnosis and repairing from simple boards to multi-layer PCB (Printed Circuit Boards).


The repairing procedure includes:

  • in-depth cleaning of boards
  • rebuilding damaged circuits
  • building work schemes partly or fully, if necessary
  • circuit analysis in order to uncover flaws
  • replacing damaged components
  • preventive replacement for components that could cause further damage
  • software/firmware/bios backup
  • delivery towards testing area


Components inventory

The components are being replaced with spare parts belonging to our inventories, but there are cases when it is necessary to import several spare parts directly from the manufacturer/distributor. Our past experience has given us the possibility to build up good communication means with European, Asian and American manufacturers; therefore we also give you the benefit that, in accordance with our contract, we can cover any need of component required by the repair process.


Optional services

On demand, we also provide the following services:

  •  Delivering the equipments from/to your address
  •  Transportation can be made possible by using any of the following companies: DHL, UPS.
