 TGA-24

TGA-24 controllers are designed to operate AC synchronous servomotors of up to 150W. A power supply of 24VDC allows the servo amplifiers to be used in applications, where it is not possible to supply a voltage of 230/400V AC e.g. in mobile equipment or in environments that require safe voltages to be used.

A high-performance processor ensures not only high quality, accuracy, control and dynamics of the servomotor but also ensures a selection of user functions that allow the universal utilization of the servomotor.

A digital current loop (current measuring, vector control, position measuring from resolver) is cauculated every 62,5μs, speed loop is cauculated every 250μs, position is cauculated every 1ms.

Operating modes

The TGA-24 servo amplifier can operate in the following modes:

  • Torque control
  • Speed control
  • Absolute positioning
  • Relative positioning
  • Pulse and direction signals control (stepper-motor control)
  • Electronic gearing and Continuous control via CAN-BUS

Communication

The TGA-24 servo amplifier is able to communicate via the RS232 serial interface, RS485 (RS422) – protocol MODBUS and via CAN BUS.

Inputs / outputs

The TGA-24 is equipped with 8 digital inputs, 4 digital outputs, 1 analogue input (+/-10V or 0-5V or 0-10V), 2 fast configurable count inputs/outputs.

Parameter settings, status monitoring

The SETUP program (included in the delivery) allows parameter settings and status monitoring using a PC. The program SETUP is executable under Windows operating systems and communicates with the TGA-24 servo amplifier via the RS232 serial interface.

Control

The TGA-24 servo amplifier can be controlled by

  • Analog voltage – torque or speed
  • Stepper-motor signals (pulse and direction)
  • Digital inputs – start of programmable position or speed profiles
  • Digital control by serial interface RS232 (422/485) or by CAN-BUS (torque, speed, position profiles etc.)

Firmware – customized

We offer customized firmware madefor special applications. The TGA-24 Firmware Loader is a program that allows new firmware to be uploaded to the TGA-24 servo amplifier via the RS232 serial interface. The firmware upload takes several seconds.

Mechanical design

The L-profile allows variable mounting of the servo amplifier to the switchboard or directly to the machine.
