Product Description:

The VT1610-3X-E1-4WS2EE1 is a plug-in servo amplifier card manufactured by Bosch Rexroth Indramat and positioned within the VT 1600 Servo Amplifiers series. Installed in a DIN-rail or rack back-plane, it receives process-level reference signals and produces regulated drive currents for proportional devices used in positioning, pressure, or flow control tasks. By translating millivolt instructions into controlled milliampere outputs, the card forms a vital link between a motion controller’s logic section and the electromechanical elements that carry out automated machine movements with stable analog regulation.

The amplifier’s input stage consumes less than 200 mA, minimizing the load imposed on the shared low-voltage bus. A built-in linear regulator delivers a stabilized supply of ±15 V that feeds the analog processing blocks without being affected by upstream ripple or normal supply variation. Command information is converted into a controlled loop of ±60 mA, and this symmetrical range allows bidirectional magnetization of the connected transducer. That current is intended for coils with about 2000 Ω of resistance, helping the setpoint be reached without thermal overload. To overcome mechanical stiction, the output is superimposed with a dither signal of 340 Hz / 3 mAss, a frequency-and-amplitude pair selected to remain outside the control bandwidth while reducing hysteresis.

The modulation hardware refreshes the drive signal on a 1 ms cycle, providing fast updates that support correction in servo loops. Physical integration is simplified by the board’s 5.08 mm division width, which aligns with standard Eurocard guides. All power, command, and feedback lines enter through a DIN 41612 Form D, 32-pole connector, which keeps termination organized and helps simplify cabinet integration. The assembly weighs only 0.20 kg, so it can be handled easily during installation or service in multi-axis control cabinets.
