Product Description:
Bosch Rexroth Indramat manufactures the VT 5015 S31. A key part of industrial automation, the VT 1532-10 servo amplifier takes the input signal and converts it into a proportional current to drive a torque motor and then a servo valve. Basic electrical engineering and control system knowledge is used here. The process is signal transduction; it takes an input voltage that says where you want to be or how fast you want to move and converts it into an exact output current. The direct correlation between this current and the motor torque allows for accurate positioning and motion control. The amplifier can be configured to match the characteristics of the connected torque motor with the output current options of ±60 mA or ±100 mA. The power supply specs of the VT 1532-10 show how well it can adapt to different electrical situations. The amplifier operates within the regulated power supply range of ±22V to ±28V when fitted with voltage regulators.
For accurate motion control, a steady and constant output current is required, this is achieved by the regulation. The voltage regulators act as active parts and reduce the impact of input power supply changes by keeping the output voltage within the specified range. But when the voltage regulators are removed, the amplifier can also operate with an unregulated power supply of ±15V. Although not as precise, it can be used in applications with less reliable power sources. The amplifier’s efficiency and power consumption are shown by the power supply current, which is less than 200 mA. The input signal levels the amplifier can handle are shown by the internal control voltage range of 0 to ±10V. This range makes it easy to integrate with different controllers and sensors as it complies with industry standards for analog control signals. The dither current is a small high-frequency signal overlaid on the control signal; its amplitude is usually 3 mApp at 340 Hz.
To have accurate and smooth valve operation, dither is important to reduce static friction in the servo valve. The dither improves responsiveness and precision by preventing the valve from sticking by generating a small oscillation. The relay requirements specify the features of an integrated relay for auxiliary purposes, a nominal coil resistance of 2000 Ω, a duty cycle of 1 ms and a coil voltage of 22V to 28V. To fit the VT 1532-10 into industrial control cabinets, its physical dimensions are essential: a Euro card of 100 x 160 mm according to DIN 41 494, a front plate height of 3U (around 128 mm) and a weight of 0.15 kg. The small design allows for control components to be packed tightly, so less space is required. Easy installation and maintenance are possible due to the Euro card format’s mechanical compatibility with common rack systems.
