Product Description:
Bosch Rexroth Indramat manufactures the VT 1600 S31/1 servo amplifier. The VT 1600 S31/1 servo amplifier is designed to control motors in industrial automation systems. The ±60 mA to ±100 mA output current range is important for servo motors with different torque and speed requirements. This range determines the motor’s acceleration and torque production by the amplifier’s ability to supply the required current to the motor windings. A motor with a higher current capacity can handle larger loads and quicker dynamic responses. By adjusting the amplifier to different motor sizes and operating conditions, this output current selection gives flexibility and improves system performance. The VT 1600 S31/1 has 3 mApp dither current at 340 Hz. Dither is the process of adding a small high-frequency oscillation to the control signal in servo systems. Static friction or stiction inside the motor and mechanical connections is reduced by this oscillation, which in this case is 340 Hz. When the force required to start motion is much higher than the force required to keep it going, this is called stunting.
The amplifier prevents the motor from settling into a static position by supplying a dither current, which keeps it moving in small increments. This improves the servo system’s overall accuracy and produces smoother and more accurate movements, especially at low speeds. To prevent resonance with the mechanical system and to ensure steady and consistent operation the dither current frequency is carefully selected. Another important feature is the amplifier’s power supply flexibility. It can run with controlled ±15V or uncontrolled ±22 to ±28V supply. Because of its flexibility, it can be used in many industrial applications where power supply fluctuations are common.
The amplifier’s efficiency and low power consumption are shown by its power supply current of less than 200 mA. The internal control voltage range of 0 to ±10V makes it compatible with different controllers and allows typical analog control signals. The relay data describes the electrical properties of the relay, which is important for integration with external control circuits and safety measures. These properties are nominal coil resistance of 2000 Ω, duty cycle of 1 ms and coil voltage of 22V to 28V. For compact applications, the VT 1600 S31/1’s light weight (0.33 lbs or 0.15 kg) and physical size (Euro card size 100 x 160 mm) are ideal. The front plate is divided into width divisions (8 HP) and height units (3U) for uniform installation in rack systems, making installation and maintenance easier. The amplifier is reliable in many industrial applications with its storage temperature range of -4 to 158 °F (-20 to 70 °C), which protects it from heat stress and ensures operation.
