Product Description:
Bosch Rexroth Indramat manufactures the VT 16005-22. The VT 16005-22 servo amplifier controls the voltage and current of industrial servo mechanisms. It accepts an internal control voltage between 0 and ±10V. This range of input voltage allows the amplifier to understand many control signals, position the attached servo motor precisely and control its velocity. Bi-directional control is possible by the ability to handle positive and negative voltages which is necessary for dynamic movement. With an optional ±100 mA design, the output current of ±60 mA ensures the amplifier can power the servo motor directly and affect the motor’s torque and speed. The VT 16005-22 can operate on two different voltage combinations, so it defines its power supply requirements. The amplifier needs a controlled ±15V power source after the internal voltage regulators are removed. In some cases, this makes the power supply design simpler.
The amplifier can tolerate a wider power supply voltage range of ±22 to ±28V after the regulators are added. Due to its flexibility, the amplifier can be used in many industrial power supply configurations and is compatible. The device’s power efficiency is shown by the power supply current, which is set to be less than 200 mA. This reduces power consumption while maintaining stable operation. To reduce heat generation and ensure long-term reliability, this low current is necessary. The physical dimensions of the VT 16005-22 are 100 x 160 mm according to the Euro card standard (DIN 41 494). Because of its standard form factor, it can be easily mounted in industrial control cabinets and uses space more efficiently. With an 8 HP width and approximately 3U (5.05 inches or 128 mm) height, the front plate is designed for easy access and connection.
The amplifier weighs only 0.33 pounds (0.15 kg), so it’s light and small, which reduces the total weight of the control system and makes it easier to handle during installation and maintenance. The VT 16005-22’s dither current with an amplitude of approximately 3 mApp at 340 Hz is one of its features. A small oscillating current is injected to counteract static friction in servo valves. The dither current prevents the valve from sticking which can cause servo response delays and errors by moving it slightly continuously. This feature reduces hysteresis and improves overall servo system accuracy and efficiency. For the relay in the amplifier to operate reliably, the nominal coil resistance of 2000 Ω and the relay coil voltage requirement of 22V to 28V is necessary. The relay’s duty cycle of 1 ms means how long it can be turned on continuously and ensures accurate control and switching.
