Product Description:

Built for demanding environments, the 17-2220D200-B055 is a smooth and precise servo controller from Pacific Scientific. It is designed for reliable and flexible motor control. It operates with an input voltage of 230 VAC and can be configured to work with either single-phase or three-phase power input. This flexibility makes it suitable for different industrial setups. The device uses a nominal DC bus voltage of 310 V, with a brief inrush current limit of 80 A for 4 milliseconds to protect the system during power-up.

This brushless servo controller supports Hall-effect or Tachsyn commutation inputs, ensuring accurate motor positioning and speed sensing. It offers ~12 VDC control supply outputs with a maximum output of 100 mA, which can be used for powering external control electronics. The velocity command input is either a ~10 V analogue signal or a 4-20 mA current loop, thus ensuring compatibility with various control systems. This servo controller also includes current limit adjustments from 10% to 100%, thus allowing customization based on the motor's load requirements.

Another key feature of the 17-2220D200-B055 is its dynamic braking capability through a shunt resistor via the DC bus voltage, which helps safely dissipate energy during rapid deceleration or emergency stops. The controller includes several protection circuits, such as input fuses, a motor over-temperature input (PTC-based), which ensure the system operates safely under various conditions. With 3-phase outputs, adjustable command gain, and torque limit input, this unit provides precise and robust control over motor performance. The 22 AWG or larger shielded signal wiring of the servo controller ensures noise resistance and signal integrity in industrial environments, making this controller a dependable choice for motion control tasks.
