Product Description:

The RS2A03A0KA4W00 is a well-constructed Sanmotion R servo amplifier that uses natural convection for cooling. With its robust chassis design and powerful set of connection ports, the RS2A03A0KA4W00 can be used for a wide variety of applications and installation environments. As a servo amplifier, the RS2A03A0KA4W00 can accommodate a rotary servomotor using a serial encoder. As opposed to pulse encoders, serial encoders can provide higher resolution and precise position tracking through serial communication. Pulse encoders utilize pulse signals to encode motor position, speed, or torque relative to a reference point or starting value. Serial encoders, on the other hand, can transmit data packets containing absolute position/speed information of the servomotor at any point in time.

As part of the advanced Sanmotion R series, the RS2A03A0KA4W00 requires a nominal voltage input of 200 V. It has a capacity of 30 A and operates with a built-in regenerative resistance and DB resistance. Unlike other servo models available on the market today, the RS2A03A0KA4W00 employs a special safe torque off feature that can halt the motor safely without withholding power from the servo amplifier. Overall, the RS2A03A0KA4W00 has two versatile inputs and two versatile outputs. The safe torque off feature for this unit employs a delay circuit for added noise immunity.

Servo amplifiers such as the RS2A03A0KA4W00 are intended to be a part of a larger system. Aside from the servomotor, the RS2A03A0KA4W00 may be connected to other devices for protection or communication. Specifically, this unit may be connected to a circuit breaker, noise filter, EMG switch, or an external regenerative resistor. In terms of other communication devices, the RS2A03A0KA4W00 can support another servo amplifier, an industrial PC, a host device, or a PLC unit.
