Product Description:

The KDA 2.1-050-3-A0I-W1 state-of-the-art controller is designed to improve the efficiency of industrial machines by providing reliable control of the speed, position, and torque output of motor units. This controller is a product of Bosch Rexroth, it is an intelligent device that should only be used with motors that belong to the 1MB frameless spindle, and 2AD asynchronous series. The design of this servo controller is characterized by its high stiffness, impressive positioning features and the ability to handle a wide speed range. There is also a programming module carrying configuration parameter information and inserted into the programming slot present on this motor unit. The operation of this motor requires the skill of authorized personnel; this control process is made easier by a display unit and a keyboard present on the control panel present on the front panel of this unit.

There is a Motor NTC connection interface present on the KDA 2.1-050-3-A0I-W1. This connection receives feedback from the thermistor integrated into the motor winding and helps the motor to automatically shut down the servo motor when it is at a risk of overheating. Other connection interfaces integrated into this product include the Bus interface for control voltage, blower bus connection, output blower bus connection and the grounding connection. The control panel of this product also features two LEDs that automatically alert operators to any internal problems.

The KDA 2.1-050-3-A0I-W1 industrial controller is an IP20 unit; the relatively low amount of protection provided by the housing of this motor makes it necessary for it to be mounted inside an enclosed control cabinet that can provide protection against dust and splashes. The programming module necessary for the configuration of this product is shipped and delivered with it.
