Product Description:

The KDA 2.1-050-3-A0D-U1 controller unit is a compact motor control device that features a metallic IP20 housing and is able to provide intelligent control an guarantees efficiency level as high as 90 percent when it used with Bosch Rexroth motor designs belonging to the 2AD asynchronous and 1 AM frameless spindle motor. The unique design of this controller allows it to function at a top level for long periods without requiring major maintenance and repair operations. Apart from motion control, this product also provides reliable protection. It features a thermistor interface and monitors the temperature in connected motors to prevent overheating. A factory-installed control panel is also made available on this controller to provide operators with a way to easily keep track of any error code and also send in command instructions in real time.

The KDA 2.1-050-3-A0D-U1 is delivered together with a programming module. This module features an operating software that works with drive-specific parameters already determined by INDRAMAT before the controller is shipped; however, there is also room for customers to adjust the operation of the motor to specific industrial requirements by setting application-specific requirements on the module. The use of this programming module is particularly useful when there is a need to transfer configuration instructions from one drive controller to the next. The parameters on the module can be easily duplicated for other similar machines or for saving.

The KDA 2.1-050-3-A0D-U1 controller requires ambient temperature that is within the range of 0 to 45 degrees. If the controller is to be kept for future use, surrounding temperature can be as low as -30 degrees and as high as 80 degrees without any effect on the performance standard of the unit.
