Product Description:

The KDA 2.1-050-3-A0D-W1 controller unit combines past experience and sophisticated automation technology to form an intelligent unit that can be used for the monitoring, control, and diagnosis of Bosch Rexroth motor series. This controller is widely used across various industries. It comes with a programming module that can be used by customers to set operation parameters and modify the operation of the unit to meet specific operation requirements. The IP20 protection provided by the enclosure of this control cabinet only protects against large foreign solids. To guarantee optimum operation, the drive should be mounted in an enclosed cabinet that is able to meet IP54 protection standards. This controller unit is able to provide reliable speed control over a speed as low as 0.0005 revolutions per minute; it can also support the maximum speed level of the 1MB and 2AD motor units respectively.

The KDA 2.1-050-3-A0D-W1 features a single amplifier axis and operates with an input current determined to be about 50 amperes. The maintenance of a low air temperature is crucial to the operation of this unit. This low temperature requirement is maintained by an ambient air blower and heatsink integrated into the control cabinet for easy heat dissipation. The rated output power of this controller generally depends on the type of application it is used with; however, this value is approximately 22 kilowatts. Three is a three-phase connection interface on this product; the voltage supplied through this interface can be between 220 to about 230 volts.

The KDA 2.1-050-3-A0D-W1 controller features both an analogue and digital connection, and it is also equipped with the Servo Bus. The KDA 2.1-050-3-A0D-W1 provides overvoltage, undervoltage, and overcurrent protection on any motors connected to it.
