Product Description:

The Bosch Rexroth Indramat KDA 2.1-050-3-DQI-U1 is a digital control type that is a component of the KDA Spindle Drives family. It can be mounted on a panel. It can always produce 50 A (Amperes) of current and has an integrated fan that cools it down. It weights 16 kg (kilograms) and can operate in temperatures between 0 and 45 degrees Celsius. The heatsink blower needs 115 VAC of AC (Alternate Current) power to work. There is an extra encoder input in the system that is designed for 1V (One volts) sinusoidal encoders. An incremental encoder output is available via the auxiliary interface. The heatsink blower makes the air flow faster, which cools the system.

The gadget is rated to work with a DC bus voltage of 300 volts. 1 is the design version of the device. The model of the product in issue is KDA. The rated current for use is 50 A (Amperes). This unit is part of series 2. The speed command value comes in as a digital 16 bit signal (parallel). To dissipate heat from the motor after continuous operation, it comes equipped with a blower. For the blower to operate optimally, it gets a continuous power supply of 115 VAC (Volts of Alternate Current).

The stiffness of this spindle drive is high, which makes it more suitable for varying industrial settings. The power type is continuous. The primary spindle drive values in the selection data are only valid when the drive works in temperatures between +5° C and +45° C. This temperature measurement in Fahrenheit scale is  41° F to 113° F. The highest temperature that is safe for the environment is +55° C.
