Product Description:

The DDC01.1-K050B-RL45-01-FW is a controller unit that significantly improves automation systems by ensuring the accurate control of AC servo motor units. This controller unit is from Bosch Rexroth Indramat and is particularly suited for the control of motors that belong to the MDD servo motor series. Unlike most industrial drive controllers, this unit is built to meet the IP65 protection class; this high degree of protection makes it possible for it to be directly mounted to the forward feed unit. Also, additional protection from a control cabinet might not be necessary for this drive controller. The cooling of this product occurs through the external air blower; for efficient cooling to happen, the unit must be mounted in a way that prevents the flow of cooling air from entering or exiting the unit.

The DDC01.1-K050B-RL45-01-FW controller generally requires no type of maintenance operation; however, the operation of the unit in highly polluted environments might make it necessary for operators to carry out regular cleaning of the dust that will accumulate at the blower mesh and heatsink integrated into the housing of the unit. The DDC01.1-K050B-RL45-01-FW controller is required to be fully configured for proper operation. The fully configured controller should feature the basic unit, software module, configuration rating plate and the single-axis positioning module.

The basic unit of the DDC01.1-K050B-RL45-01-FW is made up of a DC bus rectifier, the bleeder resistor, and a mains section for the control voltage. The integrated bleeder resistor makes it possible for the converter to handle regenerated energy during motor deceleration and convert it to heat, which is easily eliminated. The integrated software module of this unit carries configuration parameters that match the drive controller to the motor and the mechanical system of the machine the motor is used with.
