The R911268385 (DKR02.1-W300Z-BE23-01-FW) is a Bosch Rexroth drive controller designed for use in various industrial automation environments. It features duct cooling via a built-in blower, facilitating the dissipation of up to 1200W of heat. The unit is rated for operation up to 45°C ambient temperature with no derating, and maintains performance at installation heights up to 1000 meters above sea level. The controller requires a minimum clearance of 160mm at both the air intake and outlet, and is intended for use only with approved accessories and motors. It communicates using the SERCOS interface and supports digital servo and resolver feedback. Electrical specifications include an operating voltage of 3x400–480V and a rated current of 300A.

Frequently Asked Questions

How does the undefined bleeder specification affect system design?

It means external braking resistors may be needed depending on application load cycles. Engineers must size braking hardware correctly to avoid regenerative overvoltage faults.

What maintenance considerations arise from air-blower cooling?

Filters and air passages require periodic cleaning to avoid dust buildup, which can impair cooling efficiency. Neglecting this can shorten component lifespan due to overheating.

How does the 02 line series impact real-world use?

It reflects a later-generation design with refinements in stability and compatibility. Users upgrading from earlier series may notice improved reliability and interface consistency.

In what applications is a current of ~300A particularly useful?

It is ideal for large servo-driven presses, material handling gantries, or robotic arms with high inertia loads. The high current ensures strong torque output and reduced stall risk.

What considerations should be made for cabinet space with this controller?

Since it uses forced-air cooling, spacing for ventilation ducts is critical. Overcrowding the cabinet can restrict airflow and cause derating or shutdowns.
