The Indramat MPN R911286158 (DKR04.1-W300N-BE76-01-FW) is a DKR04 series drive controller engineered for the monitoring and control of compatible motors, suitable for use in industrial applications such as printing machines and NC machine tools. This controller operates with a mains supply of 400 to 480 V AC, provides a nominal current of approximately 300 A, and includes features such as an integrated mains contactor, shutdown device, and an internal blower for air cooling. Digital servo and resolver feedback are supported, and communication is facilitated via a SERCOS interface. The device allows for integration of external brake resistors and is equipped with hardware slots for customer-specific plug-in cards, command interface cards, plug-in modules, and a software module. The unit is designed without a bleeder or brake chopper and weighs 150 kg.

Frequently Asked Questions

How does the SERCOS interface benefit the DKR04.1-W300N-BE76-01-FW in automation systems?

It allows deterministic, high-speed communication between drives and controllers. This ensures precise synchronization across multi-axis motion systems.

What maintenance considerations arise from relying solely on blower-based cooling?

Fans and air passages need periodic cleaning to prevent overheating. Bearing wear in blowers can also lead to reduced cooling efficiency over time.

In which scenarios would the DKR04.1-W300N-BE76-01-FW require external braking resistors?

High-inertia loads that frequently decelerate can generate excess energy. Without a chopper, this energy must be dissipated externally to prevent overvoltage trips.

What does a nominal current rating of 300 A imply for system design?

It indicates the drive can continuously supply this current to supported motors. Proper cabling, fusing, and thermal considerations must be factored into the installation.

Why does the DKR04.1-W300N-BE76-01-FW use a rigid DC bus without a brake chopper?

It means excess regenerative energy is not dissipated internally. External energy absorption or braking systems may be needed in dynamic applications.
