The drive controller module R911292674 (DKR03.1-W200N-BE38-01-FW) is engineered for industrial motor control applications requiring precise regulation. It features a rated input power of 3xAC 400–480 V ±10% at 50–60 Hz, a control power supply of AC 230 V ±10%, 50–60 Hz, and a nominal current range of 78–92 A to deliver output power between 30–35 kW. The module employs digital servo and resolver feedback, is equipped with a SERCOS command interface, and operates using air cooling via a built-in blower. Its configuration includes a rigid DC bus without a bleeder or brake chopper, and an automatic shutdown function is integrated for emergency or power loss events. Operation is supported within an ambient temperature of +5 to +45°C, beyond which power derating occurs.

Frequently Asked Questions

What does “no bleeder / without brake chopper” mean for DKR03.1-W200N-BE38-01-FW?

It means the drive cannot dissipate regenerative energy internally, so any excess must be handled externally or via the mains. That requires the system design to include regenerative paths or braking resistors elsewhere.

How does the rigid DC bus topology influence control stability?

A rigid DC bus helps maintain stable DC link voltage during rapid load changes, reducing voltage dips under transient load. However, any regenerative spikes must be externally managed to prevent overvoltage faults.

Why is the 200 A rating significant beyond just power?

It defines the continuous current the controller can supply, constraining the motor size and duty cycle that can be reliably driven. It also dictates cable sizing and thermal margins for the power stage.

What are the installation constraints of the built-in blower cooling?

Adequate airflow clearance and dust control are essential to maintain cooling effectiveness. Poor ventilation or clogged intake/outlet paths can force the drive to derate or overheat.

How does SERCOS communication benefit this drive?

SERCOS provides deterministic, cyclic command/feedback exchange with low latency and high precision. It enables tight coordination across multiple axes in motion systems.
