DKR03.1-W200N-BE31-01-FW

Why might the DKR03.1-W200N-BE31-01-FW be preferred in CNC systems?

Its SERCOS interface ensures precise synchronization of multi-axis drives. This improves machining accuracy and reduces cycle times.

How does the absence of a bleeder circuit affect installation?

Without a brake chopper, external energy management must be considered in regenerative load conditions. This simplifies the unit design but shifts energy dissipation requirements to the system level.

What cooling considerations exist with a built-in blower design?

The blower enables compact installation without external cooling circuits. However, regular airflow maintenance is necessary to avoid overheating from dust accumulation.

Can resolver and digital servo feedback be used interchangeably?

Both are supported, but resolver feedback is more robust in harsh environments. Digital encoders, meanwhile, allow for higher resolution positioning.

What risks arise if the controller is undersized for motor current demand?

If motor draw exceeds 200 A, protection trips or thermal overload may occur. This leads to unplanned downtime and possible hardware damage.
