Frequently Asked Questions

What synchronization capabilities does Bosch Rexroth Indramat DKR04.1-W400E-BE56-01-FW provide for multi-axis servo motor applications?

The DKR04.1-W400E-BE56-01-FW utilizes its SERCOS interface and rigid DC bus to synchronize multiple servo motors, ensuring minimal latency, tight coordination, and accurate velocity-phase alignment in demanding automation networks.

Does Bosch Rexroth Indramat DKR04.1-W400E-BE56-01-FW allow rapid emergency stop functions for motors in critical tasks?

Yes, the drive executes immediate torque-off and energy dumping via its brake chopper, ensuring safe motor deceleration while maintaining integrity of both bus and automation network.

Where in system architecture does Bosch Rexroth Indramat DKR04.1-W400E-BE56-01-FW motor controller integrate relative to PLC?

Positioned as the field-level actuator, it links directly with supervisory PLC through SERCOS, executing motor commands locally with deterministic timing independent from higher control latencies.

What is the rated current Bosch Rexroth Indramat DKR04.1-W400E-BE56-01-FW delivers to connected motors?

This controller outputs a rated 400 A continuous supply, supporting large industrial servomotors with consistent torque delivery for applications requiring rapid acceleration and high inertia handling.

What drive braking advantages does Bosch Rexroth Indramat DKR04.1-W400E-BE56-01-FW external bleeder provide?

The external bleeder module dissipates braking energy externally, reducing thermal accumulation inside the drive and prolonging component life under frequent motor stop-and-hold cycles.
