Frequently Asked Questions
What are the primary input line voltage requirements for the Bosch Rexroth DKR03.1-W200B-BA05-01-FW drive?
This drive requires a balanced three-phase AC input between 400 V and 480 V, operating at 50–60 Hz, ensuring proper energy delivery to internal electronic assemblies.
Does the Bosch Rexroth DKR03.1-W200B-BA05-01-FW drive support regenerative energy return during deceleration cycles?
Yes, it supplies up to 30 kW continuous and 55 kW peak regenerative power back to the mains, significantly reducing waste and improving system-level electrical utilization.
What method ensures temperature regulation in the Bosch Rexroth DKR03.1-W200B-BA05-01-FW drive during extended duty cycles?
An air-cooled heatsink structure extracts generated heat, maintaining thermal equilibrium across insulated-gate modules to prevent instability during continuous industrial drive operations.
How does the Bosch Rexroth DKR03.1-W200B-BA05-01-FW drive achieve compliance with EN60529/IEC529 IP20 protection?
The enclosure follows IP20 design by limiting ingress of solid objects larger than 12.5 mm, ensuring safe use in controlled industrial cabinet-mounted environments.
What control voltage is required for internal electronics of the Bosch Rexroth DKR03.1-W200B-BA05-01-FW drive?
A dedicated 230 V supply provides 200 VA of control power, energizing the internal logic and peripheral circuits required for drive sequencing and monitoring.
