Product Description:
KDA 2.1-100-3-L00-U1 model is among the top spindle drives from Bosch Rexroth Indramat company. This drive controller centralizes spindle power management. Its input voltage of 3 × 400–480 V AC ±10% streamlines easy integration into industrial power networks. With its input frequency of 50 Hz or 60 Hz accommodates global electrical standards to maintain consistent motor performance.
Device’s rated current of 100 A delivers substantial torque capacity that can support heavy cutting loads. Support for a single axis simplifies system architecture which reduces cabinet footprint. This mechanism of Internal air cooling via forced ventilation maintains optimal device temperature thus prevents thermal shutdowns. Control voltage of 24 V DC drives internal logic circuits to isolate low-voltage control from high-power stages. The ingress protection of IP20 guards against solid objects bigger than 12 mm, and hence it prevents inadvertent contact with live parts. Approximate weight of 18 kg offers a balance between rugged construction and manageable handling for an easy installation. Overall dimensions of 358 × 432 × 270 mm fit standard rack spaces with maximized panel density.
The KDA 2.1-100-3-L00-U1 DC bus voltage operates at 300 V DC, stabilizing energy flow and enhances drive efficiency. The SERCOS interface speed command value provides deterministic communication which synchronizes spindle speed with tight timing requirements. Allowing blower power supplied at 115 VAC for the heatsink blower ensures consistent cooling performance, preventing overheating under intensive operational demands. Auxiliary encoder input is omitted that reduces interface complexity when closed-loop feedback is managed externally. Further, with an auxiliary interface absence, it simplifies wiring requirements and minimizes potential points of failure in control connections.
