Product Description:

The HCS02.1E-W0070-A-03-NNNV is a drive controller from Bosch Rexroth Indramat that belongs to the HCS IndraDrive Controllers series. Within an automation cell, it works as the power-processing interface between a three-phase mains supply and synchronous or induction motors, regulating torque, speed, and position on coordinated motion axes. It is intended for cabinet-mounted drive systems where a single controller must support precise motor control across changing load conditions, including applications that require repeatable axis movement, stable speed regulation, and coordinated positioning with neighboring axes.

This controller accepts a supply of 3 x AC 200…500 V ±10%, allowing the same hardware to be connected to 200 V class or 400 V class networks without tap changes. During dynamic load steps, the unit can deliver up to 70 A of peak current, allowing short acceleration bursts during rapid speed changes before current limiting is invoked. The continuous output range is 1.5 to 11 kW, so one model can support several motor frame sizes used in different machine sections. Internal thermal management uses internal air cooling through an integrated blower that draws cabinet air across the heat sink, avoiding external ductwork while keeping semiconductor junction temperatures within limits during sustained operation. An enclosure rating of IP20 indicates finger-safe protection against solid objects larger than 12 mm but no resistance to water ingress, so the unit must be mounted inside a control cabinet with appropriate environmental protection.

The DC link provides auxiliary logic power at DC 24 V, and the same rail feeds an integrated brake transistor that dissipates regenerated energy during deceleration. Power can be sourced from or returned to a common supply because the controller supports infeeding and fed operation, which allows shared-bus topologies with energy recycling between connected axes. The unit is design version 1. The internal circuitry and I/O layout follow the HCS02 line concept, which keeps connector locations consistent across related multi-axis assemblies and helps maintain orderly cabinet wiring.
