Product Description:

The HCS04.2E-W0390-N-06-NNNN is a drive controller from Bosch Rexroth Indramat in the HCS IndraDrive Controllers series. In multi-axis automation cells, it regulates power modules and motors while coordinating torque and speed loops from higher-level PLC setpoints. By integrating an infeeding power supply unit, the device supplies energy to connected axes and returns regenerative power to the DC bus, supporting efficient motion sequences in packaging, printing, and material-handling lines.

The controller uses internal air cooling through an integrated blower, so an onboard fan pulls cabinet air through the heat sink and removes the need for external ducts. A control loop updates at 4 kHz, and this nominal clock frequency sets the PWM timing that drives the IGBTs and influences current ripple. For motor excitation, it can deliver an output frequency of up to 300 Hz, allowing high-speed spindle or servo operation. Protection against line transients falls under Category III of the overvoltage scale, which suits fixed industrial wiring. During short overload events, Power 1 can rise to 50%/65% above nominal for 60 s or 2 s respectively, while a second channel permits 20%/35% overrating. The PELV insulation concept keeps control circuits at a safe potential relative to protective earth, and the unit is intended for vertical mounting to maintain the internal airflow path. Communication hardware is not specified, so fieldbus expansion can be selected separately.

Ingress protection varies by location on the housing: the bottom is open at IP00, the front and sides meet IP31, and the top edge attains IP20. These enclosure levels help determine cabinet placement so falling debris or accidental contact does not interfere with operation. The unit tolerates relative humidity up to 95% without condensation when properly derated, and its Class 1 protection class uses a grounded conductive enclosure.
