Product Description:

The 19.H6.ACS-11B0 is a drive module from KEB within the H6 Combivert Multi-Axis Drives series. Designed for panel-mounted installation, the unit acts as an inverter stage that supplies controlled three-phase power to servo or induction motors in coordinated machine axes. In automated lines, it connects to an EtherCAT system bus and follows the CiA 402 application profile, allowing the host controller to issue position, velocity, or torque commands through standardized objects.

The module has a rated input of 400 V AC and a continuous line current of 60 A. From that supply, the converter delivers up to 30 kW of active power and 42 kVA of apparent output. Peak machine accelerations are supported by a maximum phase current of 90 A, while the internal control limits the switching frequency to 4 kHz under nominal load. Internal electronics generate 79 W of power loss, while the heat sink dissipates 382 W, and these values must be considered when establishing enclosure airflow. A dedicated brake output supplies 24 VDC at 3.3 A for motor-mounted holding brakes. The module has a width of 100 mm, allowing it to fit into standard drive stacks.

Protective functions activate when the drive approaches its operating limits. The hardware can increase the carrier frequency to 8 kHz when sufficient thermal capacity is available. An overcurrent threshold of 108 A disconnects the inverter to protect the output stage from excessive electrical stress. Temperature sensors report an overheat threshold of 80 °C, prompting the drive to reduce its output before a thermal shutdown occurs. The housing has an IP20 classification, so the module requires installation inside a closed control cabinet to prevent accidental contact with internal components. These protections operate alongside the current and temperature controls that regulate the inverter during changing motor loads.
