The HMD01 double-axis inverters are supplied with DC voltage and generate two independently controlled AC output voltages with variable amplitude and frequency for the operation of two motors. They have a mounting slot for a double axis control unit, which has various interfaces for connection to the automation environment, for encoder systems, safety technology and other digital and analog signals, etc. For multi-axis applications, the inverters are supplied with power from the DC bus of supply units HMV01 or HMU05. Supply from the DC bus of an HCS converter is also possible for smaller axis packages and with the corresponding power reserve of the HCS.
