System Architecture & Signal Flow
The EVF9328-EHV100 accepts 3-phase AC mains input through an integrated EMC filter and rectifier stage, converting to a regulated DC bus. The IGBT inverter stage synthesizes a variable-frequency, variable-voltage output to the connected motor. Control signals are processed by the onboard DSP, accepting analog (0–10 V / 4–20 mA) and digital I/O, with fieldbus commands overlaid via the communication interface. The drive supports master-slave synchronization for multi-axis coordinated motion via CANopen.
