VHZ
Is an acronym for Volts per Hertz control, one of the control modes in the drive. This mode is
intended for multiple motors connected in parallel. Therefore, it disables spinning load and fast
bypass. This is essentially open-loop vector control with de-tuned (smaller bandwidth obtained
by reducing the gain) current regulators.
