Things to know about your VFD
• When power is first applied to the VFD it requires
four seconds for the startup sequence before
becoming functional.
• On initial power up or when the conveyor stop has
been activated the VFD is in fault status until the
fault has been cleared by pressing the Red Soft
Stop key.
• Phasing of the input power does not effect the
phasing of the VFD’s output power.
