Dear members,
I'm now working with VFD ( Inverter) from mitsubishi.
The spec for the inverter is FR-A520-5.5K ( for 5.5kW motor).
The application for this motor is hoisting process.
For this application, the inverter using with brake resistor spec 300w and 100ohm. I'm face the problem with overcurrent fault each time motor want to stop.
Error will come out when there have any increasing or decreasing speed of motor.
From manual, I need to set parameter 30 to 1 value and parameter 70 to 10% value when using external brake resistor. The system working as normal without load but over current fault when there have load..
What i need to do now? Anyone from this forum can help me?
