Inverter operation against power supply voltage drop

Depending on the load current, undervoltage protection (UVT) or instantaneous power failure protection (IPF) is triggered to shut off the inverter output, an... More Details >>

Using dedicated motor

Since the inverter power supply uses the single-phase input, you cannot use a 0.75K inverter with a 0.6 kW motor to draw the maximum ability of the motor. To... More Details >>

Installing magnetic contactor on input side of inverter

Basically, there is no difference between the A200 and A500. For safer use, from the A500, it is recommended to completely shut off the power supply by turni... More Details >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... More Details >>

Compressor

You can use an inverter for fan and pump with the compressor, but it is not recommended for an application that the motor load rapidly increases. More Details >>

Long motor wiring

When you use a long wire between the inverter and motor, pay attention to the following: 1. Since the voltage supplied to the motor terminal is reduced due t... More Details >>

Durability in multi-speed setting

1. You can set the minimum time by setting the acceleration/deceleration time and acceleration/deceleration reference frequency. 2. No problem with the termi... More Details >>

Overcurrent

Frequent occurrences of OL means that the inverter is overloaded. Since the inverter can go faulty if it is constantly overloaded, you need to take a counter... More Details >>

CC-Link monitor and parameter setting

1. Since you can monitor the output frequency independently, you do not need to switch monitoring by the monitor commands. Assign the remote register RWr0 to... More Details >>

Parameter unit

The FR-PU02-1 cannot be used with the FR-B3 series inverters. 　Use the FR-DU04 or FR-PU04. More Details >>
