Analog signal resolution

The internal processing speed is not published. The analog input specifications are as follows: FR-A500???1/4000FR-E500???1/1000MR-H???1/4000 More Details >>

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>

Clutch connection of load

Since a large load is applied to the motor when the electromagnetic clutch turns on, overcurrent may occur if the load is heavy. To ensure that the rated cur... More Details >>

Driving two motors with different capacities

It is OK to drive motors by switching the electromagnetic contactor on the inverter's output side.It is also OK if the motor capacity is small. However, if t... More Details >>

Installation clearance of inverters

Keep 1 cm or more of clearance for 3.7 K or smaller, and 5 cm or more for 5.5 K or larger.If the clearance is too small, the cooling effect is lowered. Secur... More Details >>

Inverter installation interchange attachment

Use the FR-A5AT02 as the intercompatibility attachment when upgrading from the FR-A220-3.7K to FR-A540-3.7K. More Details >>

FR-A800

No. Check the parameter setting of the A500(L), and then adjust the parameter setting of the A800 to those of the A500(L). For the details, refer to the repl... More Details >>

Inverter operation at instantaneous power failure

When performing the automatic restart after instantaneous power failure, input the operation signal (STF or STR) and selection of automatic restart after ins... 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 >>
