FR-A500 main circuit wire types

Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. More Details >>

Two-rank up maximum short-time torque

It is not possible to generate torque larger than the maximum possible torque of the motor by increasing the inverter's capacity.Even when the inverter is up... More Details >>

Changing main speed at analog signal ...

To change the running frequency while the frequency command is input to the terminal 2, adjust the parameters in the following steps:1. Change Pr.77 to "2".2... More Details >>

Driving two motors with different cap...

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 >>

Built-in regenerative resistor

For both the 200 V and 400 V classes have the built-in regenerative resistor for 0.4 K to 7.5 K.The permissible power is as follows:Capacity: Short-time perm... More Details >>

Speed precision of Advanced magnetic ...

The speed precision for each model is as follows:FR-K440 with PG: 1% or less of the maximum speed (3500 rpm)FR-A540 without PG (Advanced flux vector): 1% or ... More Details >>

Speed control failure due to 20 mA fr...

It seems that there is a read error for 20 mA DC inside the inverter.Setting Pr.905 to 50 Hz while 20 mA DC is actually flowing between the terminals 4 and 5... More Details >>

Terminal FM

Since the terminal FM is designed with 8 V peak pulse voltage output, it cannot output 10 V.Since the terminal AM is an analog output of 0 V to 10 V, use thi... More Details >>
