Encoder cable length restriction

If the cable length is longer than 100 m, speed may not be read correctly due to voltage drop and waveform deformation of the encoder signal. Therefore, use ... More Details >>

How can I have the motor coast to stop?

You can use the following two methods:1. Turn ON MRS at the same time when STF turns OFF.2. Set Pr.10 = 60 Hz, Pr.11 = 0 sec, and Pr.12 = 0% (when the invert... More Details >>

Brake unit selection

Since the FR-A540-0.75K has a brake transistor for resistor regenerative driving inside the inverter, you do not need to use BU. Just remove the jumper from ... More Details >>

0 Hz output of inverter

When the command frequency is 0 Hz, the inverter does not generate output and the voltage is 0 V. More Details >>

S-shape acceleration/deceleration of the FR-D700

It does not change even when General-purpose magnetic flux vector control is performed. Pr.3 is the inflection point of the S-shape. More Details >>

FR-A800-E

It is not possible because the RS-485 terminal block is not installed. Use the FR-A800 (RS-485 communication type) when performing the RS-485 communication. More Details >>

Load characteristics fault detection

Only the V/F control is related with Pr.56. The motor torque is calculated from the current value (not Pr.56) and motor constant. For the V/F control, it is ... More Details >>

Inverter built-in fuse

For the inverter with capacity of 160K or higher, the fuse is built in its DC part. More Details >>

Setting resolution

V/F control/Advanced magnetic flux vector control/Sensorless vector control: 0.3 rpm increments, Vector control with encoder: 0.1 rpm increments More Details >>

FR-F800

No, it isn't. Use the multiple rating (LD, SLD) of the FR-A800. More Details >>
