How can I calculate the processing torque from the measured power?

You can calculate the torque from the power. 　From the general equation: Pout = ωn × TT = (Pout × τ)/ωnPout: Measured valueωn: Actual motor shaft angular fre... More Details >>

Replacement of FR-Z100 series

From Z100 to A520: Use the FR-AAT01 to replace the Z100 with the A520. From Z100 to E520: No attachment is available since E520 is a new series. From Z100 to... 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 >>

Encoder feedback speed accuracy

The speed variation rate is as follows: 　- Encoder feedback control: ±0.2% - Vector control: ±0.02% (mentioned in FR-A5AP Instruction Manual) More Details >>

Unwinding using vector inverter

1. Torque control automatically adjust the speed so that the instructed torque value is maintained. This means that the speed is not controlled. (However, yo... 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 >>

"OV3" occurs during an inverter stop.

An error may have occurred due to the rise of the main circuit voltage of the inverter caused by a power surge. Check for the power supply voltage. If the ca... More Details >>
