The calculation is performed by two modes. One method calculates the current winding diameter automatically by moving the dancer roll from lower limit positi... More Details >>

Fault code

Regenerative overvoltage protection (E.OVT).This error occurs when the regenerative power returns from the motor to the inverter (for example, during deceler... More Details >>

Speed adjustment of multiple inverters using variable resistor

You can connect up to three inverters in parallel to an external variable resistor. Refer to the figure below for a connection example. By setting parameters... More Details >>

Current input switching operation

With your setting, since Pr.60 assigns the OH function to the terminal PL, and terminals RL and SD are open, an external protection error occurs. (It does no... More Details >>
