Pre-excitation, zero-speed control, and servo lock

Pre-excitation is the process to control current while a motor is stopped so that motor torque can be generated immediately. There are two methods for this p... More Details >>

Terminal CS

FR-E700, D700, and F700PJ do not have the terminal CS and you can only control automatic restart by setting Pr.57 (Restart coasting time). More Details >>

Parameter setting

Check if Pr.13 (Starting frequency) is set to higher than 10 Hz.Also check if a signal is input through the terminal MRS. More Details >>

Frequency setting

You cannot calibrate the frequency around the middle of the current input range.The inverter determines the top and bottom points in the bias/gain adjustment... More Details >>
