Static torque

When a vector inverter is used for position control, the servo lock works when it is stopped. When the start signal (STF or STR) is turned ON, the servo lock... More Details >>

What is the replacement of the FR-BOL?

We do not offer a replacement product for the FR-BOL (noise reduction reactor). Since the FR-A100E is a low-noise type inverter, the motor noise is suppresse... More Details >>

CC-Link

Although you specify the FR-V200 and others as the inverter models, CC-Link is currently supported by the FR-A500 and FR-E500. The FR-V200E does not support ... More Details >>

Energy saving and power supply capacity of inverter

Energy saving is achieved by switching from the commercial power supply to the inverter to operate the motor. When the inverter reduces motor speed, it also... More Details >>

Auxiliary input power supply

If you connect two frequency setting potentiometers to the terminals 5 and 10, the permissible current of 10 mA is exceeded, and you need to install 2 KΩ res... More Details >>

Simple torque control using stall prevention function

Basically, torque control cannot be performed. Instead, control speed to adjust the winding torque. It is possible to use the current limit function to preve... More Details >>

Speed does not exceed 46 Hz

Since the inverter displayed "0.00" instead of an error when the inverter speed dropped to 0 Hz and stopped by holding the winding machine by hand, it is con... More Details >>
