‹Load and line speed

Use the display coefficient A.

Displayed value = output frequency x (0.01 to 200.00) Although the setting range is ±999.00, the effective value range of display data is 0.01 to 200.00. Therefore, values smaller or larger than this range are limited to a minimum value of 0.01 or a maximum value of 200.00.

‹Target value and feedback amount of PID controller Set the maximum value of display data in E40, "Display coefficient A," and the minimum value in E41, "Display coefficient B."
