PARAMETERS
4.16 Monitor display and monitor output signal
4.16.1 Speed display and speed setting (Pr. 37, Pr. 144, Pr. 505, Pr. 811)
* The maximum value of the setting range differs according to the Pr. 1 Maximum frequency and Pr. 505 Speed setting reference settings
and it can be calculated from the following formula.
Maximum setting value of Pr. 37 <
Note that the maximum setting value of Pr. 37 is 9998 if the result of the above formula exceeds 9998.
