4.7 Frequency and Speed Conversion Specifications
For frequency setting and monitoring from FR-A7ND, frequency is set in 0.01Hz increments and displayed
on the monitor regardless of the Pr. 37 Speed display setting.
Speed setting and monitor values from FR-A7ND are calculated by the following formula.
* Calculated on the assumption that the number of motor poles is 4.
Speed setting, monitor (1r/min increments) = frequency × 120 / number of motor poles (4*)
