Read H6F
H0000 to HFFFF: Output frequency in 0.01Hz increments
Speed increments 1/0.001 (when Pr. 37 = 0.01 to 9998)
When "0.01 to 9998" is set in Pr. 37 and "01" in instruction code
HFF, the increments change to 0.001 and the data format is E2.
When "100" is set in Pr. 52, the monitor value is different
depending on whether the inverter is at a stop or running.
