Output frequency/
speed
Read H6F
H0000 to HFFFF:
Output frequency in 0.01 Hz 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. (Refer to section 6.11.2.)
