fmod Speed command selection
f200 Frequency priority selection
f207 Frequency setting mode selection 2
f208 Speed command priority switching frequency 0.1 - fh Hz
f234 RP/high speed pulse input point 1 setting
f235 RP/high speed pulse input point 1 frequency
f236 RP/high speed pulse input point 2 setting
f237 RP/high speed pulse input point 2 frequency
f375 Number of PG input pulses
f376 Selection of number of PG input phases
f377 PG disconnection detection
* Calculation of the reference frequency
The input pulse frequency is calculated to the percent base data. The calculated percent
data is converted to the frequency in accordance with 2 point setting (from f234 to
f237). Refer to the below figure. By inputting two-phase pulse with 90 degrees phase dif-
ference, it is possible to input forward and reverse rotation commands.

command
*1: The CPU software less than V104 can not detect the direction command of rotation with
two-phase input. About the CPU version, please refer to the inverter instruction manual.
