The operation frequency (frequency command value) of the inverters are calculated using the fol-
lowing equations, with the received data in the following equation used as the data received from
the master inverter when inverters are operated under the control of a master inverter (inter-drive
communication), or with the received data in the following equation used as the data received from
the computer when inverters are operated under the control of a computer (computer-linked opera-
tion).

 If the “Frequency point selection” function is enabled (f810≠0)
When inverters are operated under the control of a mater inverter, the operation frequency (fre-
quency command value) of the slave inverters are calculated using the following equations.
Just as the master inverter is calculated to the data, personal computer has to send the same data.
