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).

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.
When inverters are operated under the control of a computer, read “command from the master
inverter” in the following equations as “command from the computer.”
