perform the following functions for up to 63 Inverters.
(1) Cyclically scans the Inverters and sends/receives the following data to/from each Inverter.
•
Send to Inverter: Frequency reference write and Operation command write (Run, Stop, etc.)
•
Receive from Inverter: Operating frequency monitor and Output terminal status monitor
