User Manual of A90 Series Inverter The A90 series inverter supports the master-slave communication function. That is, one inverter works as the host and others as slaves. The slaves work according to the command sent by the host, so that these inverters can work synchronously. The inverter used as the host is set as follows: F10.05=1: enable the master-slave communication function; as the host in a network); F10.06=1 or 2: select the current inverter as the host (only one inverter can be set F10.07: select the variable to be synchronized, such as the output current (set F10.07=5). The inverter is used as the slave is set as follows: F10.05=1:
enable the master-slave communication function; F10.06=0: select the current inverter as the slave; Select one setting as the communication setting. If F09.00=6 is set and the process PID is set separately (F00.05=10, F00.06=1), the slave inverter will be set to the host output current for PID adjustment. You can set the receiving proportional coefficient (F10.08) to determine how the slave inverter receives data. If F10.08=0.80 is set, the final application data is “Recv (received data) * 0.80 (F10.08)”. For the application “PLC controller/HMI + inverter”, you can set F10.56=11 after debugging.
Then all write data of PLC communication will not be stored, which can avoid damage to the memory. If you need parameter settings and power-down storage, set F10.56=0 first. 7.12 User-selected Parameter Group of F11 Group The keyboard of the A90 series inverter supports the user-selected function.
