4. Cut off the power supply and wait until keypad display disappears completely.
5. Switch on the power supply again.
6. Conduct the communication with PLC.
 Setting of Communication Parameters
To communicate with PLC, communication-related parameters should be set. In the following table, only Pb.01 (ID
Number) and Pb.04 (response delay time) can be revised during operation to facilitate debugging, which becomes
effective immediately, while the rest parameters cannot be revised during operation. Then can only be set during the
stop time, and the reset parameters will not become effective until the inverter is powered off and then restarted.
"○" revisable during operation；"×" non-revisable during operation
