Cc-Link Ie Field Network Function Setting (Fra800-Gf) - Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual

• The communication check time by query communication includes a no-data time (3.5 bytes).
This no-data time differs according to the communication speed, so take this no-data time into consideration when setting
the communication check time.
Example: RS-485 terminal communication, Pr. 539 = "0.1 to 999.8 s"

NOTE
• For the RS-485 terminal communication, the operation at a communication error occurrence depends on the Pr.502 Stop
mode selection at communication error setting. (Refer to
5.15.7 CC-Link IE Field Network function setting (FRA800-
GF)
Use the following parameters to perform required settings for CC-Link IE Field Network communication between the inverter
and other stations.
• For the details of the CC-Link IE Field Network, refer to
• For the inverter operation at communication error, refer to
• Set the parameters other than Pr.434, Pr.435, and Pr.541 in the same way as when a communication option is used.
