  • Page 99 (3) Transmission procedure 1) Set communication functions H30 through H39. 2) Make communication according to transmission frames. 3) If no response returns for one second from the inverter upon a frame from the host, retry communication. Several retries indicate certain errors. Make investigation. 4) If no communication is received from the host for 30 seconds after the first operation command is received, the inverter judges a transmission breakdown error and shuts down the inverter output, leaving the motor to coast to stop.

    12-1General In accordance with the provisions described in the European Commission Guidelines Document on Council Directive 89/336/EEC,Fuji Electric Co., Ltd. has chosen to classify the FVR-E11S range of inverters as "Complex Components". Classification as a "Complex Components" allows a product to be treated as an "apparatus", and thus permits compliance with the essential requirements of the EMC Directive to be demonstrated to both an integrator of FVR inverters and to his customer or the installer and the user.
