9. Serial Link Timeout. This is the maximum permissible period between two incoming data telegrams. This feature is used to turn off the inverter in the event of a communications failure. WWW_PLCJS※COM－PLC－技×术_网(可编程控※制器技术门户)
WW.W_PLC※JS_C,OM－PL,C－技.术_网
Timing starts after a valid data telegram has been received. If a further data telegram is not received within the specified time period, the inverter will trip and display fault code F008. Setting the value to zero switches off the control. The time between the status polls to the drive can be calculated using Table 1–1.WWW_PLC※JS_COM－PLC－技.术_网(可编程控※制器技术门户)
