User Manual of EM760 High-Performance Inverter Table 6-36 shows the data sending segment (t send ), sending end segment (t wait1 ), 75176-to- sending wait segment (t wait2 ), data return segment (t return ), and 75176-to-receiving wait segment (t wait3 ). Fig. 10-5 Timing Parse Diagram of Complete Data Frame 10.4.4 Communication timeout The communication time interval △ t is defined as the period from the previous reception of valid data frames by the slave station (inverter) to next reception ofvalid data frames. If △ tis greater than the set time (depending on the function code F10.03; this function is invalid if set to 0), it will be regarded communication timeout. Fig.
