 Retry count setting (Pr.121, Pr.335)
• Set the permissible number of retries at data receive error occurrence. (Refer to
• When the data receive errors occur consecutively and the number of retries exceeds the permissible number setting, a
communication fault (PU connector communication: E.PUE, RS-485 terminal communication: E.SER) occurs and the
inverter output is shut off.
• When a data transmission error occurs while "9999" is set, the inverter does not shut off its output but outputs the Alarm
(LF) signal. To use the LF signal, set "98" (positive logic) or "198" (negative logic) in any parameter from Pr.190 to Pr.195
(Output terminal function selection) to assign the function to an output terminal.
The converter unit received an unusable character (other
than 0 to 9, A to F, and control codes).
