Definition
Permissible number of retries at error occurrence
(If the number of retries exceeds the preset value,
the inverter will come to an alarm stop. (Factory-
set to 1))
If a communication error occurs, the inverter will
not come to an alarm stop. At this time, the
inverter can be coasted to a stop by MRS or RES
input. During an error, the minor fault signal (LF) is
given to the open collector output. Allocate the
terminal used with any of Pr. 190 to Pr. 195
(output terminal function selection).
