Retry function (b001: 02): The timing chart in case of selection is following.
(2) Instantaneous power failure during stop alarm output during under-voltage
Select yes/no of alarm output when instantaneous power failure or under-voltage occurs with b004.
Alarm outputs while control power of inverter remains.
• Alarm output at an instantaneous power failure and under-voltage during standstill.
Standard (Example 5-7).
Alarm signal performance when connecting DC voltage (P-N) to R0-T0 terminal. (Example 8-10).
(3) It is possible to use an output by assigning the signal (IP: 08) during instantaneous stop, by setting (UV: 09)
during under-voltage to an intelligent output terminal 11, 12(C021, C022) or alarm relay output terminal
(C026).
(4) If the instantaneous power failure time is longer than 1 second, please refer to the pages 4-48 Reset (RS).
After wait for t2 seconds
according to t0 < t1, restart.
