NOTES When the start signal is turned OFF before the time set in Pr. 137 has passed after the start signal is
turned ON, the inverter does not start and the MC1 signal is turned OFF after the time set in Pr. 254
has passed.
If the start signal is turned ON again before the time set in Pr. 254 has passed, the inverter immedi-
ately starts outputting.
At inverter reset, the status of the MC1 signal is held and operation of the magnetic contactor is
not performed.
When the inverter stops the output due to, for example, the Output stop (MRS) signal, the MC1
signal is turned OFF after the time set in Pr. 254 has passed.
During the stop, turning ON the External DC injection brake operation start signal (X13) and Pre-
excitation/servo ON signal (LX) turns ON the MC1 signal.
To avoid inverter reset when starting to supply power to the main circuit when power is already
supplied only to the control circuit, set 100 or more in Pr. 30. (For the separated converter type,
setting Pr. 30 of the converter unit is also required.)
When supplying power to the main circuit is started when power is supplied only to the control
circuit, there is a little waiting time before starting.
Repeated operation of the magnetic contactor due to frequent start and stop or activation of the
protective function may shorten the inverter life.
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) and
Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions. Set parame-
ters after confirming the function of each terminal.
