When the inverter is ready to operate, the output
of the operation ready signal (RY) is ON. (It is also
ON during inverter running.)
When the inverter output frequency rises to or
above the [
Pr. 13 Starting frequency
] setting, turn
ON the output of the inverter running signal
(RUN). During an inverter stop, DC injection brake
operation, start time tuning or pre-excitation, the
output is OFF.
For the RUN2 signal, the output is ON while the
inverter is running and the start signal is ON. (The
RUN2 signal shuts OFF output when a fault occur
and the MRS signal is ON.)
For the RUN3 signal, the output is ON while the
inverter is running and the start signal is ON.
The RUN2 and RUN3 signals are ON when the
start command is ON and even during pre-
excitation with "0" set in speed command. (Note
that the RUN2 signal turns OFF during pre-
excitation by turning the LX signal ON.)
The RY2 signal turns ON at the start of pre-
excitation. The signal is ON while pre-excitation is
activated even during an inverter stop. The signal
turns OFF while the output is shut off (MRS
signal).
When using the RY, RY2, RUN2 and RUN3 signals, assign
functions to [
Pr. 190 to Pr. 196 Output terminal selection
function
] referring to the table below.

* 1 Pre-excitation is made when the start signal is ON and frequency command is 0Hz.
* 2 This signal turns OFF during power failure or undervoltage.
* 3 There is a delay of 100ms (500ms for the 75K or more) when the signal is ON.
* 4 This signal turns ON during servo ON (LX signal is ON) under position control.
