Function assignment of external terminal and control

PARAMETERS
*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 higher) when the signal is ON.
*4 This signal turns ON during servo ON (LX signal is ON) under position control.
*5 Output is shutoff in conditions like a fault and when the MRS signal is ON.

⋅ 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, the output of the inverter running
signal (RUN) is turned ON. 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. (For the RUN2 signal, the
output is OFF when the inverter protective function is
activated 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).

REMARKS
For pre-excitation by pre-excitation signal (LX), the RY2 signal
turns ON when 100ms has elapsed after LX signal turn ON
(500ms for the 75K or higher).
