Function assignment of external terminal and control
(2) Drive unit operation ready signal (RY, RY2 signal) and drive unit running (RUN signal)
When the drive unit is ready to operate, the output of the operation ready signal (RY) is ON. (It is also ON during drive unit
running.)
When the output speed of the drive unit rises to or above 1r/min, the drive unit running signal (RUN) is turned ON. During
an drive unit stop or DC injection brake operation, the output is OFF.
The RY2 signal turns ON when the pre-excitation starts.
The signal stays ON as long as pre-excitation is activated even if the drive unit is in a stop status. The output shutoff signal
(MRS) is OFF. (Refer to page 95)
When using the RY, RY2 and RUN signals, assign functions to Pr. 190 or Pr. 192 (output terminal selection function) referring to
the table below.

REMARKS
The RUN signal (positive logic) is assigned to the terminal RUN in the initial setting.
When the start command (STF, STR) is turned ON during PM motor control, the RUN signal is output after Pr. 736
Electromagnetic brake interlock time plus about 100ms. This delay is caused by the electromagnetic brake interlock and magnetic
pole detection. (Refer to page 96)
