 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's output frequency reaches Pr. 13 Starting frequency (0.01Hz under IPM motor control) or higher, the
inverter running signal (RUN) is output. During an inverter stop or DC injection brake operation, the output is OFF.
When using the RY and RUN signals, assign functions to Pr.190 or Pr.192 (output terminal selection function) referring to the
table below.

Output is shutoff in conditions like a fault and when the MRS signal is ON.
REMARKS
 The RUN signal (positive logic) is assigned to the terminal RUN in the initial setting.
 During IPM motor control, the RUN signal is output about 100ms after turning ON the start command (STF, STR). The delay is
due to the magnetic pole detection.
