(M) Monitor display and monitor output signal
● When using the RY, RY2, RUN, RUN2 and RUN3 signals, refer to the following and assign the
functions by Pr. 190 to Pr. 196 (output terminal function selection).
Tab. 5-143: Assignment of the signals
NOTE The RUN signal (positive logic) is assigned to the terminal RUN in the initial status.
Forward rotation and reverse rotation signals (Y30 and Y31)
Fig. 5-167:
● Under vector control, a Forward rotation output (Y30) signal or Reverse rotation output (Y31)
signal is output according to the actual rotation of the motor.
● During pre-excitation (zero speed, servo lock) under speed control or torque control, Y30 and Y31
are OFF. Note that during servo lock under position control, the output is according to the motor
rotation, the same as during operation.
● To use the Y30 signal, set "30 (positive logic) or 130 (negative logic)" in any of Pr. 190 to Pr. 196
(output terminal function selection) to assign the function to the output terminal.
● To use the Y31 signal, set "31 (positive logic) or 131 (negative logic)" in any of Pr. 190 to Pr. 196
(output terminal function selection) to assign the function to the output terminal.
NOTES Always OFF under V/F control, Advanced magnetic flux vector control, Real sensorless vector con-
trol, and PM sensorless vector control.
If the motor is rotated by an external force or other cause while the inverter is stopped, Y30 and
Y31 stay OFF.
