12. (M) Item and Output Signal for Monitoring
12.6 Output terminal function selection
• The Operation ready 2 (RY2) signal turns ON when the pre-excitation starts. The signal is ON during pre-excitation even
while the inverter is stopped. The signal is OFF during the inverter output shutoff.
NOTE
• When pre-excitation works with the Pre-excitation (LX) signal ON, the RY2 signal turns ON after 100 ms from the time the LX
signal turns ON. (When online auto tuning at start-up is selected ( Pr.95 = "1"), the time the signal turns ON is delayed by the
tuning time.)
• The ON/OFF state of each signal according to the inverter operating status is shown in the matrix below.
*1 When the start signal is ON and the frequency command is 0 Hz, such state is designated as "during zero speed control".
*2 The signal is OFF during power failure or undervoltage.
*3 The signal turns ON after 100 ms from the time the LX signal turns ON.
*4 This means the state during a fault occurrence or while the MRS signal is ON, etc.
*5 The signal is OFF while power is not supplied to the main circuit.
• To use the RY, RY2, RUN, RUN2, or RUN3 signal, set the corresponding number selected from the following table in any
of Pr.190 to Pr.196 (Output terminal function selection) to assign the function to an output terminal.
