2) Checking the inverter operating status
by the inverter operation ready
completion signal
Operation ready signal (RY signal) is
output when the inverter power is on
and the inverter becomes operative.
Check if the RY signal is output after
powering on the inverter.
3) Checking the inverter operating status
by the start signal input to the inverter
and inverter running signal.
The inverter running signal (RUN signal) is output when the inverter is running
(RUN signal is assigned to terminal RUN in the initial setting).
Check if RUN signal is output when inputting the start signal to the inverter
(forward signal is STF signal and reverse signal is STR signal). For logic
check, note that RUN signal is output for the period from the inverter
decelerates until output to the motor is stopped, configure a sequence
considering the inverter deceleration time
4) Checking the motor operating status by the start signal input to the inverter
and inverter output current detection signal.
The output current detection signal (Y12 signal) is output when the inverter
operates and currents flows in the motor. Check if Y12 signal is output when
inputting the start signal to the inverter (forward signal is STF signal and
reverse signal is STR signal). Note that the current level at which Y12 signal is
output is set to 150% of the inverter rated current in the initial setting, it is
necessary to adjust the level to around 20% using no load current of the motor
as reference with Pr. 48 "output current detection level".
For logic check, as same as the inverter running signal (RUN signal), the
inverter outputs for the period from the inverter decelerates until output to the
motor is stopped, configure a sequence considering the inverter deceleration
time.
