Run Signal - Hitachi SJ300 Series Instruction Manual

Run Signal

When the [RUN] signal is selected as an
intelligent output terminal, the inverter
outputs a signal on that terminal when it is
in Run Mode. The output logic is active
low, and is the open collector type (switch
to common).
Valid for
outputs:
Required
settings:
Notes:
• The inverter outputs the [RUN] signal
NOTE: The example circuit in the table above drives a relay coil. Note the use of a diode to
prevent the negative-going turn-off spike generated by the coil from damaging the inverter's
output transistor.
