Run Signal - Hitachi L200 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 ground).

Notes:
•
The inverter outputs the [RUN] signal whenever the
inverter output exceeds the start frequency specified
by parameter B082. The start frequency is the initial
inverter output frequency when it turns ON.
•
The example circuit for terminal [12] 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.
