Run Signal - Hitachi CONVENTION 14 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).
Option Terminal
Code Symbol
00 RUN Run Signal
Valid for inputs: 11, AL0 – AL2
Required settings (none)
Notes:
The inverter outputs the [RUN] signal
whenever the inverter output exceeds the start
frequency specified by parameter B082
start frequency is the initial inverter output
frequency when it turns ON.
The example circuit for terminal [11] 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.
