Hitachi hitachi series inverter Using Intelligent Output Terminals, Run Signal, Code Symbol

Using Intelligent Output Terminals
Run Signal
When the [RUN] signal is selected as an					1
intelligent output terminal, the inverter outputs [FW,RV]
a signal on that terminal when it is in Run					0

Notes:
• The inverter outputs the [RUN] signal whenever	Inverter output			RUN
the inverter output exceeds the start frequency	terminal circuit
specified by parameter B082. The 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			RY
from damaging the inverter’s output transistor.

Example for terminal [AL0], [AL1], [AL2] (requires output configuration see page 66):
