Initialization (shipment status at factory) input
The output frequency setting, base and maximum frequencies,
control method, motor constant, acceleration or deceleration time,
manual torque boost setting, and electronic thermal setting are
changed in batch.
The acceleration or deceleration time or selection of two-stage
accration or deceleration is changed by turning the contact ON.
The inverter stops and the motor stops free run
FRS functions when the contact is opened. (European version)
External trip input signal (The contact is open.)
Restart prevention when the power is turned on in the RUN
state (The contact is open.)
Switch signal from the commercial power source to inverter
drive (Note: When the terminal is used, a trip is also conceled.)
The data of all funcitons except for output frequency setting is
locked. See 12-9 [F-25].
Analog input voltage-current switching (When the contact is ON,
current input signal to OI-L is acrive.)
Trip or alarm signal is reset.
When the contact is turned ON, the operation is accelerated.
(Available only when the frequency command is sent
to the operator.)
When the contact is turned ON, the operation is decelerated.
(Available the frequency command is sent to the operator.)
