SET
2nd function
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.
CH1
Two-stage acceleration
The acceleration or deceleration time or selection of two-stage
or deceleration
accration or deceleration is changed by turning the contact ON.
FRS
Free run stop
The inverter stops and the motor stops free run
FRS functions when the contact is opened. (European version)
EXT
External trip
External trip input signal (The contact is open.)
USP
Power-ON restart
Restart prevention when the power is turned on in the RUN
prevention
state (The contact is open.)
CS
Commercial power source
Switch signal from the commercial power source to inverter
switching
drive (Note: When the terminal is used, a trip is also conceled.)
SFT
Terminal software lock
The data of all funcitons except for output frequency setting is
locked. See 12-9 [F-25].
AT
