The following 9 functions are handled by the software in the built-in
microcontroller:
Table 4-14 Operation by Software
Item Description
Run/Stop
Controls running and stop of the
in~erter.
Emergency stop at fault When a fault occurs, the software trips the
m~erter
under certain conditions
Automatic restart
When fault occurs, the mverter determines if the automatic restart may be
possible. If possible, it executes the automatic restart program.
Voltage/Frequency (V/F)
Selects and controls one of 16 V/F patterns.

Stall detection When the main Circuit current (IFB) exceeds the stall activation le~el,
the software functions to pre~ent the stall.
Overload detection
I
When the main Circuit current (I FB) exceeds the overload detection level,
the software starts calculating the overload.
Deceleration limit
When the regenerated power from the motor is so large as to increase
the DC voltage
abo~e
the set value during deceleration, the software
extends the deceleration time.
Momentary power When an mstantaneous power failure occurs, the software prevents a
failure contrOl stall of the motor
by
controlling the output frequency of the inverter
i
in harmony with the voltage drop of the DC main Circuit, to assure
i
smooth operation upon recovery of the power,
Monitor control Displays data on the digital indicator.
