Starting frequency
Stopping frequency
Output frequency
The starting frequency can be set to reserve the torque at
startup and can be sustained until the magnetic flux of the
motor is being established.
Frequency: This function sets the frequency at startup.
Setting range: 0.1 to 60Hz
Holding time: This function sets the holding time
during which the start frequency is sustained at startup.
Set values: 0.1 to 10.0 seconds

The holding time does not apply at the time of switching
between forward and reverse.

The holding time is not included in the acceleration time.

The holding time also applies when pattern operation
(C21) is selected. The holding time is included in the
timer value.
This function sets the frequency at stop.
Setting range: 0.0 to 60.0Hz
The operation does not start when the starting frequency
is less than the stopping frequency or when the setting
frequency is less than the stopping frequency.
This function adjusts the carrier frequency, correct
adjustment of which prevents resonance with the
machine system, reduces motor and inverter noise, and
also reduces leakage current from output circuit wiring.

0.75 to 6kHz
Carrier frequency Low High
Motor noise High Low
Output current waveform Bad Good
Leakage current Small amount Large amount
Noise occurrence Extremely low High
The tone of motor noise can be altered when the carrier
frequency is 7kHz or lower. Use this function as
required.
Setting range: 0 , 1, 2 , 3
Monitor data (e.g.,output frequency, output current) can
be output to terminal FMA as a DC voltage. The amplitude
of the output can also be adjusted.
This function adjusts the voltage value of the monitor
item selected in F31 when the monitor amount is 100%.
A value from 0 to 200 (%) can be set in 1% steps.
Setting range: 0 to 200%
This function selects the monitor item to be output to
terminal FMA.

Notes:
1. Reducing the set value adversely affects the output current
waveform (i.e., higher harmonics), increases motor loss, and
raises motor temperature. For example, at 0.75 kHz, reduce
the motor torque by about15%.
2 Increasing the set value increases inverter loss and increases
the inverter temperature.
