It is used to define the source of frequency upper limit. The frequency upper limit can be sourced from
either digital setting (P0-12) or analog input. When the analog input is used to set the frequency upper limit,
100% of analog input setting is relative to P0-12.
Notice:
Upper frequency limit should exceed than the maximum frequency.
Output frequency should not exceed upper frequency limit.
P0-12
Frequency upper limit
Factory default
50.00Hz
Setting range
P0-14 (frequency lower limit) ~ P0-10 (maximum frequency)
P0-13
Frequency upper limit
offset
Factory default
0.00Hz
Setting range
0.00Hz ~ P0-10 (maximum frequency)
When the frequency source upper limit is analog value or HDI pulse, P0-
13 is used as the setting value’s
offset. The combination of this offset frequency and P0-12 is used as the final setting value of frequency
upper limit.
P0-14
Frequency lower limit
Factory default
0.00Hz
Setting range
0.00Hz ~ P0-12 (frequency upper limit)
If the reference frequency is lower than frequency lower limit, the inverter can stop, or run with lower limit
frequency, or run at zero speed, which is set by P8-14.
P0-15
Carrier frequency
Factory default
Model depend
Setting range
1.0kHz ~ 16.0kHz
Carrier frequency will affect the noise of motor and the EMI of inverter.
If the carrier frequency is increased, it will cause better current wave, less harmonic current and lower
noise of motor.
Notice:
The factory default is optimal in most cases. Modification of this parameter is not recommended.
If the carrier frequency exceeds the factory default, the inverter must be derated because the
higher carrier frequency will cause more switching loss, higher temperature rise of inverter and
