F00.08
Lower limit
frequency
Setting range: 0.00Hz ～
F00.08
Default value:
0.00Hz
The upper and lower limit frequency is the running maximum and minimum
frequency of the motor according to the requirements of production process.
F00.09

Setting range: 0.00Hz ～
F00.07
Default value:
50.00Hz
When the X frequency reference (F00.02) is selected as a digital reference, the
function code value sets the initial value for the frequency setting of the inverter.
F00.10
Run direction
Setting range: 0～2
Default value: 0
0: positive
After power on, the inverter runs in the actual direction.
1: reverse
Be used to change the running direction of the motor.
In some cases, the motor runs reversely. It is complicated to change the wiring of
the motor. The function code can bring debugging convenience.
2: prohibit reverse
For some devices, reverse running may cause damage to the equipment, this
function can be used to prohibit reverse running.
For example, when the run direction selection (F00.10) selects reverse and the
reverse running of the terminal command channel is valid, the motor actually
rotates forward.
F00.11
Carrier frequency
Setting range: 1.0 ～
15.0kHz
Default value:
Depend on model
This function adjusts the carrier frequency of the inverter. Adjusting the carrier
frequency can reduce the motor noise, avoid the resonance point of the
mechanical system, and reduce the line-to-ground leakage current and the
interference caused by the inverter.
When the carrier frequency is low, the high output current harmonic component,
motor loss and temperature increase.
When the carrier frequency is high, the motor loss and the motor temperature
decrease, but the inverter loss, temperature and interference increase.
Adjusting the carrier frequency will have an impact on the following performance:
