(P 00) Max. Frequency: Setting the maximum inverter frequency.
(P 01) Max. Voltage Frequency: Setting the maximum voltage frequency when the inverter
operates at the maximum voltage.
Please adjust the value depending on the motor input power if needed.
(P 02) Max. Voltage: Setting the maximum inverter voltage.
(P 03) Mid-point Frequency: Setting the mid-point frequency of the V/F curve.
The setting value should be same or higher than the minimum frequency.
(P 04) Mid-voltage: Setting the mid-voltage of the V/F curve.
(P 05) Minimum Frequency: Setting the minimum inverter frequency for output.
(P 06) Minimum Voltage: Setting the minimum inverter voltage for output.
(P 07) Acceleration Time: Setting the acceleration time from 0Hz to 50/60Hz.
(P 08) Deceleration Time: Setting the deceleration time from 50/60Hz to 0Hz.

(C 10) Auto Reset: If the alarm occurs, the system will try to reset the system depending
on the set value. If the alarm is not resolved after the reset period, the system will stop all operation.

(P 09) Stop Mode: Setting the stop method of the inverter.
- Ramp to stop: It is a general stop mode. If there is no extra settings applied,
the motor decelerates down from Max.Hz to 0Hz.
- Free run: When the operation command is off, the inverter output turns off.
(P 10) Fan Control: Setting the fan status during the inverter operation.
(P 11) PWM Carrier fre.: If the noise level comes from the inverter is higher than
normal condition, please decrease the carrier frequency value.
