The second acceleration time f500 0.0-3600s 10.0s can be switched through the terminal for the second set of acceleration times

The second deceleration time f501 is 0.0-3600s and 10.0s, which can be switched through the terminal for the second set of deceleration times

4.2.2.3 Motor protection parameters

Parameter Name Parameter Symbol Adjustment Range Default Value Function Description

Electronic thermal protection level 1 thr 10-100% (or A) 100% is based on the rated current of the frequency converter and needs to be adjusted according to the rated current of the motor (for example, if the rated current of the motor is 42% of the frequency converter, set it as 42%)

Electronic thermal protection level 2 f173 10-100% (or A) 100% second group electronic thermal protection level, which can be switched through terminals

Overload characteristic selection: aul 0=default, 1=constant torque, 2=variable torque 0 1=150% -60s (applicable to conveyors), 2=120% -60s (applicable to fans and pumps)

Electronic thermal memory f632 0=disabled, 1=enabled, 0. Save the accumulated overload value after power failure, and continue calculation after power on

Overload alarm level f657 10-100%. When 50% overload reaches this level, a flashing alarm will sound, and an alarm signal can be output through the output terminal

Motor 150% overload detection time f607 10-2400s 300s When the motor current reaches 150%, delay the time and trip

Stall protection level 1 f601 10-199% (or A), 200=disable 150% overcurrent stall protection threshold, automatic frequency reduction when exceeding this value

4.2.2.4 Special functional parameters

Parameter Name Parameter Symbol Adjustment Range Default Value Function Description

Automatic restart control f301 0=disabled, 1=instantaneous power outage restart, 2=ST terminal control 0 1=detect motor speed after instantaneous power outage, smooth restart after power restoration

The retry count f303 0=disabled, 1-10 times 0. Automatic retry after overcurrent, overvoltage, etc. tripping, retry interval increases from 1s to 10s

Dynamic braking selection f304 0=disabled, 1=enabled (resistance protection), 2=enabled. After enabling 0, the braking resistor needs to be connected for rapid deceleration or regenerative load scenarios

The resistance value of the braking resistor f308 1.0-1000 Ω should be consistent with the actual resistance value of the connected braking resistor depending on the model

Overvoltage limit operation f305 0=enabled, 1=disabled, 2=rapid deceleration, 2=automatic frequency adjustment when DC voltage is too high during deceleration to avoid overvoltage tripping

PID control selection f360 0=disabled, 1=process type, 2=speed type 0 is used for closed-loop control of flow, pressure, etc., and feedback signals (such as 4-20mA at VIC terminal) need to be coordinated

The PID setpoint fpid f368-f367 (Hz) is the target value of the 0.0Hz PID control, which can be adjusted through the panel or communication

4.3 Parameter Setting Operation Steps (Taking Adjusting Thr as an Example)

Switching mode: Press the MODE key, the display screen will show "auh" (history function), rotate the setting dial to select "thr".

Read current value: Press the set dial button, and the display screen will show the current value (such as 100%).

Adjust parameters: Rotate the dial setting to the target value (such as 42%).

Confirm save: Press the set dial button, and the display screen will alternately show "42" and "thr", indicating successful save.

Return to monitoring: Press the MODE button twice to return to standard monitoring mode (display output frequency).

4.4 Example of Common Operating Mode Configuration

4.4.1 Panel operation+setting dialing frequency (default configuration)

Cmod=1 (panel command mode)

Fmod=0 (set dial 1, power off and save)

Operation: Rotate to set the dialing frequency, press RUN to start, press STOP to stop.

4.4.2 Terminal operation+external potentiometer frequency

CMOD=0 (Terminal Command Mode)

Fmod=1 (VIA terminal input)

Wiring: VIA-CC indirect external potentiometer (1k-10k Ω)

Operation: Short circuit F-CC starts, disconnect F-CC stops, adjust potentiometer to change frequency.

4.4.3 Preset speed operation (3-speed)

CMOD=0 (Terminal Command Mode)

Fmod=14 (sr0 preset speed)

Parameter settings: sr1=20Hz, sr2=30Hz, sr3=50Hz (set 3-stage speed)

Wiring: S1-CC (speed 1), S2-CC (speed 2), S3-CC (speed 3)

Operation: Short circuit corresponding terminal selection speed, short circuit F-CC starts.
