Section VI. Function Parameter Description
F44: Pick up selection factory setting: 0
This parameter is used for selecting pick up mode.
0: Invalid. Start from 0Hz or starting frequency.
1: Pick up when power down. When inverter power down instantly and
restarts, motor keeps running at the current speed and direction.
2: Pick up when start. When power on, inspects the motor speed and
direction, runs at the current speed and direction.

F45: Electronic thermal relay protection selection factory setting: 1
This function is to protect the motor when overheat happens to the motor
without other thermal relays. Inverter’s some parameters calculate the
motor’s high temperature, meanwhile estimating whether the current would
make the motor overheat or not. Inverter stops output and display the
protection information when electronic thermal relay protection function is
valid.

1: Valid

Section VI. Function Parameter Description
The current is set by the inverter when diagnosing the over heat of the
motor. The protection takes effect in 1 minute when the current equals to the
product of the motor’s rated current multi-pled the value of F46, that is the
actual current is F46 times of rated current.
The factory value is 150% for type G.
F47: Power consuming braking selection factory setting: 0
0: Invalid
1: Safe mode
Only during the deceleration and inspection of DC bus voltage higher
than the set value, this function takes effect.
2: General mode
Under any status, it takes effect only inspecting DC bus voltage higher
than the set value.
Over voltage or over current probably occurs when inverter instantly
decelerates or the load’s fluctuation is big. This phenomenon occurs much
easily when the load inertia is relatively big. Inside inverter DC high voltage
is inspected over certain value, power consuming brake can be realized by
output brake signal via external brake resistor.
F48: Fault reset times factory setting: 0
During running, if over current (OC) or over voltage (OU) occurs, this
function makes inverter automatically reset and run at the setting state
when there was no fault. Reset times are based on this parameter, at most
10 times can be set. When it is “0”, automatic reset function is invalid after
fault occurrence. But if DC main circuit’s main relay fault MCC or lack
voltage LU fault occurs, the automatic reset is not limited by this.
Restart and runs normally after fault for over 36s, the previous fault rest
times is set.
Fault last for over 10s then the fault reset function could not be executed.
F49: Fault reset time factory setting: 1.0s
This function is for setting time interval of fault auto-reset. Inverter stops
after fault, it takes more time.
For no-fault inspection than fault reset time, then fault auto-resets.
F50: Program running mode factory setting: 0
0: Single circulation.
1: Continuous circulation.
2: Single circulation, continuous running at step 7 speed, and stop when
receiving STOP command.
The 3 program running modes are as below:
e.g. 1 Single ciruculation
