F5-69 AI3 sets jumping point
F5-70 AI3 sets jump amplitude
Analog quantity inputs AI1 to AI3 have the function of setting value jump. The skip function refers to setting the
analog quantity corresponding to changes in the upper and lower sections of the skip point.
The value is fixed to the value of the jumping point.
Example:
The voltage of analog quantity input AI1 fluctuates up and down 5.00V, ranging from 4.90V to 5.10V. the
minimum input 0.00 V of AI1 corresponds to 0.0 % and the maximum input 10.00V corresponds to 100. %. And then
the detected AI1 corresponds to a fluctuation of 49.0 % ~ 51.0 %.
Setting AI1 set jumping point F5 - 65 to 50.0 % and setting AI1 set jumping amplitude F5 - 66 to 1.0 %, the
corresponding setting of the obtained AI1 input after the jump function processing is fixed to 50.0 %, AI1 is converted
into a stable input and the fluctuation is eliminated.
F6 - 00 starting operation mode
0: direct starting
If the starting DC braking time is set to 0, the frequency inverter will start operating from the starting frequency.
If the starting DC braking time is not 0, DC braking will be performed first, and then operation will start from the
starting frequency. Suitable for small inertia load, where the motor may rotate during start - up
1: speed tracking and restarting
The frequency inverter first judges the speed and direction of the motor, then starts at the tracked frequency of
the motor, and during rotation the motor starts smoothly and without impact. It is suitable for the restart of large
inertia load with instantaneous power failure. In order to ensure the performance of speed tracking and restart, it is
necessary to accurately set the f1 parameters of the motor.
2: The pre-excitation starting of the asynchronous machine
Is only valid for the asynchronous motor, which is used to establish the magnetic field before the motor runs.
Refer to the description of function codes F6 - 05 and F6 - 06 for pre-excitation current and pre-excitation time.
If the pre-excitation time is set to 0, the frequency inverter cancels the pre-excitation process and starts from the
starting frequency. If the pre-excitation time is not 0, the motor can be pre-excited before starting, which can improve
the dynamic response performance of the motor.
F6 - 01 speed tracking method
In order to complete the speed tracking process in the shortest time, select the way that the frequency inverter
tracks the motor speed:
0: starting from shutdown frequency
This method is usually used to track down from the frequency of power failure.
1: starting from zero speed
Track up from zero frequency, and use it in case of power failure for a long time before starting.
2: starting from the maximum frequency
Track down from the maximum frequency and use the general power generating load.
