quantity.

7 Detailed function specification

If users want to change the display range or error correction table headers, you can

achieve it by adjusting the output gain and bias of AO1.

When AO1 output voltage, the adjustment is as follows:

Analog output AO1(after revise)=output gain(F09.40)×analog output AO1(before

revise)+output bias(F09.41)×10V

When AO1 output current, the adjustment is as follows:

Analog output AO1(after revise)=output gain(F09.40)×analog output AO1(before

revise)+output bias(F09.41)×20mA

This function code will influence analog output during modify

processes.

The external reference signal and feedback signal usually carry some noise. those

noise signal can be filtered by setting the time constant of filter in F11.03 and

F11.04.The bigger the time constant is, the better the immunity capability, but

with a slow response. The shorter the time constant is, the faster the response, but

the immunity capability became weak.

The PID output filter time is the time of the filter for output frequency or torque,

the bigger time, the slower the response output.

The bigger of the proportion gain of Kp, the faster the response, but oscillation

may easily occur.

If only proportion gain Kp is used in regulation, the offset cannot be eliminated

completely. To eliminate the offset, please use the integral gain Ki to form a PI control

system. The bigger Ki is, the faster the response, but oscillation may easily occur if Ki is

big enough.

The sampling cycle T refers to the sampling cycle of feedback value. The PI D

Through F14.01 to F14.05, you can set the proportional gain and integral time of

Speed loop regulator, so as to change the speed response characteristic under

vector control mode.

The system dynamic response of speed loop can be faster if the proportional gain

is increased or the integral time is decreased. However, if the proportional gain is

too large or the integral time is too small, the system tends to oscillate.

The suggested adjusting way as below:

When the default parameter is not suitable, please fine adjust the parameters based

on the default value. Proportional gain is usually adjusted first. Under the

condition that the system is immune from oscillation, proportional gain can be

increased as big as possible. Then adjust integral time so that the system responds

fast and will not be over adjusted.

F15.07～F15.11 is the characteristic parameters of asynchronous motor, not

display on the nameplate, which need detected by auto-tuning. To achieved a

good control performance, please let the motor unload before start rotating

auto-tuning. For the asynchronous motor that cannot be disconnected from the

load, you can choose static auto-tuning or input the motor parameters manually.

Another way is just set F15.01 and used the default parameters in F15.01～

F15.11.Meantime,Choosing different type of G and P will also change the default

parameters in F15.01～F15.11.

After auto-tuning, the Drive will exit process automatically and the detected

values of the stator’s resistance, rotor’s resistance and the leakage inductance will

be saved in F15.07-F15.09.

In static auto-tuning mode, the value of No-load current and mutual inductive

reactance will not be detected. The user can input the related values with the

reference of the Motor factory data or the data on the motor test report. Without

related value, please adopt the Default value. Otherwise it may cause negative

influence on the performance of motor.

2: Rotating auto-tuning of Asynchronous motor

Rotating auto-tuning function is suitable for the applications which the load of

motor is lighter than 30% of the rated load or some kind of small inertia load.

Please try your best to disconnect the load of your motor and make the motor in

This parameter can correct the actual speed of the motor when the encoder not

installed on the axis of motor.

For example, when the encoder installed on a reduction gears with a 10:1 ratio,

you should set F16.02 as 10.000 so that get a correct feedback of actual motor

speed.

Because of encoder usually install on the axis of motor in closed-loop vector
