So output range of Sin/Cosin speed sensor is 3-1.1V=1.9V to 3+1.1V=4.1V.(1.9V-4.1V).
We set the Line hall high err at 972.It is about 4.75V.The line hall low err at 50.It is about 0.25V.
So as long as the output is in the range from 0.25V to 4.6V.It should be good. The controller will
not report hall error code in this case. We need to go to Step 5 to do the identification angle
operation directly. If the identification angle operation is finished successfully, there is no
problem. The line hall zero and amplitude values are correct. Otherwise we need to measure
the line hall zero point and hall amplitude by manual.
Because the previous value is just from the calculation in theory. We think the 5V could be a
little lower than 5V.There is 5% deflection for 5V source and 2% deflection for hall amplitude.
Here is the solution.
1),So please make sure the sensor connector is connected between controller and motor. Then
please measure the output of Sin or Cosin output when you rotate the motor manually and
slowly. Please let us know the min and max output of this port.
2),Then please calculate the value.Zero-Crossing point=(Vmin+Vmax)/2.
Amplitude=Zero-crossing point-Vmin=Vmax-Zero-Crossing point.
3),Then we need to fill the correct Zero-crossing point and Amplitude again.
Please make sure the 5V is from the controller for Sin/Cosin sensor.
We need to click Write button in the user program each time when you change the settings. And
we need to do identification angle operation each time after you changed the settings. We need
to reset the power supply each time when we change the settings and do the identification
angle operation.
We may wait a few seconds to reset the power supply after change the settings.
5,Please fill 170 in the identification angle item. And please click the write button. The user
program will give a pop-up window which show the Write operation is successful. Please quit
from the user program. Please turn off the power supply.
6,Please turn on the power supply after the power supply is off for a few seconds. The motor
shaft will try to run on directions randomly. It is normal because the controller is doing
Identification angle operation.
7,Please wait about 2-3 minutes.
8,If the identification angle operation is finished, the motor will stop completely. And you will see
reset error message in the monitor screen of user program. You can see the error message in
monitor screen of user program for KHS-I controller also.
9,Please turn off the power supply again. Please wait about a few seconds to turn on the power
supply one more time.
10,Please try to connect the controller to user program again. You will see 85 in the
identification angle item. That is to say, the controller identification angle operation is successful.
You can use the KHS-IPS controller to drive the motor now.
11,As long as it is not reset error code, the value in identification angle will not go back to
85.The value is always at 170.That is to say, the controller is still in the processing of
identification operation.
12,Please don't try to write 85 in the identification angle or reset the power supply if you don't
see any error codes.
