Kinco FD3&CD3 User Manual
The actual PI settings are Kvp[x], Kvi[x], Kpp[x], x=PI_Pointer.
There are 3 methods for changing PI_Pointer.
Method 1: The Gain Switch 0 and / or Gain Switch 1 function is configured to DIN. PI_Pointer is the
BCD code of
bit 0: Gain Switch 0
bit 1: Gain Switch 1
If only one bit is configured, the other bit is 0.
Example:
Figure 5-12: Din gain switch example
Gain Switch0=1, Gain Switch1= 0, then PI_Pointer=1, the valid PI gain settings are Kvp[1], Kvi[1] and
Kpp[1]
Method 2: If Method 1 is not applied, set PI_Switch(6069.09) to 1. Then, while the motor is rotating, set
PI_Pointer ti =0. As soon as Pos Reached or Zero Speed, set PI_Pointer to =1
This is the function for a system which needs different PI gain settings for rotation and standstill.
Information
Refer to the OUT function table in chapter 5.5.2 for Pos Reached and Zero Speed definition.
Method 3: If neither method 1 nor method 2 is applied, the PI_Pointer value can be defined by the user.
The default setting of 0 is highly recommended.
