Tried to increase the current usage during Anti-Slip operation.
(11)Torque Speed Kp:3000
Torque Speed Ki:80
Speed Err Limit:1000
These parameters are used for PID adjustment. If the acceleration is too aggressive, please
reduce these three parameters at the same time, vice versa. Please change the Torque Speed
Kp every 1000 units, Torque speed Ki every 100 units and Speed Err limit every 500 units.
Note: Thermistor is optional. Default to KTY84-130/150 or KTY83-122
When controller temp item shows 246 in monitor screen of user program, it is normal. This
item is only useful for internal calculation for MCU.246 is about 11 degrees in environment.
4.4 How to use Identification angle operation for KHS-I controller
We must do Identification angle operation before running motor for all KHS controllers. The
Identification angle operation can be done in PC program or Android App(Tablet or Cell Phone).
KHS-I controller is designed for BLDC motor with three hall sensors. By default, the speed
sensor type is set at 2 from factory setting for KHS-I controller.
1,Please hook up the controller for identification angle operation according to the wiring
diagram below. Please make sure there is no load on the motor shaft before starting the
programming. The KHS-I is designed by opto-isolated technology. We specify 10-30V for power
supply pin7 vs pin6 which must be isolated from main battery pack B+/B-.Usually customers
can use 12V car battery or 12V Isolated type DCDC converter for this purpose.
