TMS320F28069M: BLDC motor rotates initially reverse then forward

Part Number: TMS320F28069M
Other Parts Discussed in Thread: DRV8312

Hello,

I am using F2806X ISO-CONTROLCARD [R0.4] with USBDockingStation [R3], I am running BLDC motor of 60V, 250W attached with wheel for two wheeler application with sample code which is located here  C:\ti\controlSUITE\development_kits\DRV8312-C2-KIT_v128\BLDC_Sensored. I have my own driver card with driver IC IR2104S which is similar to DRV8312 as used in DRV8312EVM Rev D board. DFuncDesired is directly controlled by throttle.

with LEVEL4 it is working fine. I am able to control the speed. there is only one small issue when I applied throttle motor rotates initially in counter clockwise direction then it rotates in clockwise direction. I have already read documents regarding the sample code. what is the possible reason?

one more question how can I apply more torque initially, I mean by using which variable?
