PWM on the motor generated without phase shift

[dvogureckiy99]

My problem is phase voltages (PWM) on the motor generated without phase shift.
I tried set gMotorVars[mtrNum].IqRef_A = 2 always so, but nothing happen.
see the picture below:

after increasing the voltage to gMotorVars[mtrNum].IqRef_A = 5

• the PWM of phase 2 has shifted a little:
• the current rose to 0.7 A constant value (the engine is designed for high currents)
• the engine began to warm up strongly and the smell of burning appeared
  

after analyzing the PC program for sending commands to the master-board, it turned out that it sends exactly the current value: gIqFeedforward_A[HAL_MTR2] as robot_if.GetMotor(i).SetCurrentReference(cur)
