DRV8353RS-EVM: Gate driver fault

Dear sir,

i have hub motor and Launchpad-F280025c

DMC-2

Added, as I set the v/f parameter and reduce and increase the dacCMPValL and dacCMPValH value , we are not getting overcurrent fault ,under the default max_current setting --> 7amp,

we able to spin the motor  at following speed reference.

motorVars_M1.speedRef_Hz = 10.0f; // Hz
motorVars_M1.speedRef_rpm = 100.0f; // rpm

but as we increase speed further , motor start spinning fast for few minutes ,after that we got the GDF fault and voltage offset parameter become changes to 1.5,1.5,1.5 , that is very confusing (I have change 5 drv83 IC  but not get any solution for this why this happening)

motorVars_M1.speedRef_Hz = 39.0f; // Hz
motorVars_M1.speedRef_rpm = 100.0f; // rpm

v/f profile

// the minimum rotation frequency if the motor (Hz)
#define USER_MOTOR1_FREQ_MIN_Hz (9.0f) // Hz

// the maximum/base rotation frequency of the motor (Hz)
#define USER_MOTOR1_FREQ_MAX_Hz (110.0f) // Hz

// V/f Profile Parameters for open-loop in build level 2
// the low frequency f_low of V/f profile, in Hz,
// set to 10% of rated motor frequency
#define USER_MOTOR1_FREQ_LOW_Hz (5.0f) // Hz

// the high frequency f_high of V/f profile, in Hz,
// set to 100% of rated motor frequency
#define USER_MOTOR1_FREQ_HIGH_Hz (110.0f) // Hz

// the minimum voltage V_min of V/f profile,
// the value is suggested to set to 15% of rated motor voltage, in Volt.
#define USER_MOTOR1_VOLT_MIN_V (1.0f) // Volt

// the maximum voltage, V_max of V/f profile,
// the value is suggested to set to 100% of rated motor voltage, in Volt
#define USER_MOTOR1_VOLT_MAX_V (24.0f) // Volt

Please me to short it out ....
