a) I am using lab 1b and motor is not getting start any special attention need other than labs user guide ? because if I run motor with normal V/f PWM pattern motor is getting start. 

Please take a look at the lab user's guide, and set the following parameters according to the motor you used.

#define USER_MOTOR_FREQ_LOW (10.0) // Hz - suggested to set to 10% of rated motor frequency
#define USER_MOTOR_FREQ_HIGH (100.0) // Hz - suggested to set to 100% of rated motor frequency
#define USER_MOTOR_FREQ_MAX (120.0) // Hz - suggested to set to 120% of rated motor frequency
#define USER_MOTOR_VOLT_MIN (3.0) // Volt - suggested to set to 15% of rated motor voltage
#define USER_MOTOR_VOLT_MAX (18.0) // Volt - suggested to set to 100% of rated motor voltage
