Figure 8-14. Linear Reference Profile

Linear reference profile can be configured by setting REF_PROFILE_CONFIG to 01b. Linear reference

profile features speed/power references which change linearly between REF_CLAMP1 and REF_CLAMP2 with

different slopes which can be set by configuring DUTY_x and REF_x combination.

• DUTY_ON1 configures the duty command above which MCT8317A starts driving the motor (to speed/power

reference set by REF_CLAMP1) when the current speed/power reference is zero. When current speed/power

reference is zero and duty command is below DUTY_ON1, MCT8317A continues to be in off state and motor

is stationary.

• DUTY_OFF1 configures the duty command below which the speed/power reference changes to REF_OFF1.

• DUTY_CLAMP1 configures the duty command till which speed/power reference will be constant.

REF_CLAMP1 configures this constant speed/power reference between DUTY_OFF1 and DUTY_CLAMP1.

• DUTY_A configures the duty command for speed/power reference REF_A. The speed/power reference

changes linearly between DUTY_CLAMP1 and DUTY_A.

• DUTY_B configures the duty command for speed/power reference REF_B. The speed/power reference

changes linearly between DUTY_A and DUTY_B.

• DUTY_C configures the duty command for speed/power reference REF_C. The speed/power reference

changes linearly between DUTY_B and DUTY_C.

• DUTY_D configures the duty command for speed/power reference REF_D. The speed/power reference

changes linearly between DUTY_C and DUTY_D.

• DUTY_E configures the duty command for speed/power reference REF_E. The speed/power reference

changes linearly between DUTY_D and DUTY_E.

• DUTY_CLAMP2 configures the duty command above which the speed/power reference will be constant

at REF_CLAMP2. REF_CLAMP2 configures this constant speed/power reference between DUTY_CLAMP2

and DUTY_OFF2 . The speed/power reference changes linearly between DUTY_E and DUTY_CLAMP2.

• DUTY_ON2 configures the duty command below which MCT8317A starts driving the motor (to speed/power

reference set by REF_CLAMP2) when the current speed/power reference is zero. When current speed/power
