6.3.6.5.3 Forward-Reverse Profiles
Figure 6-10 Forward Reverse Control ProfilesForward-Reverse control profiles can be configured by setting REF_PROFILE_CONFIG to 11b. Forward-Reverse profiles feature direction change through adjusting the duty command. DUTY_C configures duty command at which the direction will be changed. The Forward-Reverse speed profile can be used to eliminate the separate signal used to control the motor direction.
Note: The direction change functionality through DIR pin and DIR_INPUT bits are disabled in forward reverse profile mode.
- DUTY_OFF1 configures the duty command below which the reference will be REF_OFF1.
- DUTY_OFF1 and DUTY_ON1configures a hysteresis around reference control input REF_CLAMP1 and REF_OFF1 as shown in Figure 6-10.
- DUTY_CLAMP1 configures the duty command till which reference will be constant. REF_CLAMP1 configures this constant reference between DUTY_OFF1 and DUTY_CLAMP1. DUTY_CLAMP1 can be placed anywhere between DUTY_OFF1 and DUTY_A.
- DUTY_A configures the duty command for reference REF_A. The reference changes linearly between DUTY_CLAMP1 and DUTY_A. DUTY_A to DUTY_E has to be in the same order as shown in Figure 6-10.
- DUTY_B configures the duty command above which MCF8329A-Q1 will be in off state. The reference remains constant at REF_A between DUTY_A and DUTY_B.
- DUTY_C configures the duty command at which the direction is changed
- DUTY_D configures the duty command above which the MCF8329A-Q1 will be in running state in the reverse direction. REF_D configures constant reference between DUTY_D and DUTY_E.
- DUTY_E configures the duty command above which reference changes linearly between DUTY_E and DUTY_CLAMP2.
- DUTY_CLAMP2 configures the duty command above which the reference will be constant at REF_CLAMP2. REF_CLAMP2 configures this constant reference between DUTY_CLAMP2 and DUTY_OFF2. DUTY_CLAMP2 can be placed anywhere between DUTY_E and DUTY_OFF2.
- DUTY_OFF2 and DUTY_ON2 configures a hysteresis around reference control input REF_CLAMP2 and REF_OFF2 as shown in Figure 6-10.
- DUTY_OFF2 configures the duty command above which the reference changes in the reverse direction from REF_CLAMP2 to REF_OFF2.
- DUTY_HYS configures the hysteresis during step change at DUTY_B and DUTY_D.
