92 / 117 page  Figure 7-95. ATQ_CTRL8 Register 7 6 5 4 3 2 1 0 KP[7:0] R/W-00000000b Table 7-79. ATQ_CTRL8 Register Field Descriptions Bit Field Type Default Description 7-0 KP[7:0] R/W 00000000b Proportional constant for tuning the auto torque PD control loop. 7.5.5.9 ATQ_CTRL9 (address = 0x27) [Default = 00h] ATQ_CTRL9 is shown in Figure 7-96 and described in Table 7-80. Read/Write Return to the Register Maps Table Figure 7-96. ATQ_CTRL9 Register 7 6 5 4 3 2 1 0 RSVD KD[3:0] R/W-0000b R/W-0000b Table 7-80. ATQ_CTRL9 Register Field Descriptions Bit Field Type Default Description 7-4 RSVD R/W 0000b Reserved. 3-0 KD[3:0] R/W 0000b Differential constant for tuning the auto torque PD control loop. 7.5.5.10 ATQ_CTRL10 (address = 0x28) [Default = 08h] ATQ_CTRL10 is shown in Figure 7-97 and described in Table 7-81. Read/Write Return to the Register Maps Table Figure 7-97. ATQ_CTRL10 Register 7 6 5 4 3 2 1 0 ATQ_EN LRN_START ATQ_FRZ[2:0] ATQ_AVG[2:0] R/W-0b R/W-0b R/W-001b R/W-000b Table 7-81. ATQ_CTRL10 Register Field Descriptions Bit Field Type Default Description 7 ATQ_EN R/W 0b 0 = auto torque is disabled 1 = auto torque is enabled 6 LRN_START R/W 0b Writing 1b to this bit enables the auto torque learning process. After learning is completed, the bit automatically goes to 0b. 5-3 ATQ_FRZ[2:0] R/W 001b Delay in electrical half-cycles after which current is changed in response to the PD loop. A small value increases the current quickly to meet peak load demand. This parameter has a range of 1 to 7. 001b - Fastest response time, but the loop can become unstable 111b - Slowest response, but the loop will be stable DRV8461 SLOSE98 – DECEMBER 2022 www.ti.com 92 Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated Product Folder Links: DRV8461 |
