Hi
I have 2 qeustion to the data sheet
Table 7-67. BUS_CURRENT Register Field Descriptions
32-bit value indicating DC bus current; I_dcBus (A) =
(BUS_CURRENT / 227) * 1.25
1: is the values signed?
07086 TI_I2C_bus_read reg_: Register 0478 -> 03FC8000
07091 TI_I2C_bus_read reg_: Register 0210 -> 00200009
07096 TI_I2C_bus_read reg_: Register 0752 -> 023D6B2F
07101 TI_I2C_bus_read reg_: Register 0410 -> 000BB7BF
07106 TI F_RPM: 10020 V:29 I:0.01 SM:09 MOTOR_CLOSED_LOOP_ALIGNED
07106 current: 0x00000015(21)
07106 volt: 0x0000001D(29)
07308 TI_I2C_bus_read reg_: Register 0478 -> 03FC8000
07313 TI_I2C_bus_read reg_: Register 0210 -> 00200009
07318 TI_I2C_bus_read reg_: Register 0752 -> 032F6416
07323 TI_I2C_bus_read reg_: Register 0410 -> FFFF80F7
07328 TI F_RPM: 14280 V:29 I:40.00 SM:09 MOTOR_CLOSED_LOOP_ALIGNED
07328 current: 0x0000D4BF(54463)
07328 volt: 0x0000001D(29)
2. Also the Values does not macht my meassured Current at my Power Supply
e,g, Register -> 0.3A
Show on Powersuppy 1.5A
A turbine is running at 28kRPM.
This also happens with the EVAL board!
Any idear?
