0x517 - Current loop status

Address	Name	Data Type	Access	Cyclic access	NVM	Value range	Default value	Units
0x517	Current loop status	UINT32	RO	Yes	No	Data type	-	-

This register shows the status of the current control loops.

The meaning of each bit in this parameter is described next.

Block	Current D/B loop status
Bits	31	30...28	27	26	25	24	23...20	19	18	17	16
Meaning	Loop enabled	Reserved	Derating limiting latching	I2T limiting latching	Upper saturator active latching	Lower saturator active latching	Reserved	Derating limiting	I2T limiting	Upper saturator active	Lower saturator active

Block	Current Q/A loop status
Bits	15	14...12	11	10	9	8	7...4	3	2	1	0
Meaning	Loop enabled	Reserved	Derating limiting latching	I2T limiting latching	Upper saturator active latching	Lower saturator active latching	Reserved	Derating limiting	I2T limiting	Upper saturator active	Lower saturator active

Note

The latching bits of the control loops status get reset whenever the power stage transitions to "operation enabled" state or whenever a current loop PID parameter is changed.

Warning

When the commutation modulation type parameter is set to Brushless DC or Brushed DC, only the current quadrature path is used. In this case, the Current D/B loop status bit field must be ignored.
