MEASURED_CURRENT6
: measured current for light output LD7
MEASURED_CURRENT7
: measured current for light output LD8
These registers contain the measured output currents, expressed as unsigned sixteen bits integers,
with a resolution of 1 mA. Given a register value, the corresponding actual current for a light output
can be calculated as follows:
MeasuredCurrent[x] [A] = value(MEASURED_CURRENT[x]) * 0.001
These registers are updated while the outputs are activated.
14.2.45. Registers MEASURED_VOLTAGE[0:7]
The controller is capable of measuring the actual output voltages for the eight light outputs.
MEASURED_VOLTAGE0
: measured voltage for light output LD1
MEASURED_VOLTAGE1
: measured voltage for light output LD2
MEASURED_VOLTAGE2
: measured voltage for light output LD3
MEASURED_VOLTAGE3
: measured voltage for light output LD4
MEASURED_VOLTAGE4
: measured voltage for light output LD5
MEASURED_VOLTAGE5
: measured voltage for light output LD6
MEASURED_VOLTAGE6
: measured voltage for light output LD7
MEASURED_VOLTAGE7
: measured voltage for light output LD8
These registers contain the measured output voltages, expressed as unsigned sixteen bits integers,
with a resolution of 0.1 V. Given a register value, the corresponding actual voltage for a light output
can be calculated as follows:
MeasuredVoltage[x] [V] = value(MEASURED_VOLTAGE[x]) * 0.1
These registers are updated while the outputs are activated.
14.2.46. Register ERROR_WORD
This register contains several error flags in bit field [12:0]. The register may be read and these flags
then checked to evaluate the controller health. The meaning of each of the bits is as follows.
Bit 0: set if supply for the power stages is missing, reset if supply is present
Bit 1: set if excessive temperature on LD1 and LD2 output stages, reset if safe temperature
Bit 2: set if excessive temperature on LD3 and LD4 output stages, reset if safe temperature
Bit 3: set if excessive temperature on LD5 and LD6 output stages, reset if safe temperature
Bit 4: set if excessive temperature on LD7 and LD8 output stages, reset if safe temperature
Bit 5: set if LD1 output stage has been disabled, reset if LD1 output stage is active
Bit 6: set if LD2 output stage has been disabled, reset if LD2 output stage is active
Bit 7: set if LD3 output stage has been disabled, reset if LD3 output stage is active
Bit 8: set if LD4 output stage has been disabled, reset if LD4 output stage is active
Bit 9: set if LD5 output stage has been disabled, reset if LD5 output stage is active
