9.2.2.6. Battery voltage management
The AMIS-30622 monitors the battery voltage by mean of one threshold and one shutdown level, as illustrated in
the state diagram below. The only condition to reset flags <UV2> and <StepLoss> is to recover a battery
voltage higher than UV1 and to receive a GetFullStatus1 command.
Normal voltage
- <UV2> = ‘0’
- <StepLoss> = ‘0’
- Motion enabled
Vbb > UV1 &
S²I frame:
GetFullStatus1
Vbb < UV2
(no motion)
Stop mode 1
- <UV2> = ‘1’
- <StepLoss> = ‘0’
- Motor shutdown
(motion disabled)
Vbb < UV2 &
motion ongoing
Stop mode 2
- <UV2> = ‘1’
- <StepLoss> = ‘1’
- HardStop
- Motor shutdown
(motion disabled)
