C50A20 5V, 3V3 or ADC error (5V too
high)
C50A21 5V, 3V3 or ADC error (5V too
low)
C50A22 Robot current sensor reading
too high
C50A23 Robot current sensor reading
too low
C50A24 48V not present (Check
internal connection)
This error can have several root causes and you have to measure the voltage some places.
There are 3 different components that could be the root cause and you have to measure the
voltage to determine which one of them that is the faulty one.
- 48 V power supply
- Current distributor
- Safety Control Board.
