AKD F131 Emulated Encoder Line Break
The AKD will generate a F131 fault when it detects that a channel, and it's complement, have a difference in voltage absolute magnitude greater than 0.2V / 200mV.
EXAMPLES: If "A" channel has a magnitude of 4.2V and "A not" is -4.1, the absolute difference in voltage is 0.1V. No fault is generated. If "A" channel is 4.3V and "A not" is -4.1V, a F131 fault will be generated.
