8.4 L.E.D. Error Codes and Meaning
The following table lists the L.E.D. error codes and their meaning. If multiple errors are present, the
display will cycle through all the error codes, displaying each for ½ second.
Amp ok, motor current enabled. This is the “normal” display when enabled.
DSP Fault – Set when the internal DSP checksum fails following reset
NVM Fault – Set when NVM checksum fails following reset. Parameter
defaults are set.
Hall 5vdc – Set when on board +5v supply for Halls is out of range
Autobalance Fault – Set when autobalance can’t balance amplifier outputs.
ABS Overcurrent – Set when instantaneous overcurrent condition is detected
SOA – Set when Safe Operating Area protection detects an over power
condition.
5 VDC Reference error – Set when in5 reference supply is out of range
Bus Over Voltage – Set when Bus voltage is greater than +/-75 Vdc.
`
(Note: Each leg (+ and -) is checked against this value.)
Amp ok, not enabled (Output is Clamped off). This is the normal display when
the amplifier is not enabled.
2.5 Vdc Reference error – Set when internal 2.5vdc supply is out of range.
