4 Protective Features
DSP Fault – Set when the internal DSP checksum fails following reset
NVM Fault – Set when NVM checksum fails following reset. Parameter defaults set.
Ex5V – 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 maximum allowed (75 Vdc)
Hall Error – Set when hall sequence is invalid (0 or 7 value is read on hall inputs)
Fatal Error – Set if the DSP encounters an unidentified problem.
Amplifier Over Temp – Set when amplifier heat sink temperature exceeds 70 C.
Motor Over Temp – Set when motor temperature input is open
Overcurrent – Set when amplifier detects an overcurrent condition
Bus Under Voltage – Set when Bus voltage is less than the minimum allowed (10 Vdc)
Bias error – Set when Bias voltage input +/-15 is outside allowable range
2.5V Reference error – Set when internal 2.5V supply is out of range.
