46 1 EEPROM 1. New software loaded into EEPROM Error in EEPROM CRC calculation. Cycle KSI. Shutdown. 1 = Stop.
CRC Fault memory.
2. Try using function “Restore to Factory Defaults” to clear fault.
3. Controller defective. 47 1
Sin/Cos 1. Sin/Cos Sensor defective. The Analog 1 and Analog 3 inputs do not Cycle KSI. Hold then 1 = Stop. Command 2. Sin/Cos Sensor parameters match the expected sine and cosine signals. Shutdown. Sensor are mis-tuned. They must be within the parameter Fault
Volts of the ideal waveform as defined by
the Gain and Offset parameters. 47 2 Sawtooth
1. Sawtooth Sensor defective. The Analog 1 and Analog 3 inputs do not Cycle KSI. Hold then 1 = Stop.
Command 2. Sawtooth Sensor parameters match the expected sawtooth waveform. Shutdown. Sensor are mis-tuned. They must be within the parameter
