A.2 Diagnostic Flags
The diagnostic register holds a 16 bit value that represents 16 individual flags, when set (value ‘1’), this indicates the
following conditions have occurred or are still present, the highest 7 bits are latching and will be present in t he register
even if the initial cause for the flag being set is removed. If these flags are set, a reset needs to be performed to clear
the fault.
A.2.1 Fault in NV Memory
This is a severe fault and is usually seen when the firmware is upgraded with a program that uses a different
EEPROM/Non-volatile memory map. If this is not the case then the probable c ause is a fault in the memory hardware.
A.2.2 M otor Assembly Stall
Thevalveplugwasunabletomovetothecommandedposition.Thedrivehasattemptedtomovethemotorby
applying a non-zero PWM signal, and the speed has not been detected as greater than 0 with a 400ms period. This
fault latches and needs to be reset.
A.2.3 Speed Measurement Fault
The controller detected pulses that correspond to the motor going much faster than the speed the speed
measurement system is designed for — the integrity of the measurement cannot be relied upon. This fault latches and
needs to be reset.
A.2.4 System or Watchdog Fault
The software system has been reset and this flag is set at power up if the case of the reset was the onboard watchdog
either timing out OR being forced by program function call. This flag is used as an indication that this type of reset has
occurred.
