Watchdog Timer Trip
On a Geo Brick Drive, the watchdog timer trigger illuminates the red WD LED and interrupts
communication. It occurs if any of the following is true:
communication. It occurs if any of the following is true:
PMAC CPU over-clocked
In this mode, the CPU signals that is has been overloaded with computation and cannot
In this mode, the CPU signals that is has been overloaded with computation and cannot
accomplish tasks in a timely manner. i.e. bad programming such as an infinite loop, or too much
computation (Kinematics) requiring faster CPU option.
Wrong clock settings
In this mode, the user has downloaded or written bad values to clock setting parameters.
In this mode, the user has downloaded or written bad values to clock setting parameters.
Hardware +5V failure (internal)
In this mode, the internal 5V logic circuitry has failed. Check 5V Led Status.

Downloading wrong configuration file (I4900)
In this mode, the user has reloaded a configuration file uploaded from a 4-axis unit (Servo IC 1
In this mode, the user has reloaded a configuration file uploaded from a 4-axis unit (Servo IC 1
parameters set to zero) into an 8-axis unit, thus writing zero to the second Servo IC clock
parameters. Commenting out variables I7100…7106 (or forcing then to hold the same values as
I7000…I7106) eliminates the watchdog problem.
