Traj Fault

This fault occurs when the drive has received trajectory data from the FM-3 that indicates a problem. Check the user units, velocities, accels and decels for correct values.

ISR Overrun

This fault is generated when a module flash memory problem occurs. To correct, replace the FM-3.

OutofSync

This fault is generated when the system is out of sync. To correct it, press the reset button and check the configuration.

ProgramFault

This fault indicates an FM-3 user program fault. For example the program is attempting to divide by zero, or overflows and math errors caused by numbers that are too large, or non- existing parameters.

ProgramInvalid

The user program in flash memory will not run. Download the User Program again using PowerTools FM-3. A common cause of this problem could be an interrupted configuration download, such as a cable being disconnected during a download.
