Diagnostics and Troubleshooting

RMS Shunt Power

This fault is generated when RMS shunt power dissipation is greater than the design rating of the internal shunt.

Overspeed

This fault occurs when the actual motor speed exceeds the Overspeed Velocity Limit parameter. This parameter can be

accessed with PowerTools Pro software.

Max Following Error

This fault is generated when the following error exceeds the following error limit (default following error limit is 0.2 revs).

With PowerTools Pro you can change the Following Error Limit value on disable in the Position view.

Travel Limit +/-

This fault is caused when either the + or - Travel Limit input function is active.

All "On"

This is a normal condition during power up of the drive. It will last for less than 1 second. If this display persists, call Control

Techniques for service advice.

FM-3 or FM-4 Fault

A 3 or 4 will be displayed on the diagnostic display when the FM-3 or FM-4 module experiences one of the following faults.

DvTrjFlt

This fault occurs when the drive has received trajectory data from the FM module that indicates a problem or drive following

error is extremely large. 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 module.

No Prog

This fault will be displayed on initial power-up indicating that no configuration has been downloaded to the FM module. To

clear the fault, download a valid configuration to the FM module.

DrvSyn

This fault occurs when the drive loses timing with the attached FM module. This issue is generally caused by either a

trajectory update rate that is too low (800 or 1200usec), or a processor heavy program causes the program functions to overrun

the trajectory update interrupt.

Prog Flt

This fault indicates a FM module 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.

Program Invalid

The user program in flash memory will not run. Download the user program again using PowerTools Pro. A common cause

of this problem could be an interrupted configuration download, such as a cable being disconnected during the download.

DeviceNet or Profibus Fault

This fault indicates a failure in the DeviceNet or Profibus network. This fault could be caused by a major unrecoverable,

minor unrecoverable, or major recoverable. Major faults disable the bridge; minor faults do not disable the bridge and will

clear themselves after a timed period. The particular error will be displayed on the FM-3/4 module keypad display, examples

shown below.
