TROUBLESHOOTING
Error Codes
In most cases, the Geo Drive communicates error codes with a text message via the serial port to the host.
Some error codes are also transmitted to the Status Display. The same message is saved in the EEPROM
under an error history log (FLTHIST, ERR) so nothing is lost when power is removed. Not all errors reflect
a message back to the host. In these cases, the no-message errors communicate only to the Status Display.
The response of the Geo Drive to an error depends on the error's severity. There are two levels of
severity:
1. Warnings (simply called errors and not considered faults and do not disable operation).
2. Fatal errors (fatal faults that disable almost all drive functions, including communications).
Note:
The Geo Drive disables automatically at the occurrence of a fault.

Description
Axis faults : n stands for axis number (n=1-2)
n F 1 01 Axis n Peak Current Fault – indicates the peak current was excessive long
enough to trip the peak current fault, but there was not enough current to
cause a nF3 fault (described below). Check for overshoots in the current
loop, make sure Ixx69 is less or equal to 24676
n F 2 02 Axis n RMS Current Fault – indicates the continuous or RMS current
rating of the drive has been exceeded. Check for binding in motor, check
if the motor is properly phased.
n F 3 03 Axis n Short Circuit Fault – indicates high output current has been
detected (fast acting). Unplug the Motor lead connectors and, if the fault
persists, send the drive for RMA. Else check your motor and cable. Do not
reset until unplugging motor cable and checking out the cause for the fault
or permanent damage could result!
n F 4 -- Reserved for future use
n F 5 05 Power Stage (IGBT) Over-Temperature Fault – indicates excessive
temperature has been detected. Check ambient temperature that it does not
exceed the limits. Power off the drive and let it cool down. If the drive is
cool and the fault persists, send the drive for RMA
n E 6 06 Motor #n Over temperature Eror Code (warning), if it insists for more than
60 seconds it will trip the Over temperature Fault.
n F 6 06 Motor #n Over temperature Fault Code, amplifier disables
n F 7 - n F F - -- Reserved for future use
0 FF Axis Enabled, drive is functioning properly.
