Continued
Recommended actions
Check the bleeder resistors to see that they are the correct
resistance value for this drive module configuration. Check that
none of the resistors have failed. If possible, rewrite the user
program to reduce the amount of hard braking.
39462, DC Link Voltage at Critical
Description
The DC link voltage is critically high for the rectifier on drive
communication link arg, drive module arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The user program may contain too much hard braking of the
manipulators, which is more likely if the system contains
additional axes. The brake resistors may also be faulty.
Recommended actions
Check the bleeder resistors to see that they are the correct
resistance value for this drive module configuration. Check that
none of the resistors have failed. Rewrite the user program to
reduce the amount of hard braking.
39463, Motor Phase Short Circuit Warning
Description
A brief short circuit was detected in the motor/motor cable for
the motor attached to joint arg in drive module arg.
Consequences
Probable causes
This may be due to dust or metal fragments contaminating the
contacts or motor windings.
Recommended actions
No action is required if the problem does not persist.
39464, Short circuit in Motor phase circuit
Description
The motor or motor cable for joint arg in drive module arg, drive
unit number arg, is a short circuit.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.

204
Probable causes
This may be caused by a faulty motor or motor cable. It may
also be caused by contamination in the contactors for the cables
or a failure of the motor windings.
Recommended actions
Make sure the motor cable is correctly connected to the drive
unit. Check the cable and motor by measuring their resistance
respectively. Disconnect before measuring. Replace any faulty
component.
39465, Motor current warning
Description
The motor current is higher than the allowed for joint arg in
drive module arg, drive unit number arg.
Consequences
Probable causes
The motor load may be too high or the motor may have stalled
(maybe due to a collision).
Recommended actions
Check that the robot has not collided with anything. If possible,
reduce the speed of the user program. If the axis is an additional
axis, check that the motor load is not too high for the drive unit.
39466, Motor Current Overload
Description
The motor current is too high for joint arg in drive module arg,
drive unit number arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The motor load may be too high or the motor may have stalled
(maybe due to a collision).
Recommended actions
Check that the robot has not collided. If possible, reduce the
speed of the user program. If the axis is an additional axis,
check that the motor load is not too high for the drive unit.
39467, Drive Unit Temperature Warning
Description
The temperature has risen above the warning level in drive unit
number arg, drive module arg, which is the lowest abnormal
level of three.
Consequences
