34267, Too many rectifiers connected
Description
In drive module arg the system has detected more rectifiers
than the system can handle. The limit was reached when drive
unit at unit position arg was detected.
Consequences
No operation will be possible until the fault is corrected. The
system goes to system failure state.
Probable causes
Too many drive unit that are equipped with rectifiers are
connected.
Recommended actions
Verify that the proper drive units' types are connected to the
drive unit communication link. Disconnect unused drive unit(s).
34268, Rectifier charging error
Description
In drive module arg, the dc-link in the rectifier unit at drive unit
position arg has too low voltage.
Consequences
No operation will be possible until the fault is corrected. The
system goes to Motors Off state.
Probable causes
Low AC-voltage level to rectifier input. This may be caused by
a faulty rectifier bleeder. The bleeder resistor or its wiring is
faulty. A short circuit is present on the dc-link.
Recommended actions
Restart the controller and try again. Check incoming mains
voltage. If new installed system with mains transformer - check
transformer voltage selection. Check bleeder resistor and its
wiring. If the problem remains then replace the unit.
34300, Unknown drive unit type
Description
In drive module arg, the drive unit at unit position arg has an
unknown hardware identity arg.
Consequences
No operation will be possible until the fault is corrected. The
system goes to system failure state.
Probable causes
The drive unit is either unsupported or faulty.

Recommended actions
Verify that the drive unit is supported by the RobotWare version.
Upgrade RobotWare if needed. Replace drive unit.
34303, Motor current warning
Description
For joint arg, the current controller detected a too large torque
current deviation for the motor. The joint is connected to drive
module arg in the drive unit at unit position arg and node arg.
Consequences
Operation will be possible but system is close to a stopping
error.
Probable causes
The motor data in the configuration files may be wrong. The
motor cables are not correctly connected or damaged. Short
circuit in motor cable between phase to phase or phase to
ground. The DC link voltage may be too low. The incoming
mains voltage is not within specification.
Recommended actions
Verify that the motor data in the configuration file is correct for
this joint. How to check the configuration file is detailed in the
Trouble Shooting Manual. Verify that the motor cables are not
damaged or badly connected. Verify that the motor cables has
no short circuits internally or to ground. Verify that no DC link
errors are present in the event log. Verify that the incoming
mains voltage is within the specification.
34304, Motor current warning
Description
For joint arg, the current controller detected a too large current
deviation for the motor. The joint is connected to drive module
arg in the drive unit at unit position arg and node arg.
Consequences
Operation will be possible but system is close to a stopping
error.
Probable causes
The motor data in the configuration files may be wrong. The
motor cables are not correctly connected or damaged. Short
circuit in motor cable between phase to phase or phase to
ground. The DC link voltage may be too low. The incoming
mains voltage is not within specification.
Recommended actions
Verify that the motor data in the configuration file is correct for
this joint. How to check the configuration file is detailed in the
Trouble Shooting Manual. Verify that the motor cables are not
