34311, Drive inverter saturated warning
Description
The drive unit for joint arg has reached maximum output voltage.
The joint is connected to drive module arg with 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 is not properly connected to the drive unit. The motor
data in the configuration is not correct. The DC link voltage is
too low. Short circuit between motor phases or ground.
Recommended actions
Check motor cables and connectors. Check configuration of
motor parameters. Check for other hardware event log
messages. Check incoming mains voltage to the rectifier unit,
adjust the mains tolerance min value. Check the motor cable
and motor by measuring their resistance respectively.
Disconnect before measuring.
34312, Missing drive unit
Description
For joint arg, the system cannot find configured drive unit. The
joint is configured for drive module arg, in the drive unit at unit
position arg.
Consequences
The system goes to system failure state.
Probable causes
A joint is configured but drive unit is not found.
Recommended actions
Verify that the drive module contains the drive unit for the
configured joint. Verify that the configuration for the drive unit
position is correct. Verify that the cables between drive units
are correctly inserted in the correct connector position. If the
cable is correctly connected, then it may be damaged and
should be replaced. Check the event log for power supply unit
error messages. Check the cabling between the power supply
unit and the drive unit. Check the 24V output from the power
supply unit.
34313, Wrong type of drive unit
Description
In drive module arg, the hardware identity for drive unit at unit
position arg is different from the one specified in the
Continues on next page

configuration. Installed drive unit hardware identity is arg, and
the configured identity is arg.
Consequences
No operation will be possible until the fault is corrected. The
system goes to system failure state.
Probable causes
The drive unit type does not match the one specified in the
installation key.
Recommended actions
Verify that the drive unit position is correct, i.e., the Ethernet
cables are correctly connected. Verify that the drive module
key match the installed hardware. Replace the drive unit with
the one specified in the drive module key.
34314, Missing drive unit node
Description
For joint arg, the drive unit does not support the node number
configured. The joint is configured for drive module arg, in the
drive unit at unit position arg with node arg.
Consequences
The system goes to system failure state.
Probable causes
The configured drive unit node is not supported for the
configured type of drive unit.
Recommended actions
Check the drive unit node number in the configuration.
34316, Motor current error
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
The system goes to Motors Off state.
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
