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. Change the mains
tolerance min so that it reflects the actual mains voltage.
34317, Motor current error
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
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
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. Change the mains
tolerance min so that it reflects the actual mains voltage.
34318, Drive inverter saturated error
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
The system goes to Motors Off state.
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.
Operating manual - Troubleshooting IRC5
3HAC020738-001 Revision: AA
Check the motor cable and motor by measuring their resistance
respectively. Disconnect before measuring.
34319, Drive unit critical error
Description
The drive unit for joint arg gives an unspecified error, but is
likely due to over temperature or short circuit. The joint is
connected to drive module arg with the drive unit at unit position
arg and node arg.
Consequences
No operation will be possible until the fault is corrected. The
system goes to Motors Off state with zero torque.
Probable causes
The cooling fans may be faulty or the air flow may be obstructed.
The cooling fins are covered by dust reducing the cooling effect.
The ambient temperature may be too high. The joint may be
running with a too high torque for extended periods of time.
Short circuit in cables or connectors between the phases or to
ground. Short circuit in motor between the phases or to ground.
Recommended actions
Verify that the fans are running and that the air flow is not
obstructed. Clean the cooling fins. Verify that the ambient
temperature does not exceed the cabinet's temperature rating.
If possible, rewrite the user program to reduce the amount of
hard acceleration and hard deceleration. Reduce the static
torque due to gravity or external forces. Check/replace cables
and connectors. Check/replace motor.
34320, Too many drive nodes connected
Description
In drive module arg the system has detected more drive nodes
than the system can handle. The error occurred 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 units is connected to the drive unit
communication link. The connected drive units can be of wrong
types, and may be equipped with too many drive nodes.
Recommended actions
Verify that the proper drive unit types are connected to the drive
unit communication link. Disconnect unused drive unit(s).
