39435, Cannot find additional axis drive unit
Description
The system cannot detect an additional axis drive for joint arg
in drive module arg.
Consequences
System goes to SYS_FAIL.
Probable causes
This can be due to: Having an additional axis configured but
not having a drive unit in the drive module. Having an external
drive unit but not connecting the cable to the X arg connector
position on the main drive unit. Damaged cable between the
additional axis drive and the main drive unit.
Recommended actions
Check the drive module contains enough additional axis drives.
Check that the configuration key does not define more external
drive units then are connected in the drive module Check the
cable between the additional axis drive unit and to the main
drive unit is correctly inserted in the right connector position.
If the cable exists and is correctly inserted, then it may be
damaged and should be replaced.
39440, Open circuit in bleeder resistor circuit
Description
The bleeder resistor connected to the rectifier on drive link arg,
drive module arg, is an open circuit.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
This may be caused by a faulty bleeder resistor cable or bleeder
resistor.
Recommended actions
Make sure the bleeder resistor cable is correctly connected to
the rectifier unit. Make sure the cable and resistor is working
correctly by measuring their resistance respectively. Disconnect
before measuring. Replace any faulty component.
39441, Short circuit in bleeder resistor circuit
Description
The bleeder resistor connected to the rectifier on drive link arg,
drive module arg, is a short circuit.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.

Probable causes
This may be caused by a faulty bleeder resistor cable or bleeder
resistor.
Recommended actions
Make sure the bleeder resistor cable is correctly connected to
the rectifier unit. Make sure the cable and resistor is working
correctly by measuring their resistance respectively. Disconnect
before measuring. Replace any faulty component.
39442, Bleeder Resistance Too Low
Description
The bleeder resistance is too low 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 bleeders may have the wrong resistance value or one of
the bleeders may have failed, causing a short circuit.
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. How to check the configuration
file is detailed in the Trouble Shooting Manual.
39443, Bleeder Resistor Overload Warning
Description
The power consumed by the bleeder resistors is approaching
overload 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.
Recommended actions
Rewrite the user program to reduce the amount of hard braking.
39444, Bleeder resistor overload error
Description
The bleeder resistors have been overloaded for the rectifier on
drive communication link arg, drive module arg.
