39405, Maximum PWM Reached in Torque
Controller
Description
The torque-current control loop has been saturated for joint
arg, connected to drive module arg.
Consequences
Probable causes
The mains voltage may be too low or the motor windings or
motor cables may be broken.
Recommended actions
Check that no DC bus errors are present in the event log. Check
that the incoming mains voltage is within specified limits. Check
the motor cables and motor windings for open circuits.
39406, Field Loop overcurrent
Description
The field-current control loop has produced too high current
for joint arg, connected to drive module arg.
Consequences
Probable causes
The motor data in the configuration files may be wrong.
Recommended actions
Check that no DC bus errors are present in the event log. Check
that the incoming mains is within specified limits. Check the
motor cables and motor windings.
39407, Drive Unit has the wrong type code
Description
The type code in drive unit for joint arg in drive module arg is
different from the one specified in the configuration file. Installed
drive unit type is arg, and the configured type is arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The configuration file may contain incorrect values, the
configuration key may be incorrect or the hardware may be of
the wrong type. If the drive unit was recently replaced, a drive
unit with the wrong type code may have been fitted or the key
was not replaced with one for the correct hardware/software
combination.

3HAC020738-001 Revision: AA
Recommended actions
Make sure the values in the configuration file match the installed
hardware. Make sure the configuration key match the installed
hardware/software combination. How to check the configuration
file is detailed in the Trouble Shooting Manual. If the drive unit
was recently replaced, make sure a unit of the correct type code
is used.
39408, Rectifier Unit has the wrong type code
Description
The type code for rectifier unit arg in drive module arg is
different from the one specified in the configuration file. Installed
rectifier unit type is arg, and the configured type is arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to system failure state.
Probable causes
The configuration file may contain incorrect values, the
configuration key may be incorrect or the hardware may be of
the wrong type. If the rectifier unit was recently replaced, a
rectifier unit with the wrong type code may have been fitted or
the key was not replaced with one for the correct
hardware/software combination.
Recommended actions
Make sure the values in the configuration file match the installed
hardware. Make sure the configuration key match the installed
hardware/software combination. How to check the configuration
file is detailed in the Trouble Shooting Manual. If the rectifier
unit was recently replaced, make sure a unit of the correct type
code is used.
39409, Capacitor Unit has the wrong type code
Description
The type code for capacitor unit arg in drive module arg is
different from the one specified in the configuration file. Installed
capacitor unit type is arg, and the configured type is arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The configuration file may contain incorrect values, the
configuration key may be incorrect or the hardware may be of
the wrong type. If the capacitor unit was recently replaced, a
capacitor unit with the wrong type code may have been fitted
