Description
The Troubleshooting Tree 34 indicates a phase
current mismatch between 3 phases systems.
The MCU may be defective and prevent one of the
motor phase current to circulate within the respective
motor phase of the motor.
The motor may be defective and could have an
internal motor phase opened that prevent current
circulation in that motor phase.
Note : regarding this type of error
If the software detects a phase current mismatch
between the 3 phases systems, it will raise this error
by stopping the system to be in operation right away
preventing another motor phase to burn internally.
To correctly diagnose the faulty system, connect the
Diagnostic Tool (see «Diagnostics» section for test
equipment and descriptions) and follow the procedure
of Troubleshooting Tree below.
See “Safety Warnings” and “Troubleshooting Tips”
sections for general guidelines on system diagnostics.
