TT30: AC current
– Torque Mismatch
Description
The Troubleshooting Tree 30 indicates an error where
the
level of torque to the motor doesn’t match the
amount of power delivered by the AC current.
The Connections between the motor and the MCU,
and the damaged phase cables or motor sensor
cables defectives may cause the SysFile ID.
The incorrect connection configuration (Standard or
Reverse) of the phase cables may cause the issue.
The loss of sensor connector integrity may cause the
SysFile ID.
All the phase cables and their connection on the MCU
and the motor are needed to be fully functional and
complying to the installation manual.
TM4 ODIN diagnostic tool allows to visualize the
motor resolver angle waveform: see next page.
The MCU itself may be defective.
Note: Refer to the TM4 Product installation guide and
operation and maintenance manual for more details
on the phase cables configurations and parameter
setting.
Note : Refer to the motor installation guide for more
details on installation and deinstallation procedure
including safety warning considerations.
Note : Refer to the Dana TM4 product(s) MCU
installation guide(s) for more details on installation
and deinstallation procedure including safety warning
considerations.
Note: If the MCU goes in failure, it will capture a
BlackBox upon the high voltage battery reached the
high limit error. The BlackBox can then be consulted
via ODIN tool to see if the angle waveform (saw tooth)
is straight on each rise and fall edges.
To correctly diagnose the faulty system, connect the
Diagnostic Tool (see «Diagnostics» section for test
equipment and descriptions) and follow the
troubleshooting tree procedure below.
See “Safety Warnings” and “Troubleshooting Tips”
sections for general guidelines on system diagnostics.

The reference torque is
not matching with the
estimated torque (most of
the time lower than
reference).
1.
Phase cable lugs not properly assembled
on inverter or motor.
2.
Wrong phase cables order.
3.
Motor resolver signal incoherence
(intermittence signal, distorted signal).
4.
Defective MCU.
