TT05: Hardware Failure Detected
Description
The Troubleshooting Tree 05 indicates that there is a
hardware error that may cause the system to go to
defective mode, whereby it will cease operation.
Components that may be the cause of the error are:
1. Motor Temperature sensors,
2. Resolver Chip,
3. Motor position sensor.
The resistance measurements of the resistance
values of the related
“Machine Internal Resistances”
may not be aligned as per Machine internal resistance
measurement table. The motor should be considered
defective.
The loss of integrity of the motor sensor connector on
the MCU leads to consider defective MCU.
Note : If the motor is a TM4 machine, then the
expected values of the measurements should be
between 10 Ohm and 5 kOhm. If the motor is not a
TM4 machine, then the measurements may be
different and refer to your machine specification.
Note : Refer to the TM4 motor installation guide for
more details on installation and deinstallation
procedure including safety warning considerations.
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.
