9.15 Motor thermal protection
The controller performs a thermal protection of the driven motor by monitoring its
temperature and applying a linear cutback to the maximum current when it
becomes excessive.
Thermal protection can be tuned setting parameters MAX. MOTOR TEMP.,
TEMP.MOT. STOP ADJUSTMENTS list.
A linear reduction is performed for temperatures between MAX. MOTOR TEMP.
and TEMP. MOT. STOP . It acts scaling down the torque profile (see paragraph
9.15) by a percentage from 100% to 50%.
When motor temperature reaches TEMP. MOT. STOP, current cutback is fixed to
50%.
Cutback is valid only during motoring, instead during braking the 100% of the
maximum current is always available regardless the motor temperature.
If the signal from the motor thermal sensor is out of range (for example due to a
problem related to the wiring), a cutback equal to 50% is applied.

Questions and answers
Como comprobar el funcionamiento del controlador dualac2 sin display
You can check the operation of the Zapi DUALACE2 NEW GENERATION controller without a display using the following methods:
1. Zapi Smart Console – Connect the Zapi Smart Console to the CAN bus to access diagnostics and parameter settings.
2. PC CAN Console – Use the PC CAN Console software to monitor and adjust controller settings.
3. Self-Diagnosis Feature – The controller performs self-diagnosis, and faults can be displayed using Zapi tools.
4. Alarm History Log – Check the log of alarms to review past faults and system behavior.
5. TESTER Function – Use the TESTER function to monitor key operational readouts.
These methods allow you to diagnose and verify the controller’s operation without an external display.

A brumby electrical truck that has a zapi inv.dace2, records the failure 244 "Warning Slave It depends on the supervisor uc", and the alarm 248 "Mc is Opened, eb is applied". On the other hand, the LED does not turn on, but in the manual I did not find the LED code. I would like more certainty about whether the failure is from the controller and the LED code for this Zapi model.
Failure 244 "Warning Slave" depends on the supervisor microcontroller (µC). No specific effect or troubleshooting steps are provided in the available context.
Alarm 248 "MC is Opened, EB is Applied" indicates that the main contactor (MC) is open, and the electric brake (EB) is applied. This typically occurs during start-up, standby, or other system states.
The LED code for this model is not explicitly provided in the available context.
