The six-step encoder sensor signals are connected to the SH1, SH2 and SH3 inputs
(chapter 4.2.6) and the sensor is supplied using sensor supply (see chapters 4.4.10).
Care must be taken to ensure that the six-step hall device matches the motor
controller sensor supply voltage
Sinusoidal Motor Speed Sensor Input
The sinusoidal sensor for synchronous motors provides position, speed and direction
feedback for the motor controller. The sinusoidal analog sensor produces a single-ended
two-phase sinusoidal wave output (see Figure 19).
Connect the feedback sensor according to chapter 4.2.5.
Dynamic offset and gain adjustments (individual for each channel) are done in software
to compensate for minor changes in sensor characteristics.
It is suggested to share with Zapi technicians the specifications of the
adopted encoder in order to be sure about its full compatibility with the
Zapi controller
The number of pulses/rev can be properly set using the dedicated
parameters (see paragraph 8.2.7).

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.
