Description
This parameter defines the type of the adopted speed
sensor for motor 2. Factory adjusted.
0 = Incremental encoder.
1 = Sin/cos sensor.
2 = Incremental encoder + sin/cos sensor.
3 = Incremental encoder + sin/cos sensor + index.
4 = PWM absolute sensor + incremental encoder +
index.
5 = Resolver.
6 = Hall effect sensor (six-step).
It defines how the signal sequence coming from the
encoder channels is expected by controller 2
OPTION#1 = Channel A anticipates channel B.
OPTION#2 = Channel B anticipates channel A.
It permits to change the sequence in which the motor 2
phases are powered. Factory adjusted.
OPTION#1 = U-V-W corresponds to forward direction.
OPTION#2 = V-U-W corresponds to forward direction.
This parameter defines the number of encoder pulses per
revolution (motor 2). It must be set equal to ENCODER
PULSES 2; otherwise the controller raises an alarm.
The available options are:
25
32
124
128
NOTE: with standard HW, the capability to use encoders
with high number of pulses could be limited depending on
the speed. Ask to Zapi technician before to operate on this
parameter

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.
