Description
This parameter enables or disables the functionality that
continues to give torque even if the traction (or lift) request
has been released.
ON = When the operator releases the traction request,
the inverter keeps running the truck, as to oppose the
friction that tends to stop it. Similarly, in pump
applications, when the operator releases the lift
request, the inverter keeps running the pump avoiding
the unwanted descent of the forks.
OFF = When the operator releases the traction (or lift)
request, the inverter does not power anymore the
motor. This setting is useful especially for traction
application. When the truck is travelling over a ramp
and the driver wants to stop it by gravity, the motor
must not be powered anymore, until the truck stops.
This parameter enables or disables the control of the
deceleration rate of the truck when the accelerator is
released.
ON = When the accelerator is released, the inverter
controls the deceleration rate of the truck through the
application of a linearly decreasing torque curve. This
is useful when the operator releases the accelerator
while the truck is going uphill. If the rise is steep, the
truck may stop fast and may also go backwards in
short time, possibly leading to a dangerous situation.
OFF = When the accelerator is released, the inverter
does not control the deceleration rate of the truck,
instead it stops driving the motor.
This parameter defines the quick-inversion functionality.
NONE = The quick-inversion function is not managed.
BRAKE = Upon a quick-inversion request, the motor is
braked.
TIMED = The quick-inversion function is timed: upon a
QI request the controller drives the motor in the
opposite direction for a fixed time (1.5 seconds by
default).
BELLY = The quick-inversion function is managed but
not timed: upon a QI request the controller drives the
motor in the opposite direction until the request is
released.
This parameter defines the kind of brake pedal adopted.
ON = Brake pedal outputs an analog signal, braking is
linear.
OFF = Brake pedal outputs a digital signal, braking is
on/off.
This parameter defines the function associated with input
A19
(A13).
ON = Handbrake.
OFF = Speed reduction.

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.
