Operational Features - Zapi ACE2 User Manual

5 OPERATIONAL FEATURES

- Speed control (three versions available: sensored, sense coil and sensorless
as explained in the introduction section) .
- Optimum behaviour on a slope due to the speed feedback:
- the motor speed follows the accelerator, starting a regenerative braking if the
speed overtakes the speed set-point.
- the system can perform an electrical stop on a ramp (the machine is
electrically hold on a slope) for a programmable time (see also chapter 8.4).
- Stable speed in every position of the accelerator.
- Regenerative release braking based upon deceleration ramps.
- Regenerative braking when the accelerator pedal is partially released
(deceleration).
- Direction inversion with regenerative braking based upon deceleration ramp.
- Regenerative braking and direction inversion without contactors: only the
main contactor is present.
- The release braking ramp can be modulated by an analog input, so that a
proportional brake feature is obtained.
- Optimum sensitivity at low speeds.
- Voltage boost at the start and with overload to obtain more torque (with
current control).
- The inverter can drive an electromechanical brake.
- Hydraulic steering function:
-
-
- High efficiency of motor and battery due to high frequency commutations.
- Self diagnosis, the faults can be displayed through the console or Zapi's
MDI/Display.
- Modification of parameters through the programming console.
- Internal hour-meter with values that can be displayed on the console.
- Memory of the last five alarms with relative hour-meter and temperature
displayed on the console.
- Test function within console for checking main parameters.

traction inverter
- the traction inverter sends a "hydraulic steering function" request to
the pump inverter on the can-bus line (see also OPTIONS chapter
8.4).
- moreover, if the pump inverter is not present (for ex: tractor
application), the traction inverter can manage an "hydraulic steering
function" by driving a hydro contactor which drive an hydraulic
steering motor (output A18), see also OPTIONS chapter.
pump inverter
the pump inverter manage an "hydraulic steering function". That is, it
drives the pump motor at the programmed speed for the programmed
time.
