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:
- 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.
- 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.
