2.4 Functional features
- Speed control (three versions available: sensored, sense coil and sensorless as
explained in the introduction section).
- Optimum behavior on a slope due to the speed feedback: the motor speed
follows the accelerator, starting a regenerative braking if the speed exceeds the
setpoint.
- Electrical stop on a ramp (the machine is electrically hold on a slope) for a
programmable time.
- Stable speed in every position of the accelerator.
- Regenerative release braking based on deceleration ramps: regenerative
braking when the accelerator pedal is partially or fully released.
- Direction inversion with regenerative braking based upon deceleration ramp.
- Regenerative braking and direction inversion without contactors: only the main
contactor is present.
- Release-braking profile modulated by an analog input, as to obtain a
proportional-brake feature.
- Increased resolution of the speed control at low speed.
- Voltage boost at the start and with overload to obtain more torque (with current
control).
- Integrated driver for an electromechanical brake.
- Hydraulic-steering function:
a) Traction inverter:
- The traction inverter sends a "hydraulic-steering function" request to the
pump inverter on the CAN bus line.
- If the pump inverter is not present (for ex: tractor application), the
traction inverter can manage a "hydraulic-steering function" by driving a
hydro contactor which drives an hydraulic-steering motor.
b) Pump inverter:
- The pump inverter manages a "hydraulic-steering function": it drives the
pump motor at the programmed speed for the programmed time.
- High efficiency of motor and battery due to high frequency commutations.
- Double microcontroller for safety functions.
- Self-diagnosis, the faults can be monitored through the Console or through Zapi
MDI/Display.
- Modification of parameters through the programming console.
- Internal hour-meter that can be viewed from the console.
- Memory of the last five alarms with relative hour-meter and temperature
displayed on the console.
- Test function within the Console for checking the inverter parameters.
