2.6 OPERATIONAL FEATURES
- Speed control.
- Optimum behavior an 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 4.4)
- 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:
1) traction inverter
- the traction inverter sends a "hydraulic steering function" request to the pump inverter
on the can-bus line (see also OPTION chapter 4.4)
- 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 a hydraulic steering motor (output A7 (Saab), B9 (Minifit), see also OPTION chap-
ter)
2) 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 with indication of the fault shown by a flashing led.
- 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.
