AFNZPxxx– DUALACE2 NEW GENERATION – User Manual Page 61/169
6 FEATURES
6.1 Operational features
- Speed control or Torque control available
- 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 held in place) for a programmable time (see also paragraph
8.2.4).
- Regenerative release braking based upon deceleration ramps.
- Direction inversion with regenerative braking based upon deceleration ramps.
- Optimized speed control and reference sensitivity at low speeds.
- Hydraulic steering function:
 When DUALACE2 New Gen works as dual traction inverter:
The traction inverter sends a "hydraulic steering function" request to
the pump inverter on the CAN bus line.
 When DUALACE2 New Gen works as combi inverter:
The pump inverter manages a 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.
- Double microcontroller for safety functions.
- Self-diagnoses with faults displayed by means of Zapi tools (Smart console,
PC CAN Console) or Zapi MDI/Display.
- Inverter settings managed by means of Zapi tools (Smart console, PC CAN
Console).
- Log of alarms history.
- TESTER function for monitoring the main readouts
6.2 Dual traction motor
In the case of a dual-traction setup, there is the additional processing of the
associated steering signal (from a potentiometer or switches) in order to generate
separate torque demands for the left and right motors of the vehicle. This allows
the two motors to be operated at different speeds, which greatly assists in turning
the vehicle and prevents wheel scrub. After the torque demands have been
generated, the operation of each motor control system is as described in the case
of a single traction motor.
6.3 Pump motor
Pump motor control is similar to traction motor control, although motion is
requested using a different combination of switches.
