8.5 Parameter regulation
8.5.1 "Dualac2" - Master
The following parameters can be modified:
1) ACCELER. DELAY
It determines the acceleration ramp.
2) RELEASE BRAKING
It controls the deceleration ramp when the travel request is released.
3) INVERSION BRAKING
It controls the deceleration ramp when the direction switch is inverted during
travel.
4) PEDAL BRAKING
It determines the deceleration ramp when the travel request is released and
the brake pedal switch is closed.
5) SPEED LIMIT BRAKING
Deceleration ramp when the pedal position is changed but not completely
released.
6) BRAKE CUTBACK
It determines the deceleration ramp when the speed reduction input becomes
active and the motor slow down.
7) MAX SPEED FORWARD
It determines the maximum speed in forward direction.
8) MAX SPEED BACKWARD
It determines the maximum speed in backward direction.
9) CUTBACK SPEED 1
Typically from 10% to 100%. It determines the percentage of the max speed
applied when the cutback switch is active. When set to 100% the speed
reduction is ineffective.
10) CURVE CUTBACK
Speed reduction when the truck is doing a curve. The parameter sets the
speed setpoint when the truck driving wheels are running in opposite
direction (3 wheels truck, steering angle greater than roughly 67°); or when
the maximum steering angle is reached (4 wheels truck, the internal wheel is
stopped). In intermediate steering angles, the speed setpoint will be within a
range between the straight wheel speed and the CURVE CUTBACK SPEED.
11) FREQUENCY CREEP
Minimum speed when the forward or reverse switch is closed, but the
accelerator is on a minimum position.
12) MAXIMUM CURRENT
This changes the maximum current of the inverter.
13) BACKING SPEED
Drive Motor Speed during the Backing function (when the backing switch is
closed).
14) BACKING TIME
Operation time of the Backing Function, during which the backing switch is
closed.
15) ACC. SMOOTH
It gives a different form to the acceleration curve in the frequency range 0 Hz
to “Stop smooth” value (see the figure below).
16) INV. SMOOTH
It gives a different form to the acceleration curve after a direction inversion in
the frequency range 0 Hz to “Stop smooth” value (see the figure below).
