5.3 DESCRIPTION OF PARAMETERS THAT MAY BE PROGRAMMED
In addition to the Configuration, Parameter settings may be made by Zapi using
standard default settings, settings to Customer Specifications, or the customer may
make changes according to the application, using a Digital Console.
During the setting up procedure on the machine, the Console can remain connected to
the chopper during travel. The Parameters can be modified in real time, during
operation.
Pay attention to the polarity of the Console Connector. Refer to Page 15 of this Manual
for connection details.
THE PROGRAMMING CONSOLE MUST BE PLUGGED ONLY WHEN THE
KEY-SWITCH IS OFF.
The following Parameters can be modified :
1 ACC. DELAY
= Determines the acceleration ramp.
2 DECELER DELAY
= Determines the deceleration ramp according to the accelerator
pedal position.
3 RELEASE BRAKING
= Determines the deceleration ramp when the travel request
is released.
4 INVERSION BRAKING
= Determines the deceleration ramp when the Direction
Switch is inverted during travel.
5 CUTBACK SPEED
1
= First speed reduction, active when H&S is active.
6 CUTBACK SPEED 2
= Second speed reduction, active when DIGITAL INPUT2 is
active.
7 MAX SPEED FORW
= Maximum Forward Speed, obtained by weakening the Field
Current after it has reached 100% conduction of the Armature. With the Parameter
set at level 0, the armature is in total conduction but the field current does not
decrease below the Nominal value (low speed).
8 MAX SP. FWD FINE
= Maximum forward speed.Fine adjustment.
9 MAX SPEED BACK
= Maximum Reverse Speed, obtained by weakening the Field
Current after it has reached 100% conduction of the Armature. With the Parameter
set at level 0, the armature is in total conduction but the field current does not
decrease below the Nominal value (low speed).
10 MAX SP. BWD FINE
= Maximum reverse speed. Fine adjustment.
11 TRACTION I MAX =
Maximum controller current.
12 ARMA NOM.CURR.
= Nominal Armature Current. This parameter fixes a limit for
the armature current above which the Field Current is at least the Nominal Value
(FIELD NOM.CURR.), regardless of accelerator position.
13 WEAK DROPOUT
= This Parameter fixes a limit on the Armature Current above
which the Field Current is increased linearly up to the Nominal Field Current (in
proportion to the armature current).
