TSERV Service advisory timer
0 0 1000
Set to a value X greater than 0 if you wish the
“Service Advisory” icon to be displayed every
X hours of machine running time (according
to the main operating time counter). To
reset the hour counter for the icon display
countdown (until the next service advisory),

seconds with the display on the “SERVICE
MENU” page.
AR Maximum acceleration ramp (sec.) 0.5 sec. 1.5 sec. 5 sec.
Increase to obtain a less abrupt response
when accelerating, and vice versa.
DR
Maximum deceleration
ramp (sec.)
DISC 0.5 sec. 1.5 sec. 8 sec.
Increase to obtain a less abrupt response
when decelerating, and vice versa.
WARNING: increasing this value increases
the braking distance.
REV 0.5 sec. 2.5 sec. 8 sec.
IR
Maximum deceleration ramp in
reverse (sec.)
0.5 sec. 0.5 sec. 5 sec.
This is the maximum current which can be
supplied to the disc brush deck.
WARNING: increasing this value increases
the risk of the motors overheating.
VS1 Brush 1 motor protection threshold 20A 30A 50A
This is the maximum current which can be
supplied to the disc brush deck.
WARNING: increasing this value increases
the risk of the motors overheating.
VS2 Brush 2 motor protection threshold 20A 40A 50A
This is the maximum current which can be
supplied to the cylindrical brush deck.
WARNING: increasing this value increases
the risk of the motors overheating.
VDEAD Paddle potentiometer dead zone 0.0V 0.1V 1.0V
Increase if the alarm T3 appears in the rest
position and it is not possible to adjust the
system’s mechanics. (Speed regulation will,
however, be more difcult to modulate)
INOM Nominal drive current 10A 15A 15A
This is the maximum continuous current
which can be supplied to the electric wheel
drive unit.
WARNING: increasing this value increases
the risk of the motor overheating.
IMAX Maximum drive current 10A 45A 45A
This is the maximum instantaneous current
which can be supplied to the electric wheel
drive unit.
WARNING: increasing this value increases
the risk of the motor overheating.
TMAX Protection trip time for IMAX 0 sec. 12 sec. 60 sec.
This is the reaction time of the electric wheel
drive unit protection device when overloaded:
this parameter is used in conjunction
with IMAX to obtain the most appropriate
response curve for the overload protection
motor actuation system.
WARNING: increasing this value increases
the risk of the motor overheating.
