Pin
Type
Name
Description
A3
Input
CPOT
Analog input 1.
The default function is as accelerator reference (wiper contact of
the accelerator potentiometer).
A4
Input
FW
Digital input active when connected to +B.
The default function is as forward request; closing this input the
truck moves forward.
A5
Input
BW
Digital input active when connected to +B.
The default function is as backward request; closing this input
the truck moves backward.
A6
Input
SEAT
Digital input active when connected to -B.
The default function is as seat (or tiller) input.
A7
Input
CHA_R
Channel A of the right-hand side incremental encoder.
A8
Output
PENC_R
Positive supply for the right-hand side encoder and for
potentiometers (+5 V or +12 V, 200 mA maximum).
A9
Output
NENC_L
Negative supply for the left-hand side encoder, the left-hand side
thermal sensor and potentiometers.
A10
Input
CPOT BR
Analog input 2.
The default function is as breaking reference (wiper contact of
the brake potentiometer).
A11
Input
CHA_L
Channel A of the left-hand side incremental encoder.
A12
Output
CANT
If connected to A31 (CANH), it introduces the 120 Ohm
termination resistance between CANL and CANH.
A13
Input
CHB_L
Channel B of the left-hand side incremental encoder.
A14
Input
CHB_R
Channel B of the right-hand side incremental encoder.
A15
Output
NENC_R
Negative supply for the right-hand side encoder, the right-hand
side thermal sensor and potentiometers.
A16
Output
NLC
Driving output for the line – or main – contactor (driving to -B);
PWM controlled; 2 A maximum continuous current.
A17
Output
PEB
Connecting this pin to the positive supply of electromechanical
brakes and proportional electrovalve closes the recirculating path
for the built-in freewheeling diodes.
A18
Output
NEB_R
Driving output for the right-hand side electromechanical brake
(driving to -B); PWM controlled; 3 A maximum continuous
current.
