Pin
Type
Name
Description
A17
Input
CHA_L
Channel A of the left-hand side incremental encoder.
A18
Output
CANT
If connected to A31 (CANH), it introduces the 120 Ohm
termination resistance between CANL and CANH.
A19
Input
CHB_L
Channel B of the left-hand side incremental encoder.
A20
Input
CHB_R
Channel B of the right-hand side incremental encoder.
A21
Output
NENC_R
Negative supply for the right-hand side encoder, the right-hand
side thermal sensor and potentiometers.
A22
Input
CPOT
EVP
Analog input 4.
The default function is as reference for the proportional
electrovalve.
A23
Input
NCAN
CAN bus negative reference. See paragraph 4.4.11
A24
Input
PIN
Positive supply for the high-side driver of pin PEB (A27). By
default, it is to be connected after the main contactor.
A25
Output
NEVP
Driving output for the proportional electrovalve (driving to -B);
PWM current-controlled; 1.7 A maximum continuous current.
Default function is as LOWERING valve.
A26
Output
NLC
Driving output for the line – or main – contactor (driving to -B);
PWM controlled; 2 A maximum continuous current.
A27
Output
PEB
Positive supply for the electromechanical brake and the
electrovalves. It is supplied by PIN (A24) through a high-side
driver.
A28
Output
NEB_R
Driving output for the right-hand side electromechanical brake
(driving to -B); PWM controlled; 3 A maximum continuous
current.
A29
Output
NEB_L
Driving output for the left-hand side electromechanical brake
(driving to -B); PWM controlled; 3 A maximum continuous
current.
A30
Output
CANL
Low-level CAN bus line.
A31
Output
CANH
High-level CAN bus line.
A32
Input
PTH_R
Analog input for the thermal sensor of the right-hand side
traction motor.
Internal pull-up is a 2 mA current source (max 5 V).
