DUALACE2 NEW GENERATION (dual traction)
Name Description
CHA_L Channel A of the left-hand side incremental encoder.
If connected to A31 (CANH), it introduces the 120 Ohm
CANT
termination resistance between CANL and CANH.
CHB_L Channel B of the left-hand side incremental encoder.
CHB_R Channel B of the right-hand side incremental encoder.
Negative supply for the right-hand side encoder, the right-hand
side thermal sensor and potentiometers.
Analog input 4.
CPOT
The default function is as reference for the proportional
EVP
electrovalve.
NCAN CAN bus negative reference. See paragraph 4.4.11
Positive supply for the high-side driver of pin PEB (A27). By
PIN
default, it is to be connected after the main contactor.
Driving output for the proportional electrovalve (driving to -B);
PWM current-controlled; 1.7 A maximum continuous current.
NEVP
Default function is as LOWERING valve.
Driving output for the line – or main – contactor (driving to -B);
NLC
PWM controlled; 2 A maximum continuous current.
Positive supply for the electromechanical brake and the
PEB electrovalves. It is supplied by PIN (A24) through a high-side
driver.
Driving output for the right-hand side electromechanical brake
NEB_R (driving to -B); PWM controlled; 3 A maximum continuous
current.
Driving output for the left-hand side electromechanical brake
NEB_L (driving to -B); PWM controlled; 3 A maximum continuous
current.
CANL Low-level CAN bus line.
CANH High-level CAN bus line.
Analog input for the thermal sensor of the right-hand side
traction motor.
PTH_R
Internal pull-up is a 2 mA current source (max 5 V).
