AF6ZP0CA – COMBIAC0 & ACE0 2uC – User Manual Page – 19/155
Pin Type Name Description
A1 Input DI0
Digital input DI0.
The input is activated when it is connected to +B. With the logic
hardware properly configured it can be used to supply the positive
terminals of EB and MC.
The default function is as TILLER input.
A2 Output PEB
Positive supply of the electromechanical brake. For the 24V
version only, it is supplied through a high-side driver.
A3 Input PEV
Positive supply of electrovalves: EV1, EV2, EV3, EV4, EV5,
EVP1, EVP2, HORN. With the hardware properly configured, it
can be used to supply the positive terminal of EB.
This input is to be supplied with positive voltage taken after main
contactor.
A4 Output NEB
Driving output for the electromechanical brake (driving to -B);
PWM controlled; 2 A maximum continuous current.
A5 Output NENC
Negative supply for external devices (encoder, potentiometers,
etc.)
A6 Input DI2
Digital input DI2.
The input is activated when the external switch is closed.
By default, if HARD & SOFT option is ON (see 8.2.2Errore.
L'origine riferimento non è stata trovata.), the H&S function is
activated when the switch is closed.
A7 Input DI1
Digital input DI1. Active high.
The input is activated when it is connected to +B.
The default function is as QI/PB input (quick inversion/pedal
brake). Closing the switch quick inversion function is activated.
A8 Output
EV 5 /
PPOT
Driving output for the on/off electrovalve EV5; 1 A maximum
continuous current (driving to -B).
Depending on internal jumper configuration it can be used as
positive supply for external devices (+12V/+5V, max150 mA).
A9 Output EV1
Driving output for the on/off electrovalve EV1 (driving to -B); 1 A
maximum continuous current.
A10 Input KEY Input of the key switch signal.
A11 Output EV2
Driving output for the PWM voltage-controlled electrovalve EV2
(driving to -B); 1 A maximum continuous current.
A12 Output NMC
Driving output for the main contactor (driving to -B); PWM voltage-
controlled; 1 A maximum continuous current.
A13 Input ENCB Phase B of the traction motor encoder.
A14 Input ENCA Phase A of the traction motor encoder.
