ZAPI ACE2 Controller Port Definition

（traction controller）

A1 Input KEY Input of the key switch signal.

A2 Output +5V Positive supply for external potentiometers and switches (+5V 100mA maximum).

A3 Input CPOT3 Analog input. By default it is used for the handbrake or the speedreduction request, like a digital input (0 – 5 V).

A4 Input FWD

Digital input, active when connected to +5V.

The default function is as FORWARD request; closing this input the truck moves forward.

A5 Input BWD  Digital input, active when connected to +5V.

The default function is as BACKWARD request; closing this input the truck moves backward.

A6 Input CPOT2 Analog input. By default it is used for the brake pedal or the quickinversion request, like a digital input (0 – 5 V).

A7 Input ENCA Channel A of the incremental encoder.

A8 Output PENC Positive supply for the encoder or for another speed transducer (+12 or +5 V, 150 mA maximum).

A9 Output NAUX1 Output of auxiliary-coil driver (driving to -B); PWM voltage

controlled; 2 A maximum continuous current.

A10 Input CPOT4

Analog input. By default it is used for the AUX1 request, like a

digital input (0 – 5 V); when it is high, output NAUX1 (A9) is activated.

A11 Comm. CANL2 Low-level signal of CAN bus interface 2.

A12 Comm. CANH2 High-level signal of CAN bus interface 2.

A13 Input CPOT ACC

Analog input. By default it is used as accelerator reference (wiper contact of the accelerator potentiometer).

A14 Input ENCB Channel B of the incremental encoder.

A15 Output GND Negative supply for the encoder and for potentiometers.

A16 Output NMC Output of the main-contactor driver (driving to -B);

PWM voltage controlled; 1.5A maximum continuous current.

A17 Output PCOM Connect the positive supply of coils (MC, EB, AUX) to this pin.

A18 Output NEB Output of the electromechanical-brake driver (driving to -B);

PWM voltage controlled; 1.5A maximum continuous current.

A19 Input SEAT Digital input, active when connected to +B.

The default function is as SEAT (or TILLER) input.

A20 Comm. CANL1 Low-level signal of CAN bus interface 1.

A21 Comm. CANH1 High-level signal of CAN bus interface 1.

A22 Sens. THMOT Positive terminal for the motor thermal sensor.

The internal pull-up is a fixed 2 mA current source (max 5 V).

A23 Sens. Negative terminal for the motor thermal sensor.
