account thermal and voltage drop problems.

4 Can advantages:

The complexity of today systems needs more and more data, signal and

information must flow from a node to another. CAN is the solution to different

problems that arise from this complexity

- simplified design (readily available, multi sourced components and tools)

- lower costs (less and smaller cables )

- improved reliability (fewer connections)

- analysis of problems improved (easy connection with a pc to read the data

flowing through the cable).

4.2.4 Wirings: I/O connections

- After crimping the cable, verify that all strands are entrapped in the wire

barrel.

- Verify that all the crimped contacts are completely inserted on the connector

cavities.

U A cable connected to the wrong pin can lead to short circuits and failure;

so, before turning on the truck for the first time, verify with a multimeter the

continuity between the starting point and the end of a signal wire.

- For information about the mating connector pin assignment see the

paragraph “description of the connectors”.

4.2.5 Connection of the encoder

1) ACE2 card is fit for different types of encoder. To control AC motor with Zapi

inverter, it is necessary to install an incremental encoder with 2 phases

shifted of 90°. The encoder power supply can be +5 or +12 V. It can have

different electronic output.

A8 +5V/+12V positive of encoder power supply.

A15 GND negative of encoder power supply.

A7 ENC A phase A of encoder.

A14 ENC B phase B of encoder.

2) Connection of encoder with +5 V power supply.
