- 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 Encoder installation
1) Dualac2 and Dualac2&hp 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 +12V. It
can have different electronic output.
C11/C1 +5V/+12V positive of encoder power supply.
C12/C2 GND negative of encoder power supply.
C22/C13 A phase A of encoder.
C23/C14 B phase B of encoder.
2) Connection of encoder with open collector output; +5V power supply.
3) Connection of encoder with open collector output; +12V power supply.
U VERY IMPORTANT
It is necessary to specify in the order the type of encoder used, in terms of
power supply, electronic output and n° of pulses for revolution, because
