4.2.5 Connection of the encoder
1) COMBIACX/ ACEX card is fit for different types of encoder. To control an AC
motor with the Zapi inverter, it is necessary to install an incremental encoder
with 2 phases shifted of 90°. The encoder power supply can be +5V or +12V. It
can have different electronic output.
D2 +5V / +12V positive of encoder power supply.
D5 GND negative of encoder power supply.
D1 A phase A of encoder.
D4 B phase B of encoder.
2) Connection of encoder with open collector output; +5V and +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 the
logic unit must be set in the correct way by Zapi.
The n° of pulses revolution the controller can handle is given by the second-
last letter in the software release name (see 3.5).
