3.6 ENCODER INSTALLATION
1) AC1 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.
A9 +5V/+12V positive of encoder power supply.
A10 GND negative of encoder power supply.
A19 A phase A of encoder.
A20 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.
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.
