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.
