20B7EL25
Traction controller 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
Á
. The encoder power
supply can be +12V. It can have different electronic output.
A1 : +12V : Positive of encoder power supply.
A2 : GND : Negative of encoder power supply.
A13 : A : Phase A of encoder.
A14 : B : Phase B of encoder.
Connection of encoder with open collector output; +5V power supply.

The encoder power supply voltage and output electronic has to be communicated to ZAPI in
order to correctly set the selection jumpers in the logic card.
