Appendix II How to use universal encoder expansion
card
III-1 Overview
PI500 is equipped with a variety of universal encoder expansion card (PG card), as an optional
accessory, it is necessary part for the inverter closed-loop vector control, please select PG card
according to the form of encoder output, the specific models are as follows:
ABZ incremental encoder:
Differential input PG card, without frequency dividing output.
OC input PG card, without frequency dividing output.5V，12V，
24V voltage is optional, please provide voltage and pulse input mode
information when ordering.
UVW incremental encoder.
UVW Differential input PG card, without frequency dividing
output.5V voltage
Rotational transformer PG card
ABZ incremental encoder.
OC input PG card, with 1:1 frequency dividing output.
5V，12V，24V voltage is optional, please provide voltage and pulse
input mode information when ordering.
III-2 Description of mechanical installation and control
terminals function
The expansion card specifications and terminal signals for each encoder are defined as follows:
