Appendix II How to use universal encoder expansion card
(applicable for all series of Powtran frequency inverters)
II-1 Overview
PI9000 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.
II-2 Description of mechanical installation and control terminals
