Expansion Module User Manual
Preface
Thank you for choosing INVT EC-PG805-24 HTL incremental encoder PG expansion
module.
The EC-PG805-24 HTL incremental encoder PG expansion module is used with the GD880
series VFD control box to detect the HTL incremental encoder. The expansion module
monitors the rotational speed of the motor by detecting the output signal of the encoder,
providing real-time speed feedback for precise speed control.
This manual describes the product overview, installation, wiring, and commissioning
instructions. Before installing the VFD, read through this manual carefully to ensure the
proper installation and running with the excellent performance and powerful functions
into full play.

2.6 Wiring precautions
Note:
For the encoder wiring inside the cabinet, separate them from strong interference
cables (like power cables) with a recommended interval of 30cm.
For the encoder wiring outside the cabinet, avoid parallel wiring with the power cable
and avoid forming a ring shape. If conditions permit, it is recommended to use a metal
conduit for wiring.
To ensure high anti-interference capability in closed-loop control, you need to use a
shielded wire for encoder cables and ground both ends of the cable, that is, connect the
shielding layer on the motor side to the motor housing and connect the shielding layer
on the PG module side to the PE terminal.
