EC-PG805-24 HTL Incremental Encoder PG
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.
