INVT Incremental Encoder Pg Expansion Module
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.
Product features
- Incremental encoder multi-channel signal detection: IA+, IA -, IB+, IB -, IZ+, IZ-
- Provides power supply for encoders: 15V ± 5% or 24V ± 5%/150mA
- Supports 3 input signal types: open collector, push-pull, differential
- Supports pulse reference and frequency division output
- With the encoder disconnection detection function, avoiding the expansion of system fault impact
- Able to detect the motor temperature through the KTY84/PT100 temperature sensor signal
- Adopts digital filtering technology to improve electromagnetic compatibility and realize long-distance stable reception of encoder signals

Installation precautions
Dimensions
The dimensions of the PG expansion module is 73.5X 103X34 mm (W*H*D).
Installation instructions
It is recommended to place the PG expansion module at expansion slot 1 of the control box.
The following is an example of the installation at slot 1.
- Step 1 Place the expansion module in the corresponding position of the control box expansion slot 1, align it with the slot, and then buckle it together.
- Step 2 Align the expansion module positioning hole with the positioning stud.
- Step 3 Fix with a M3 screw. The installation is complete.
Note:
- The expansion module and control box are electrically connected through slots. Please install them in place.
- To ensure the reliable operation of the expansion module and meet EMC requirements, please tighten the screws according to the recommended torque for reliable grounding.
Disassembly instructions
You can disassembly the module by reversing the order of steps described in section 2.3 Installation instructions.
- Step 1 Disconnect all power supplies and disassemble all cables connected to the expansion module.
- Step 2 Use a Phillips screwdriver PHl to remove the grounding screws of the expansion module.
- Step 3 Lift the expansion module out of the control box positioning stud and pull it out to a suitable position. Disassembly is complete.
User’s wiring terminal
Note:
- The part number of the PG extension module that supports KTY84 type and that supports P T 100 type are different. Please note this when placing an order.
- The PG expansion module supports one PTIOO or three P T 100 for use in series.
The EC-PG805-24 PG expansion modules is configured with a pull-up resistor and can work in combination with multiple types of incremental encoders through various external wiring modes. For the wiring methods, see Figure 2-3, Figure 2-4, Figure 2-5.
Note: For the PTIOO temperature sensor application (in a 3-channel series connection), J3 should be shorted.
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.
