Product Overview

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.

Installation

Before installing the VFD, read through this manual carefully to ensure the proper installation and running with excellent performance and powerful functions into full play.

Step 1: Fixing the Expansion Module

Use the installation fixing hole to securely connect the expansion module to the control box.

Step 2: Wiring

Connect the encoder signal to the appropriate terminals on the expansion module. Use the RJ45 terminal for frequency-divided output selection and the KTY84 or PT100 signal input terminal for temperature detection.

Note : The disconnection detection function is only supported when the motor is running.

Installation and wiring

Installation precautions

Note

| The PG expansion module is recommended to be placed on expansion slot 1. If there is a second PG expansion module, it can be placed in other interfaces (expansion slot 2, expansion slot 3).

Required tools: Phillips screwdriver PH1, straight screwdriver SL3

Table Screw torque requirements

Dimensions

The dimensions of the PG expansion module is 73.5×103×34 mm (WHD).

Installation instructions

It is recommended to place t he 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 mod ule 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

Installation instructions

• Step 1 Disconnect all power supplies and disassemble all cables connected to the expansion module.
• Step 2 Use a Phillips screwdriver PH1 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.

When the KTY84 or PT100 two-wire system is used, short circuit PTB and PTC. (They are short connected by default.)

When the PT100 two-wire system is used, PTB and PTC do not need to be shorted.

Note:

• The part numbers of the PG extension module that supports the KTY84 type and that supports the PT100 type are different. Please note this when placing an order.
• The PG expansion module supports one PT100 or three PT100 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 PT100 temperature sensor application (in a 3-channel series connection), J3 should be shorted.

Wiring precautions

• 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 interferon ce 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.
