First-time Setup

Configure the drive once over a USB-to-RS232 cable before use.

What you need

  • USB-to-RS232 cable

  • A computer running Chrome or Edge

  • 24V drive power

Wiring

The drive uses an RS232 port on an RJ45 connector — it looks like a LAN socket but is not a network port.

Warning

Never plug a LAN cable into this port. Same connector, completely different signals.

Pin assignment

Drive side (RJ45)

Computer side (DB9)

Function

Pin 3 — TX

Pin 2 — RX

Drive sends → computer receives

Pin 6 — RX

Pin 3 — TX

Computer sends → drive receives

Pin 4 — GND

Pin 5 — GND

Signal ground

All other pins are unused.

Important

TX and RX must cross over. A straight-through cable will not work.

Without the crossover both ends transmit at each other and nobody listens. You will be able to press Connect, but get no reply — the tool reports “no response (0 bytes received)”.

Modern computers have no DB9 port

You need a USB-to-RS232 adapter, then a DB9-to-RJ45 cable into the drive.

Computer ──USB── USB-to-RS232 adapter ──DB9── cable ──RJ45── Drive

A ready-made cable with USB on one end and RJ45 on the other is easier — the crossover is already handled by the manufacturer.

Note

The adapter needs a driver installed. If Connect finds no device, check that your computer recognises the adapter. Common chipsets are CH340, CP2102, FTDI.

If your controller uses RS485

The manual specifies an RS485-to-RS232 converter module in between — you cannot connect them directly, the signal standards differ.

Tip

The port label on the drive may read X2 or X3 — the manual is inconsistent between chapters. Look at the drive itself for the port marked RS232.

Steps

  1. Connect the cable from your computer to the drive’s RS232 port

  2. Open the drive configuration tool

  3. Press Connect and pick the device in the browser dialog

Warning

Always Read before you Write. Check the current value before overwriting it. Setting peak current above the motor’s rating will burn the motor.

About the COM ID — you do not need to know it

The COM ID field in the configuration tool defaults to 127, the broadcast address — you can connect without knowing what ID the drive is set to.

Tip

The first time you press Read, the tool reports which drive ID it found. No guessing, no trying numbers one at a time.

Leave it at 127 whenever you work with one drive at a time.

When you must change the ID

When several drives share one cable. Broadcast will not work — every drive answers at once and the replies collide.

Give each drive a unique ID (the valid range is 1–127), then enter that number instead of 127 to talk to a specific one.

Warning

Changing the COM ID means the controller can no longer find that drive until you update the controller side to match. Do not change it without reason.

Values that must match the controller

Setting

Value

Note

CAN Baudrate

50

Means 500 kbps — must match the controller

When finished, press Save and power-cycle the drive or the values are lost.
