Inovance AM600 Motion Controller System Integration and Troubleshooting Guide

In the field of high-end automation equipment, Inovance's AM600 series motion controller, with its powerful EtherCAT bus capability, flexible I/O scalability, and IEC 61131-3 standard programming environment, has become the core control unit for industries such as packaging, electronic manufacturing, robotics, and CNC machine tools. As equipment ages or production lines upgrade, engineers often face challenges such as controller replacement, program migration, EtherCAT network debugging, and axis control parameter optimization. This article is based on the official technical information of AM600, and provides an in-depth analysis of the hardware architecture, software tools, system integration points, typical fault diagnosis, and complete replacement process of the controller, helping on-site engineers quickly master maintenance and debugging methods.

Hardware Architecture and Model Identification of AM600 Controller

AM600 is a centralized motion controller with built-in PLC function. The main module adopts ARM Cortex A8 1 GHz processor and supports IEEE 754 double precision floating-point operation, ensuring the accuracy of complex trajectory calculation. The main hardware features are as follows:

EtherCAT Master Station: A standard EtherCAT port that can control up to 32 axes for point-to-point positioning, with a PTP refresh time of 4 ms; up to 8 axes can perform interpolation motion (straight line, arc, spiral line), and 16 axes can achieve electronic cam (CAM) control, with a synchronization period of 2 ms.

Built in communication interface:

Ethernet port (used for programming, debugging, and Modbus TCP master/slave)

Two RS485 interfaces (supporting Modbus RTU master/slave)

CANopen slave interface (also supports CANlink protocol)

Local I/O: 16 point high-speed input (up to 200 kHz, supports A/B phase pulse counting, pulse width/frequency measurement, accuracy ± 2 μ s), 8-point high-speed output.

Storage: 4 MByte user program storage, SD card slot for program backup and firmware upgrade.

Power supply: 24 VDC input.

Size: 80 x 90 x 95 mm (width x height x depth), suitable for installation in compact cabinets.

Scalability:

The main CPU module can connect up to 16 local I/O modules (DI/DO, AI/AO, etc.).

RTU-ECTA remote couplers can be mounted through the EtherCAT bus, with each coupler capable of expanding up to 125 modules (DI/DO/AI/AO) and supporting CoE services (PDO, SDO).

Replacement selection note: AM600 has different firmware versions, and when replacing, it is necessary to confirm that the firmware version of the new controller is compatible with the original application. If the original system uses a third-party EtherCAT slave device, the AM600 standard EtherCAT port supports connection, but the ESI file of the slave must be correctly configured in InoProShop.

Software tool InoProShop and project migration

The programming environment for AM600 is InoProShop (based on the Codesys kernel), which fully complies with the IEC 61131-3 standard and supports the following languages:

Structured Text (ST)

Ladder diagram (LD)

Sequential Function Diagram (SFC)

Continuous Function Diagram (CFC)

In addition, InoProShop integrates a CAM graphic editor that supports up to 65535 CAM points and can perform linear or fifth degree polynomial interpolation, simplifying electronic cam design.

2.1 Program Backup and Recovery

Backup steps:

Connect the PC to the Ethernet port of AM600 using a standard Ethernet cable (IP address needs to be in the same network segment, default may be 192.168.1. xxx).

Open InoProShop, scan devices on the network, and establish an online connection.

Execute "Online" → "Login" → "Upload" to upload the current program in the controller to the PC project.

Save the project as a. pro file and export device parameter configurations (such as EtherCAT slave list, axis parameters, PDO mapping).

Insert the SD card into the SD card slot of AM600 and backup the complete system image through InoProShop's "File" → "Store to SD Card".

Restore and replace:

After powering on the new AM600, connect it to the PC using the same Ethernet cable and scan the device through InoProShop.

If the IP address of the new controller is different from the original one, the IP address needs to be modified first (through "Device" → "Communication Settings").

After logging in, execute "Download" → "All" to write the original program and configuration into the new controller.

If an SD card image is used, the SD card can be inserted into a new controller while the power is off, and the system will automatically recover after power on.

2.2 Firmware Upgrade

The AM600 firmware can be upgraded online through SD card or InoProShop. Before upgrading, it is necessary to confirm that the new firmware version is compatible with the module being used (such as RTU-ECTA). The upgrade steps are as follows:

Download the firmware package (. bin file) corresponding to the AM600 model from the official website of Huichuan.

Copy the firmware file to the root directory of an SD card in FAT32 format.
