CKD AxTools servo debugging software (EboDEX)

3. Table program

In terms of behavior units, each line can select "rotation command", "segment command", "return to origin", "coordinate system setting", etc., to set the target value, speed/time, and next line jump number. Supports copying, inserting, and deleting rows, similar to PLC's step ladder diagram.

6.2 Parameter Editing and Security Mechanisms

Before modifying any parameters, it is recommended to execute Reading → All data to backup all programs, parameters, and point tables in the drive to the PC. After editing is complete:

Use the Comparison function to compare the data in the editing area with the data in the drive, and the differences will be highlighted in red.

You can choose one-way copying (from drive to editing area, or from editing area to drive).

When executing Storage, confirmation boxes will pop up one by one, asking whether to overwrite existing program numbers.

Important: If the drive model in the editing area does not match the actual connection (for example, if you open an old TS file but connect it to a MU file), Storage will fail. At this point, it is necessary to first use the Change driver type to convert the parameter mapping (supporting conversion between eight models: TS/TH/MU/XS/GS/S/GH/H). After conversion, some parameters may be marked as "NG" or "N/A" and need to be manually re entered.

6.3 Origin offset setting

Two ways:

Manual rotating motor: In the servo OFF state (pay attention to safety and prevent the load from falling), jog the motor to the target mechanical position, and the software automatically calculates the offset.

Using the current position as the origin: First, run the motor to the ideal origin position in the servo ON state, and then execute this command to set it with one click.

The origin bias value is saved in the non-volatile memory of the driver and takes effect after powering on again.

Real time monitoring and troubleshooting (Monitor tab)

7.1 I/O signal waveform monitoring (Axio Function)

When it is necessary to check whether the external input and output (limit, emergency stop, start signal) are normal:

Click Axio Function → Monitor start.

Set the sampling frequency (up to 3000 times, input 999 for continuous).

Real time drawing of I/O status diagram (high and low levels) by software. Up to 21 signals can be selected, supporting normal mode (equidistant) or real-time mode (based on actual signal duration).

Drag and drop with the mouse to measure signal duration; Right click to display the time interval.

This function is particularly effective for debugging communication abnormalities in fieldbus such as CC Link.

7.2 Speed waveform acquisition (AxSpeed Function)

Used for observing acceleration and deceleration curves, steady-state errors:

Click AxSpeed Function → Set monitoring length (e.g. 500ms).

Choose single oscilloscope or dual oscilloscope mode to display both speed (green) and displacement deviation (yellow) simultaneously.

Click on Acquire waveform to trigger acquisition (applicable to motion in pulse train input mode).

The waveform chart supports scaling, cursor reading, and filtering smoothing. Up to 10 waveforms can be stored for comparing the effects before and after tuning.

7.3 Common alarms and resets

The Operation command in the Tool group can be used to execute tasks such as servo ON/OFF, program start/stop, single step operation, alarm reset, brake control, etc.

Alarm reset can clear the current alarm, but it should be noted that the servo may automatically power on after reset, and it is important to confirm safety.

If encountering an alarm that cannot be cleared (such as overload, overvoltage), the factory settings can be restored through APPRODEX initialization (note: this will erase all user programs and parameters).

Advanced features and practical skills

8.1 Terminal Mode

When the software interface cannot meet special requirements, it can enter terminal mode and directly send communication codes (ASCII format). For example, manually sending 'read current coordinates'. This mode also retains the last 100 historical records for easy retransmission.

8.2 Fieldbus Settings

For drivers equipped with CC Link, PROFIBUS, DeviceNet, EtherCAT, or EtherNet/IP interfaces, set the station number, IP address, etc. in 【 Set 】 → Field Bus setting. These parameters must be consistent with the main station configuration, otherwise communication will fail.

8.3 Data Backup and Recovery

File saving supports multiple extensions:. axa (fully integrated, recommended),. axw (waveform),. axs (speed),. axf (filter),. axi (I/O),. txt (NC program only).

It is recommended to save an. axa file after each debugging process and export the ACCODEX information (【 Set 】 ->ACCODEX information ->Save). The file should be in plain text format and can be viewed with Notepad for drive model, serial number, alarm history, etc.

Typical troubleshooting cases

Case 1: Unable to connect to drive

Check if the COM port is occupied (such as Mitsubishi PLC software).

Check if the cable is crossed (2-3 crossed, 5 straight connected).

Check if pins 7 and 9 of drive CN1 are suspended.
