AKD BASIC drives provide all the performance features of our leading AKD Series, along with built-in machine and motion control that can be programmed in BASIC programming language from AKD WorkBench. These drives can eliminate the need for a separate PLC or allow machine designers to customize drive functionality.

Why does the connection on my PC say Limited or no connectivity available and display a warning symbol at the local area connection icon in Windows?

Although Windows displays this message and the limited functionality icon for the drive connection, your PC can communicate fully with the drive. This message and the icon are normal for an AKD to PC connection.

Why does the background color of some of the screens in Workbench appear gray?

This is because you are using the Windows classic theme. To get a white background you must change the theme that Windows is using.

To change the theme go to the Control Panel, select Display, select the Themes tab, and choose a new theme, such as "Windows XP".

Why can't workbench find my drive on the network?

See Device not Shown in the Workbench Help for a detailed discussion of this problem.

Why can't I see my AKD drive when I try to connect in Workbench?

If you are communicating through the Ethernet port at connector X11, you might not see your drive in the connect window for any of the following reasons:

  • Poor cable connection. Make certain you have a good connection between your computer and the drive by checking to see if you see a blinking light next to the connector (at each end).
  • Improper rotary switch setting. Make certain that the S1 and S2 rotary switches on the front of the drive are set to 0 (bottom position), unless you are attempting a point to point connection and your computer is set up to connect in this manner.
  • Conflict with another device that is networked to your computer (including your wireless connection). In some cases, turning off your wireless card will fix this. You can turn your wireless card back on after you establish communication with the AKD).
  • Improper TCP/IP settings. Make certain that the TCP/IP settings in the network port that you are communicating through are working properly.
What if I cannot connect to my drive using WorkBench, but I have been advised to download new firmware to the drive to fix the problem?

In most cases, firmware is downloaded using WorkBench without setting the hardware into a specific “download” state. If you need to download firmware, but are unable to connect to WorkBench, use the procedure described in Forcing the drive into firmware download mode in the Workbench help.

The drive is running rough and noisy after autotuning procedure. What can I do?

Autotuning of your application delivered unexpected results while tuning the current feed forward value. Please deactivate "Tune Acceleration FF" in the Workbench Performance Servo Tuner screen and restart the tuning.

How long does it take until foldback is totally recovered?

Up to 500 s depending on the active current. See page Foldback Times.

How long can the drive sustain a constant current above Icont before faulting?

5 seconds with Ipeak. Smaller currents can be sustained for longer periods. See Foldback Times.

How do I view parameter information from Workbench screens?

There are two ways to find out about what parameter is behind a text box in Workbench.

  1. Right click on the text box and select Parameter Info from the menu. A popup appears next to the window selected. Note if you clicked the Help, you get taken to the page in the help system. Pressing F1 also does the same.
  2. Click the “Tell me more about this topic” link at the top of each page.
