Warning Message of CYSTD

[peter.zhang]

Dear all,
"Unable to communicate with CySTD (0). Cycle the panel and re-start acquisition." pops up when we powered up the tool to +/- 120VDC to open or close the motor. We changed to another Warrior Panel and another laptop but no difference.
Another tool is good if we power on quickly.
Could you tell me is that warning message related to tool problem?

Loss of comuninications in this manner is normally caused by a current surge that puts a spike on the usb signals. Check the USB cable connections and routing of USB cable
