BXSD-120A Communication Port Damage

Postby bgmathes » Thu Jul 13, 2017 7:16 pm

Hello
I have two new BXSD-120A "Drives that the com. port has gotten damaged internally after connecting the communications cable to CN6.
Initially both drives communicated, then quit communicating at some point.
With one of them, it caused a fuse to blow in our DC Power supply that supplies I/O power to CN5 and CN7. After this happened
we replaced the communications cable with a spare cable we had, but the com. port would no longer work.
What is going on?

Hi bgmathes,

In regards to your post, it sounds like the communication port (CN6) and the CN5/CN7 connectors have been damaged. Page 43 of the manual shows a caution note for the CN6 communication port:

We offer an RMA process which you can do in order to have us inspect the drivers. However, the inspection would only conclude if the drivers have been damaged. In the event that the drivers are damaged, replacement drivers will be needed.


To avoid this issue from happening in the future, you must keep negative ground for both the power supply and the driver. To do this, connect the FG of the power supply and BX driver.

Please explain grounding further. Does the 0V of our DC power supply need to be grounded to field ground?

Hi bgmathes,

You can reference an example of the motor and driver installation and wiring from page 161 of the BX2 series manual which I have linked below:

You will need to ground the motor, driver, AC power supply and the 0 VDC of the 24 VDC power supply when using an external power supply for the CN5/CN7 connectors.
