"an over current occurred"
« on: May 29, 2018, 03:13:41 PM »
Twice in the past,, the notice "an over current occurred" has appeared on my PSR 970. The first time it happened I got really scared. But, thankfully, nothing serious, happened. However, I am keen to avoid doing the wrong thing, in future,  and welcome members' comments on this post.

Do you mean by Over Current an electrical surge. It is always best with most keyboards to use Anti Surge Plugs.

Hi --

I'm assuming that the overcurrent message appeared after plugging a device into the USB-A port.

A USB (host or USB-A) port supplies a limited amount of electrical current. The USB hardware detects an attempt to draw more current than allowed and shuts down the port. The overcurrent condition is reported to software, so software can report the condition to the user.

I wouldn't expect any issues (Yamaha are good engineers). However, please take notice of the power hungry USB device and stop using it. Replace it with a less demanding device.

More details would help analysis.

Hope this helps -- pj

I did a search in both the owners manual and service manual for any error codes or messages related to 'over current' and found none. 
Does the keyboard continue to function or does it stop working and need to be powered off to reset it? When this occurs are you playing through the internal speakers, perhaps set a bit loud (maybe with much bass content) which may take more electrical current?

Thanks MarkF48 , PJD and Eileen.Yes, the incident is definitely related to the USB. I had a USB  Hub plugged in.My USB Hub has 4 switches on it. I think sometimes I am  a bit impatient switching off one thumb drive in the Hub, and switching on another thumb drive.  Fortunately, i have not had to power off, or reset my keyboard.  I have made a promise to myself that in future I will slow down. Computers these days, respond so quickly,that I have grown to expect everything to happen instantaneously, and, maybe like us, they need a moment to gather their thoughts, and regroup.

I have exactly the same 4-switch hub set-up and I incurred exactly the same set of circumstances just the other day. As you say, I must slow down a bit when switching between usbs.

I forgot to mention in my first post on this subject that my HUB  is plugged into my laptop, and not into the 240 volt power point in our house.

Just to clarify a couple things...

- Is the HUB is plugged into and powered by the laptop so the keyboard and perhaps some other devices are connected to the laptop, such as the keyboard is plugged into one of the 4 ports(?)

- I have had my own computer pop up an 'Over Current' message when a USB hub had a problem (HUB was intermittently defective). Was it your laptop that gave the message with the S970 connected to the HUB or was it actually the S970 that gave the 'Over Current' message.

No laptops were involved in my instance.

I think they only recommend using two USB ports in the S Series.

They do. I use a switchable 4-port hub to save unnecessary plugging in and out of memory sticks, I just make sure that no more than two if the usbs are connected to the arranger at any one time.

YammyFan,

You don't need to use a powered USB HUB.  A passive HUB will do just fine. I have one of those HUBs with 4 switch Ports on it but there is no power required.  The keyboard will supply enough power.

Thanks everyone for your posts on this subject.  I saw the  notice "an overcurrent occurred" appear on my PSR  970  [Not on my laptop]
I'm very, very happy with my usb  HUB which gains its power from my PSR 970. I try to  always have only one switch  on my Hub on at a time.
