Hi everyone.
I have just baught an L6 and am having a bit of trouble with. Though some of it is probably down to me I think that the arm is setup incorrectly.
From the RIOS opening screen if I click on ‘ALL=1.5ms’ to do the test where the arm should extend upright with the elbow at about 45°, it goes limp and drops down when I think it should be upright. Any one got any ideas?
Thanks in anticipation

Welcome,
I am taking a guess here, but this sounds like the classic power supply problem. That is when you tell all of the servos to move it causes the power to drop off to the SCC board which causes the processor in it to reboot. Not sure from your description what you are using for power.
An easy way to see if this is the problem (and a good way to run robots) is to seperate the logic power from the servo power. On the SCC remove the VL=VS jumper and then plug in a simple 9 volt battery into VL terminal and your other supply into the VS1 or VS2 battery terminal.
Good Luck

This is explained pretty well in steps 15 and 16 of the base assembly guide (the first time the SSC-32 is powered on.) 
“This will work 95% of the time without problems. However, if you notice the arm go limp or act erratic, you can power the microcontroller separately as illustrated in Figure 16.”

Sorry for the delay in replying, I’ve been on holiday.
I bought the arm second hand and don’t have and assembly drawing for the base, can anyone help? The power supply I’m currently using is a switchable mains type that I currently use at 6V is this correct? What exactly does putting 9V to VL do and what volltage should go to VS1?
Thanks in anticipation.
6V isn’t a problem but what its rated output current could be. If it is not enough to meet the load then the power supply will, in most cases, go into a current limited mode where it drops the output voltage to keep the current to some limit.
The SSC-32 has the ability to power it’s logic and the servos separately. If your servo power supply sags under load below about 5V it will reset the microcontroller on the SSC-32. When trying to troubleshoot these kinds of problems it is very helpful to remove the VL=VS1 jumper and supply the VL input from a common 9V rectangle battery. In this way the only servos will suffer (without damage) whatever the power problem is but the microcontroller remains operational. The 9V clip is usually supplied with the SSC-32 in the bag. You generally get upwards of 10 hours or more of operation from an alkaline battery.
Thanks for the replies. I will try a 9V battery on the VL terminal, this sounds favourite at the moment.
