Prosimu T1000 T5 rear actuators stop working

Hi All,

I'm working with a Prosimu T1000 5dof.

Within a few minutes of the cockpit running the rear left actuator simply stops working.

It does this with both iRacing and Assetto Corsa

The ProSimu documentation says I should limit the actuators to 65%, output rate to 1ms, and each DOF at 60%. I've done all of this and even reduced the rates to 50% and within 10 mins of use the rears stop working and wont work until I've shut the platform down at the mains power and restarted all software.

Any help would be greatly appreciated

It seems that your actuators have a internal problem, try to swap your actuators. If it's always the same, return the actuator to us and we will try to fix it. You have old version with Dyadic actuators 100 100

With the new version of T1000 5 motion, we have the PRS 200.

Thanks

Thank you all for your help and ideas.

I swapped the front for the back actuators and all was well until I had someone who weighed around 100kg in the cockpit. After a spell in No Limits 2 the right rear actuator stopped working. I shut down the power to the platform, re started it and restarted the software.

I then drove in Assetto Corsa for a spell and the left rear stopped and required the same procedure.

I don't understand how if each actuator is good for 100kg, and I have four of them, how do the rears keep overloading even when they're restricted to 65% of their travel and 60% of their speed??

With a 'heavy' pilot, it's likely that the balance of the system shifts to the back of the rig and overloads the rear actuators - inertia is not your friend .

OK,

So I'd have considered 100kg's an average weight. What's the limiting factor in allowing for extra weight? Would it reducing the throw of the actuators further?

Another thought I'd had was to move the cockpit and seated position forward on the chassis so the heaviest part of the payload (the driver) was in the middle of the actuators.

I initially balanced my sim capsule+myself in my 6DOF (Stewart Platform) with three cheap scales, you could try the same with four - one under each actuator - if possible?. Better then trying to guess what is going on, although you would think the design would have taken all this into account.

For the money I’d expected everything to just work
