Re: Can I change the batteries?

Hi Craig,
thank you for reply. This mean that I can't change the motor's battery due to the proprietary protocol, right? Is there nothing that I can do?

Can I change the batteries?

Hello, I'm working with an RMP 440 LE and I need to change the batteries with somethings else that I've developed. I saw that there's a board under OCU that control the central battery (ABB board, I suppose). What type of protocol I have to use to communicate with the ABB board from my battery? SMB ...

maximum motor's torque

Hello,
I'm unsing an RMP 440 LE. What is the maximum motor's tork? Can I mount tires with bigger diameter (say 70 cm with a payload of 60 kg?)

Thank you

Re: battery autonomy

I understand your point of view. So I will try to monitor the soc parameter.

Thank you

Re: Is there a stop command?

Hi Craig,
I found my mistake: when I tried to set 0 I haven't taken in account that the mantissa have an hidden 1 in IEEE 754.

With 0x0000000 the rmp stop correctly

Thank you for the support

Re: Is there a stop command?

Hi Craig, I'm sorry if I confused you. I try to explain better what I mean. From a standing start, if I send a motion command with value 0, the rmp start to move as I send the same command with 1 (so at the maximum velocity). This happens in any situation, whether to send a velocity command or to se...

Re: Is there a stop command?

Hello Craig, now I'm using acceleration based mapping and the decel acceleration limit is set at 3.923 mps2. I've attached the traffic on can bus (in figure on the right) after send a motion command (in figure on the left) where I set yaw rate to 0.0 and velocity to 0.1. I use the follow parameters ...

Re: battery autonomy

Hello Craig, I would like to know the rmp's autonomy in difference situations, so I'm estimating it by monitoring the current per motor. If I do so I don't have to spend a lot of time discarding the battery for every scenario. So, if I take the max avarage current I can predict how long take the bat...

battery autonomy

Hello,
I'm working with rmp440 le with 70 kg as payload and I need to know how long the battery runs down. I know that it's depend on several factor, so is there some application note about it? Otherwise, can someone provide me some reference data?

Thank you

Re: transmission ratio question

Hi Chris,
thank you for the aswer. Maybe I have some problem with tourque. Which gearbox do you have available? Can I upgrade my rmp 440le on my own?
