Re: Startup of the RoboClaw 2x60

It should not move during power up unless homing has been enabled. PLease check if it happens in other modes on your board. I will test it here as well.

Also what are you using to provide the analog signal and how is it wired to the roboclaw?

Re: Commands 65 and 66 seem hobbled.

Did you test that positon control is working correctly in IonMotion(eg using the Position Settings window)? Velocity commands(including the distance commands) do not require the Position PID values to be tuned properly or even setup, but the Position commands do require them to be setup. Please chec...

Re: Potential issue with Position Tuning in IONmotion

2. Page Up/Down use to be the big movements while the errow keys were the small movements but I wanted reasonable movements on the arrows(eg more than 1) but I still wanted high resolution movements(hense the page up/down setting). 3-4. I've added the check box options and will be updating the insta...

Re: Potential issue with Position Tuning in IONmotion

1. There is a setting that is wrong in the current release of IonMotion. One motor is set to buffer commands sent to it and the other is not. I suspect that is why you are seeing some differences. Not necessarily all differences but some between the two. Im working on an update that also make some m...

Re: How to determine QPPS with less than 100% duty.

Run at X% then multiple the speed by 100 and divide by X. Motor speed is fairly linear relative to voltage. Duty cycle is basically voltage percentage,

For example if you run at 20% power and get a speed of 2000 then the QPPS is approx 10000.

Re: Reading current with Roboclaw

If you just need to use it as a cutoff value then you should be able to calibrate the reading that matches your physically requirement. The reading should be consistent even if it is off by some offset or slope error. Im guessing you have a Roboclaw 2x30A? Those have a peak current limit of 60amps a...

Re: Minimum Logic Battery Voltage

Depending when we order headers they can be slighly different. There are a couple different manufacturers we use. But they should have no effect on the voltage rading. However there are errors in the voltage divider resistor resistances. All resistors have some varience. But I dont think that has an...

Re: Reading current with Roboclaw

Another thing that can affect the current reading is the drive method. Locked Antiphase tends to have more noise near full power while Sign magntiude tends to have it at the low power. The current reading is timed to take place in the middle of the high side pulses. For sign magnitude this means the...
