How to calculate stall thresholds for a given motor?

2021-04-22
(Finally got the powerStep01 working)I have a Vexta PK266-02A stepper motor with has a phase resistance of 3.6Ωs. I am running the driver at 18V, and I am using the SPINFamily Evaluation tool. Whenever I issue a command, I promptly get an overcurre...

2021-04-05
My powerStep01 is constantly triggering the Overcurrent alarm whenever I give a movement command, even if there is no stepper connected. What could possibly be causing this? Previously I was getting a similar effect on the L6470 chip. When I turned o...

Where have all the powerStep01's gone?

Where have all the powerStep01's gone? The stock of the chip and even the Nucleo boards on every online site except eBay have run out. They all say zero. Has there been some sort of mass buy or did ST recall the product?

What is the default power on value of config register for L6480 stepper motor ic

2019-03-05
In the March 2015 datasheet it says that the hex reset value for the config register is 2C88. When I try this on my actual devices (4 of them) I get back 2C08. Based on the value this means that the OC_SD bit is set to 0 - Bridges do not shut down (...
