I have a motor that is capable of of an acceleration of more than 1'000'000 steps/sec^2. However, I cannot this high acceleration because the max. acceleration the internal motion engine of the PowerStep01 allows is 59590 steps/sec^2 (ACC Register, S...

When using the external step input of the Powerstep01, will the internal logic also use the advanced fast decay mode and switch between micro and fullsteps if a given speed limit is reached?Or does the step input only count microsteps and not using a...

For a project using several powerStep01 drivers it would be very useful, if each powerStep01 could be identified by a unique ID or a serial number. In the interface description no such register is defined. Is there maybe a hidden register available w...

According to the datasheet of the powerstep01 driver, a minimal baudrate of 5MHz has to be respected for the SPI interface. Is there any technical reason for that or can a lower (lets say <1MHz) baudrate be used for communication?

thanks, it does answer my question. The unique ID would have been handy to identify individual driver boards that are connected by a connector to the main MCU (e. g. for field returns, ect)

Thanks a lot for the answers, I was indeed a bit confused by the datasheet, since the max frequency is stated in the "min." column.
