Re: PM-30mvl stepper/driver selection question
If you want to go 50V or 60v then the KL34H280-45-4A should be fine. The Z will be a bit slower but still OK.
The 900 oz does not come in a lower inductance or higher current but you can get the 640 oz with a higher inductance of 6.8mH if you want to run a higher voltage.
I have found that Gecko voltage formula is a bit underrated. The 5.1A 640 ox is fine at 60V and the some what low inductance 900 oz will work fine at 60V.
You can save a little money by using the 60V drives all the way around.
