Title: What is Step Pulse / Dir Pulse?
Post by: kolias on February 23, 2017, 07:33:20 PM

Cant find any info on the manual but would like to know what the values for “Step Pulse” & “Dir Pulse” do to a stepper motor in the Motor Tuning and Setup Screen

Are any guidelines on the settings? (the screen shows 1-5us)

Its the length of pulse output to the controller - too short and the motor drive simply will not see the pulse or it may see some pulses but not others, its all about signal timing.

Its a square-wave signal, the output voltage goes up and down with a period - the pulse length controls the length of that period.

Normally a value of 3-5 works it seems.
