I am using the uc300eth UB1 with AM882 Leadshine stepper motor drive, as I understand from the Leadshine manual I have to use 2k resistors for the PUL- , DIR-,ENA- and alarm since I use 24volt outputs of UC300 eth ub1 right?
Can someone explain why the resistors are connected to - lines? Is that safe for the drivers? I have seen some diagrams connecting resistors at the + lines for protecting the drivers but this is the first time that I see the opposite.
