I have bought a BLDC motor with a controller and in the manual it says it the following about remote control:

CN17—analog input voltage connector, through the J2, J3 set is 0 ~ 5 V input or 0 ~ 10 V input;

is the pins on JP7-23 to 26 able to do this? (not using all of them)

also, i need to have a Potential free relay for emergency stop of the spindle, how is that connected to the Kflop?
and one last thing.. does anyone know how to control forward/reverse on this BLDC controller? (and maby use the tap mode)

i have included the manual to the BLDC motor and controller


extra info: i think that these motors was original sold by a company named "sangmutan" a couple of years ago if that helps with identifying it.
