Hello,
I have a couple of these drives I want to use but do not have the deffinition of the pinout abbreviations. I can get the spindle to turn slowly by inputing a 5v dc signal on the srv or sfr terminals but that is all I get. The pin 13 command signal only reads about .6 volts witch makes sense for the slow speed. I am not seeing how to control the spindle speed with a 0 to 10 volt input ? Any help appreciated.
Thanks,
Scott
