Working on a old 1336 force drive today and need to overspeed it a little bit. Looking at parameters 127-130 here http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1336t-um006_-en-p.pdf on PDF page 175 I have fwd and rev speed limts which in the drive are set to 2700 rpm on the fwd and 0.0 on the rev.
Then i have Max fwd and rev spd trim which is set to rev speed limit -1750 and Fwd 1750.
From the description of the parameters in the manual they appear to do the same thing which is limit speed but spd trim is after the trim has been added. Which parameter trumps the other. I am doing no trimming so is my max output speed going to be 1750 or 2700 if 1750 then what is the purpose of parm 127 ad 128?
Please Help.
