Scale Factor
Menu Path MAIN SCREEN to CONFIG MENU to HARDWARE MENU SCALE
FACTOR
Purpose This function controls the number of increments into which one resolver revolution is
divided. A scale factor of 360 (0 to 359) allows the controller to operate in degrees. A
scale factor of 1024 (0 to 1023) allows positions to be programmed more accurately. In
some applications the scale factor can be set so each increment equals a unit of linear
travel.
Screen
Limits Scale factors range from two to 1024 on standard controllers. For controllers equipped
with the “-H” option, scale factor can be as high as 4096.
Recalculations When the scale factor is changed, all programmed setpoints are recalculated to convert
them to the new scale factor. The keypad/display will be inoperative until the calcula-
tions are done.
