Panel mount Encoder Part Number: 77-9511-1. This encoder controls the Speed Set Point (speed knob on the front stinger of the WT-30)
DL Encoder 1000PPR Part Number: 80-6018. This encoder controls the Actual Speed (encoder drive roll)
If you turn the speed knob and the Speed Set Point does NOT change, then you need a new Panel Mount Encoder. Especially if you can manually change the speed set point via the touchscreen.
