Product Line:
Altivar Machines, Altivar 212, S-Flex

Environment:
All models and serial numbers

Cause:
Wiring / Programming

Resolution:
This can be accomplished by programming VIA to function as a Logic input, as follows:
Press Mode to AUF (Quick Menu) Enter, scroll down and set LL (Low Limit) to your 1st preset
Mode back to AUF - scroll down to F - - - (Extended Menu) and press Enter
F109 = 2 (assigns VIA as a logic input)
F118 = 6 (assigns the preset speed function to VIA)
Mode back to AUF, scroll down to
SR1.. Enter and set to your desired High/Preset Speed
Close a contact between P24 and VIA to run at high/preset speed, open that contact to run at the LL - Low Speed setting
