Why does the speed pot cause my drive to run in reverse?

Published date: 27 February 2019

Drive is running at Low Speed, or 0Hz when scaled to 100% and then runs up to 60Hz or High Speed when at 0%. 

Product Line:
All Altivar drives


Incorrect wiring

For the drive to run forward, the Analog inputs are polarity sensitive.  The Output, or wiper contact from the drive needs to be on the analog input terminal.  If you are seeing the scaling when adjusting from 0-100% then you may just need to swap the +10 and COM wires to change the polarity.
