How do I set up plus + and minus - speeds on the Altivar 61/71 drives?
Speed needs to be done using logic inputs to increase and decrease speed.
All models, all serial numbers
Set up Logic inputs LI5 and LI 6 for + and - speed inputs.
Set up the drive as follows: Wire one side of the switches to the +24v terminal and the other side of the minus switch to a logic input (example LI5) Wire the other side of the plus switch to a logic input (example LI6)
Program as follows:
RFC Ref 2 switching set to Ch2 active
RF2 Ref 2 channel set to UPdt + and - speed control.
UPd + /- speeds
USP= - speed input for LI5 or you can choose your logic input assignment.
dSP= + speed input for LI6 or you can choose your logic input assignment.
