ATV312 configuration for forward and reverse using +10/-10V speed reference
Altivar 312 series drives.
All models, All serial numbers.
Customer needs to control the drive forward and reverse with a single run command and +10 to -10V input for speed/direction control.
AI2 input can be used for +10 to -10V input. Configure parameter FR1 to AI2 under the CTL menu to have the drive look at AI2 as the primary speed reference. Connect your +10/-10V speed reference between AI2 and COM on the drive.
