5.1.6 Offset tuning
If the FlexDrive
II
will be using analog input 0 (AIN0) as a demand reference input (or for any
other purpose) you may wish to perform offset tuning before continuing. The purpose of offset
tuning is to remove DC offset voltages on the demand reference input to achieve a stationary
motor shaft with 0VDC at the input. Offset tuning is controlled by DIP switches 7 and 8.
Before starting, confirm that the device supplying the AIN0 demand input is set to its intended
zero output setting (nominally 0VDC).
