“Manual” Speed Sources
The manual source for speed command to the drive is either the HIM requesting
manual control (see ALT Functions on page 101
) or the control terminal block
(analog input 1, 2, or MOP based on P96 [TB Man Ref Sel]) if a digital input is
programmed to “Auto/Manual”.
Changing Speed Sources
The selection of the active Speed Reference can be made through digital inputs,
DPI command, jog button or Auto/Manual HIM operation.
