Rockwell Automation 20A PowerFlex 70EC/700VC - Manual (Page 17)

Auto/Manual 13
Auto/Manual The purpose of the Auto/Manual function is to permit temporary override of speed
control, or both speed control and start (run)/stop control. Each connected HIM or
the control terminal block is capable of performing this function. However, only
one device may own “Manual” control and must release the drive back to “Auto”
control before another device can be granted “Manual” control. The network or
digital input control function named “local,” has priority over the Auto/Manual
function.
The HIM can request or release Manual control by pressing the “Alt” key followed
by the “Auto/Man” key. When the HIM is granted manual control, the drive uses the
speed reference in the HIM. If desired, the auto speed reference can be
automatically preloaded into the HIM when entering HIM manual control, so that
the transition is smooth.
To use manual control from the terminal block, a digital input must be programmed
to the “Auto/Man” selection. In this case, the speed control comes from the setting
in [TB Man Ref Sel], and is limited to terminal block sources.
By default, only the speed reference (not Start or Jog control) changes when
toggling between Auto and Manual. However, it is possible for both Speed
Reference and Start/Jog control to change when toggling between Auto and
Manual.
Refer to the appropriate parameter description for your drive and the tables that
follow for detailed operation.
