Issue:
Setup the Hand/Off/Auto on the ATV630/ATV930 Process drives.

Product Line:
Altivar ATV630 ATV930 Process drive

Environment:
All

Cause:
Wants to be able to wire in an HOC or HOA for switching between the hand of auto or hand-off communications.

Resolution:
This programming is done in the Command and Reference menu. (Main Menu -> Complete Settings -> Command and Reference)
Ref Freq 1 and Cmd Channel 1 will apply to the low (deactivated) state of the switching digital input being used.
Ref Freq 2 and Cmd Channel 2 will apply to the high (activated) state of the switching digital input being used.

Example 1  hand off auto with terminal start stop control in both modes.

Ref Freq 1 config = AI1 for hand control or Pot
Control mode= not separate
Freq switch assign= DI3   logic is DI3 = low = hand or  DI3= high= Auto
Ref Freq 2 Config= AI3 for auto control 4-20mA

Example 2 hand-off com

Ref Freq 1 config = AI1 for hand control or Pot
Control mode= I/O Profile
CMD switching = DI3
CMD channel 1= terminal mode
CMD channel 2 = Ethernet
Freq switch assign= DI3
Ref Freq 2 Config= Ethernet
Logic = DI3= low  Pot speed and terminal control or DI3= high Ethernet command and speed reference.
