Issue:
ATV630 and ATV930 drives PID setup for auto manual with an HOA switch.

Product Line:
Altivar ATV630 and ATV930

Environment:
All

Cause:
Hand= manual control, Auto= PID control with POT as PID setpoint

Resolution:
Program the drive as follows:
[Complete settings] [Pump functions] [PID controller] [Reference frequency]
If Internal PID ref is NO then drive will look at FR1 for the PID setpoint.
FR1 = AI1 speed POT

Auto manual Assignment  PAU choose Digital input example DI3
Manual reference assignment is AI1 speed POT

In Hand: DI3 PAU is going to be high then speed ref is AI1 speed pot.
In Auto: DI3 PAU is going to be Low, speed ref is PID feedback and PID set point is AI1 speed pot.
