Issue:
With an ATV212, is there a auto/ manual configuration to switch between PID reference and a second analog reference?

Product Line:
Altivar 212

Environment:
All

Cause:
Auto/manual switching

Resolution:
[Auto/man speed ref] Auto/Manual Speed Reference Switching 0
0 [Enable]
1  [Disable]
Switching between two speed reference sources by means of a logic input is enabled if parameter F200 is set to 0.
To use this function, you need to assign a logic input to function 38, Auto/Man speed ref.
When the assigned logic input is off, the drive will follow the speed reference source defined by parameter [Frequency mode sel]
(FMOd)
When the assigned logic input is on, the drive will follow the speed reference source defined by parameter [Remote spd ref 2]
(F207)
When parameter F200 is set to 1, the drive will follow the FMOd speed reference source when it is operating above 1 Hz.
Below 1 Hz, it will follow the F207 speed reference source
