Can we use PID function and Preset Speeds with the Altivar Process Drives?

Issue:
Can the Altivar Process Drive be programmed to use Preset Speed when also using PID Control?

Product line:
Altivar Process, ATV630, ATV930

Environment:
all

Cause:
Preset does not have priority over the PID function on Channel 1.

Resolution:
The PID loop won't acknowledge a preset speed on the same channel.  Use a Digital input programmed for PID Auto/Manual to take it out of PID.  Then you can turn on a preset speed.
You can set the same Digital Input to both functions if his Access Level is set to Expert.
