9.2.2. Process controller rinse function
This function accelerates the motor in idle state of the process controller at regular
intervals to a defined speed.
Details
A typical application for this function is the rinsing of a pipe system with a pump that has
been in an inactive state for a longer period to prevent deposits.
• In order to activate the rinsing function, set the selection "Enabled [1]" in 0x4024:001
(P615.01).
• The following diagram demonstrates the function:
•
The rinsing function uses the ramp times set for the "MS: Velocity mode".
