Parameters 247
75.05 Start speed 1 Defines the start speed for auxiliary pump 1.
When the speed of the pump connected directly to the drive
exceeds this value and no auxiliary pumps are running, the
start delay counter (see parameter 75.19 Start delay) is
started. If the speed is still at the same level or higher when
the delay elapses, the first auxiliary pump starts.
The running speed of the drive is decreased by Start speed 1
- Stop speed 1 after the auxiliary pump starts.
