Functional Description
CG Drives & Automation, 01-5326-01r3b
Upper Band [397]
If the speed of the master drive comes into the upper band,
an additional drive will be added after a delay time that is set
in “Start delay [399]”.
Communication information
Example:
Max Speed = 1500 rpm
Min Speed = 300 rpm
Upper Band = 10%
Start delay will be activated:
Range = Max Speed to Min Speed = 1500–300 = 1200 rpm
10% of 1200 rpm = 120 rpm
Start level = 1500–120 = 1380 rpm
Fig. 99 Upper band
Lower Band [398]
If the speed of the master drive comes into the lower band
an additional drive will be stopped after a delay time. This
delay time is set in the parameter “Stop Delay [39A]”.
Communication information
Example:
Max Speed = 1500 rpm
Min Speed = 300 rpm
Lower Band = 10%
Stop delay will be activated:
Range = Max Speed - Min Speed = 1500–300 = 1200 rpm
10% of 1200 rpm = 120 rpm
Start level = 300 + 120 = 420 rpm

Start Delay [399]
This delay time must have elapsed before the next pump is
started. A delay time prevents the nervous switching of
pumps.
