1. Introduction:
All magneticallyinfluenced switching linkse.g. magneticvalvesorrelaisundergo acertainswitching
delay. Thisdelayconsist ofthe following coefficients:
1. the time, needed to establish the magneticfield,
2. the time, needed to overcome invertia,
3. the time, needed to dismantle the magneticfield when switching off.
Toaccelerate the establishment ofthe magneticfieldand therebyto shorten the switching timeofa
switching linkduring the process off switching on, DIGISPEEDgivesan overload impulseup to
100 Voltonto the switching link'scoil.Bythisover-energizing the magneticfieldinthe coil will be
increased, whichcausesaquickerovercoming ofinvertia. During the process ofswitching of

26VDC and causesa decreasing switching-off time.
Result: Bytime-intervalcontrolled overload-impulsesin connection with the regulationofthe flywheel-
