01/02 AWB8230-1413GB Start/stopActuation of the contactors consists of the following steps:• The startup takes place through the K2M bypass contactor.• Once the motor has accelerated, switch the K2M bypasscontactor off <strong>and</strong>, with a delay (of 0.5 to 1.0 s), activate theK3M motor contactor.• Then, switch the K1M mains contactor on <strong>and</strong>, at the sametime, activate the digital input configured as CS.• When the CS input is deactivated, the waiting time set underPNU b003 begins.• Once this time has expired, the <strong>DF6</strong> frequency invertersynchronizes to the motor speed <strong>and</strong> continues to run themotor.K1MK2MK3MFW0.5 – 1.0 sf 0.5 sCSCSFWD3 FWP24f of 20 msPNU b003Figure 80:Digital input configured FW as FWD (start/stop clockwiseoperation) <strong>and</strong> 3 as CS (heavy mains starting)Figure 81:Function chart for CS (heavy mains starting)X Program one of the digital inputs 1 to 5 as CS by entering thevalue 14 under the corresponding PNU (C001 to C005).PNU Name Adjustable in RUN mode Value Function WENormalExtendedb003Waiting timebefore restart– j 0.3 to 100 s Here, set a time which is to expire before an automaticrestart is initiated after the supply voltage is connected.
