Start/stop

Actuation 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 bypass
contactor off and, with a delay (of 0.5 to 1.0 s), activate the
K3M motor contactor.
• Then, switch the K1M mains contactor on and, at the same
time, activate the digital input configured as CS.
• When the CS input is deactivated, the waiting time set under
PNU b003 begins.
• Once this time has expired, the DF6 frequency inverter
synchronizes to the motor speed and continues to run the
motor.

Here, set a time which is to expire before an automatic
restart is initiated after the supply voltage is connected. This
time can also be used in conjunction with the FRS function.
During the delay, the following message appears on the LED
