Kinetic back-up
In par. 14-10 Mains Failure a function was set as Kinetic back-up. The Mains Voltage is below the value
set in par. 14-11 Mains Voltage at Mains Fault. The FC is running the motor momentarily
with kinetic energy from the inertia of the load.
Motor check (FC 100/200 only)
In par. 1-80 Function at Stop the function Motor check was selected. A stop command (e.g. Stop
inverse) is active. To ensure, that a Motor is connected to the FC a permanent test current is
applied to the Motor.
Off1
PROFIDrive profile was selected in par. 8-10 Control Word Profile. Via serial communication the
OFF 1 function is activated. The Motor is stopped via the ramp.
Off2
PROFIDrive profile was selected in par. 8-10 Control Word Profile. Via serial communication the
OFF 2 function is activated. The output of the FC is disabled immediately and the motor coasted.
Off3
PROFIDrive profile was selected in par. 8-10 Control Word Profile. Via serial communication the
OFF 3 function is activated. The Motor is stopped via the ramp.
OVC control
Over Voltage Control is activated in par. 2-17 Over-voltage Control. The connected Motor is supplying
the FC with generative energy. The Over Voltage Control is adjusting the U/f ratio, to run
the motor in controlled mode and to prevent the FC from tripping.
PowerUnit Off
Only with drives with installed Option (ext. 24 V supply). The mains supply to the drive is cut off,
but the control card is still supplied with 24 V.
Premagnetise
Pre-magnetisation is selected in par. 1-80 Function at Stop. A stop command (e.g. Stop inverse)
is activated. A suitable constant magnetising current is applied to the Motor.
Protection md
The FC 100/200/300 has detected a critical status (e.g. an over current, over voltage). To avoid
the drive to trip (Alarm) the Protection Mode was activated, which among others reduces the
switching frequency to 4 kHz. If possible, the protection mode ends after approximately 10 s.
Activation of the Protection Mode can be restricted by adjusting the par. 14-26 Trip Delay at
Inverter Fault.
Q-Stop
1. Quick stop inverse was chosen as a function for a digital input (parameter group 5-1*).
The corresponding terminal (e.g. Terminal 27) is not active.
2. The Quick stop function was activated via serial communication.
