6.2.5 Example: Quick stop
This example illustrates the "quick stop" funcon. If a quick stop is acvated, the motor is
brought to a standsll within the deceleraon me set in 0x291C (P225.00).
•
The switch S1 starts the motor in the forward direcon of rotaon. The switch S1 in the
inial posion stops the motor again.
•
The switch S2 acvates the "quick stop" funcon.
Cancelling the quick stop causes a restart of the motor if the "Run” funcon is
sll acve (switch S1 closed)!

①
If a quick stop is acvated, the motor is decelerated to the frequency setpoint 0 Hz within a short period of me. The "Quick stop acve
[54]" status is set as long as quick stop is acvated. The "Stop acve [53]" status is not set.
②
An acve stop command is interrupted by a quick stop.
③
If quick stop is cancelled again before standsll is reached, stopping is connued with the stop method set in 0x2838:003 (P203.03). In the
example: Stop with standard ramp.
