5.4.4 Switching off the motor controller via controller enable (DIN5)
The timing diagram shows the behaviour of the motor c ontroller after the controller enable (DIN5) has
been switched off. The drive is decelerated in a controlled manner for all operating modes with the
“Quick stop” parametrised delay. After reaching the rest state or the parametrised monitoring time
Quic k Stop the output stage is blocked ( motor not energised).
