4.6.3 Stop Category 2
Stop Category 2 4- ][Funktion_Stopp_2
The machine receives the operational stop command (disable) and
brakes the drive using the set braking ramp (STOPMODE and ACT-
FAULT parameters set to “1”).
 The drive is braked in a controlled manner as it comes to a stop. If the
speed VEL0 (see timing diagram in the section entitled “Switch on/
switch off behaviour”) drops below the set value, the holding brake is
applied and the inverted rectifier is shut down. In this case, the mains
voltage is maintained.
 If the mains is switched off, not only is a controlled braking procedure
initiated but the mains voltage is galvanically isolated from the holding
brake after a delay, which can be set on the timer.
