In this, the parameters
638 (holding time after falling short of the switch-off threshold) are relevant. In a
quick stop, the drive is shutdown via the emergency stop ramps (

If frequency/speed zero has been reached during the holding time, the drive
continues to be supplied with direct current until the switch-off time has expired. With
this measure, there is an assurance that the drive is stationary in a change of state.
9.2.2
The behavior in transition 5 from "Operation enabled" to "Switched on" can be
parameterized. The behavior is set via parameter
No.

Description
Operation mode
0 -Coast to stop
1 -DC brake
2 -Ramp
Setting operation mode "1 - DC brake" is only possible in applications with
v/f characteristic (e.g. configuration 110), as other applications do not
know such an operation mode.
If the frequency inverter is operated with a configuration which does not
know the DC braking operation mode (e.g. configuration 210, field-
orientation speed controlled), value "1" cannot be set. It is also not
offered in the selection menus of the KP500 control unit or the VPlus
program.
