Non motion control configurations
In non motion control configurations (Parameter
Configuration
30 ≠ x40), object
is fixed to “2”
velocity mode. Object
is always “2”
velocity mode. This cannot be changed.

Behavior in quick stop
In quick stop, the parameters
Switch-off threshold
637 (percent of fmax) and
Hold-
ing time
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. The emergency
Emergency
stop clockwise
424 and
Emergency stop anti-clockwise
425.
If frequency/speed zero has been reached during the holding time, the drive contin-
ues 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.
“Behavior in quick stop” is only relevant for non motion control configurations (p.30 ≠
x40).
