Handling of the Objects
16.4.3.2 Behavior in Quick Stop
In this, the parameters
Switch-off Threshold Stop Function
637 (percent of fmax) and
Holding Time
Stop Function 638 (holding time after falling short of the switch-off threshold) are relevant. In a quick
stop, the drive is shut down via the emergency stop ramps (
Emergency Stop Clockwise 424 or
Emergency Stop Antclockwise
425).

If the 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.
Handling of the Objects
16.4.3.3 Behavior in Transition 5
 392 State transition 5
The behavior in transition 5 from "Operation enabled" to "Switched on" can be parameterized.
The behavior is set via Parameter
State transition 5
392.
Parameter Setting
No. Description Min. Max. Factory
Setting
392 State transition 5 0 2 2
Operation Mode Function
0 - Coast to stop
immediate transition from "Operation enabled" to "Ready", free stoppage
of the drive
1 - DC brake
activation of DC brake, with the end of DC braking there is the change
from "Operation enabled" to "Ready"
2 - Ramp
transmission with normal stop ramp, after reaching standstill, there is a
change from "Operation enabled" to "Ready"
Note: 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 of
fered in the selection menus of the Operator
Panel or the VPlus PC-Software.
Note:
The default value for parameter
State transition 5
392 is operation mode "2 – Ramp".
For configurations with torque control, the default value is operation mode "0 – Coast to
stop". If the configuration is changed, the value set for
State transition 5 392
is also
altered, if necessary.
If transition 5 has been triggered with
State transition 5
392 = "1 -
DC brake“, a new control word
is only accepted after the completion of the transition process. The change of state from "Operation
enabled“ to "Ready“ is carried out after the expiry of the time
Braking time 632 parameterized for
the DC brake.
If parameter
State transition 5
392 = "2 -
Ramp“ has been set, the control word can be set back to
0x0F during the stoppage of the drive. In this method, the drive runs back up to its set reference
value and remains in the state "Operation enabled“.
The change of state from "Operation enabled“ to "Ready“ is carried out after the set switch-off
threshold has been reached and the set holding time has expired (equivalent to the behavior
in a
quick stop). In this, the parameters Switch-off Threshold Stop Function 637 (percent of fmax) and
Holding Time Stop Function 638 (holding time after switch-off threshold reached) are relevant.
