Behavior in Transition 5 (Disable Operation)

Operation Mode
Function
0 - Coast to Stop
Immediate transition from "Operation released" to "Switched On", drive
coasts to a standstill.
1 - DC-Brake
Activation of DC brake, at the end of DC deceleration, there is the change
from "Operation released" to "Switched On".
2 - Ramp
Transition at normal ramp, when the drive has come to a standstill, there
is the change from "Operation released" to "Switched On".
Note:
Setting operation mode "1 - DC brake" is only possible in applications with v/f characteristic (e.g. configu-
ration 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 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 time parameterized for the DC brake
Braking time
632 has expired.
If the parameter
State transition 5
392 = "2 - Ramp" has been set, the
controlword can be set back to
"Enable operation" during the stoppage of the drive. In this way, the drive runs back up to its set refer-
ence value and remains in the state "Operation enabled".
The change of state from "Operation enabled" to "Switched On" is carried out after the set switch-off thre-
shold has been reached and the set holding time (equivalent to the behavior in a quick stop) has expired.
In this, the Parameters
Switch-off Threshold Stop Function
637 (Percentage value of Parameter
Maxi-
mum Frequency
419) and
Holding Time Stop Function
638 (holding time after switch-off threshold
reached) are relevant.
