Behavior in the case of transition 5 (disable operation)

The behavior in transition 5 from "Operation enabled" to "Switched On" can be con-
figured via parameter
No.
392 State transition 5
Operation mode
0 - Coast to stop
1 - DC brake
2 - Ramp
Setting 1 "Direct current brake" is only possible with applications with U/f characteris-
tic control (e.g. configuration 110). Other configurations do not support this operation
mode.
If the frequency inverter is operated with a configuration which does not support the
operation mode Direct Current Brake (e.g. configuration 210, field-oriented control),
value "1" cannot be used.
In this case, the operation mode is not offered in the selection menus of the control
unit KP500 and the control software VPlus.
By default,
tions with torque control, the default value is "0 – coast to stop".
If the configuration is changed, the value set for
changed, if necessary.
The behavior in transition 5 is only relevant for configurations without Motion Control

accelerates to its set reference value again and remains in the state "operation ena-

The change of state from "Operation enabled" to "Switched On" is done after the val-
ue has dropped below the set Switch-Off Threshold and the set holding time has
elapsed (equivalent to the behavior in the case of a quick stop). In this context, pa-
rameters

Immediate transition from "Operation enabled" to
