List Manual, 09/2017, A5E33842890
Description:
Activates/deactivates the automatic sensing of the switch-in level for the Vdc_max controller. When the sensing
function is deactivated, the activation threshold r1282 for the Vdc_max controller is determined from the
parameterized connection voltage p0210.
Value:
0:
Automatic detection inhibited
1:
Automatic detection enabled
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Description:
Sets the time threshold for the Vdc_min controller (kinetic buffering).
If this value is exceeded a fault is output; the required response can be parameterized.
Prerequisite: p1296 = 1
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Notice:
If a time threshold has been parameterized, the Vdc_max controller should also be activated (p1280 = 3) so that the
drive does not shut down with overvoltage when Vdc_min control is exited (due to the time violation) and in the event
of fault response OFF3. It is also possible to increase the OFF3 ramp-down time p1135.
Description:
Sets the response for the Vdc_min controller (kinetic buffering).
Value:
0:
Buffer Vdc until undervoltage, n<p1297 -> F07405
1:
Buff. Vdc until undervolt., n<p1297 -> F07405, t>p1295 -> F07406
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note:
For p1296 = 1:
The quick stop ramp entered in p1135 must not be equal to zero, to prevent overcurrent shutdown if F07406 is
triggered.
Description:
Sets the speed threshold for the Vdc-min controller (kinetic buffering).
If this value is exceeded a fault is output; the required response can be parameterized .
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note:
Exiting the Vdc_min control before reaching motor standstill prevents the regenerative braking current from
increasing significantly at low speeds, and after a pulse inhibit, means that the motor coasts down.
