Braking Module Dc Link Fast Discharge Delay Time / Bm Dc-Dischg T_Del; Bi: Activating Braking Module Dc Link Fast Discharge; Bo: Braking Module Dc Link Fast Discharge / Bm Dc Link Dischg - Siemens SINAMICS G150 Manual

Warning: Check that binector outputs BO: r3861.n are connected correctly and that the appropriate digital outputs are wired
correctly.
If the interconnection/wiring is incorrect, the software could execute a different (incorrect) function via binector
outputs BO: r3861.n if the Braking Module develops a fault.

Braking Module DC link fast discharge delay time / BM DC-dischg t_del

B_INF (Brk Mod ext) Can be changed: C1(3), T
Data type: Unsigned32
P-Group: Communications
Not for motor type: -
Min
500 [ms]
Description: Sets the delay time for switching in the DC link fast discharge.
Dependency: Refer to: p3863, r3864
Note: The DC link fast discharge is only possible for "booksize" formats. This function is not supported for "chassis"
formats.
p3863 BI: Activating Braking Module DC link fast discharge / BM DC-dischg act
B_INF (Brk Mod ext) Can be changed: T
Data type: Unsigned32 / Binary
P-Group: -
Not for motor type: -
Min
-
Description: Sets the signal source to activate the DC link fast discharge.
The DC link fast discharge is started later with delay time (p3862) when the following conditions apply:
- BI: p3863 = 1 signal.
- an external line contactor is opened via r0863.1 "energize contactor".
The DC link fast discharge is interrupted when the following conditions apply:
- BI: p3863 = 0 signal.
- ON command for the infeed.
Recommend.: The DC link fast discharge should be activated if there is an external line contactor and is correctly interconnected
(r0863.1, p0860). If the DC link fast discharge is not activated together with an external line contactor, then faults
could occur when pre-charging (e.g. F30027).
Dependency: Refer to: r3864
Note: The DC link fast discharge is only possible for "booksize" formats. This function is not supported for "chassis"
formats.

Description: Signal to control (energize) terminal X21.2 "DC link fast discharge" on the Braking Module.
This binector output is used as signal source to interconnect to a digital output. The digital output must be connected
to terminal X21.2 of the particular Braking Module.
