7.15.5 Brake control
For applications in the areas lifting and lowering, or other applications requiring the use of a brake, the control
of the brake can be taken over by the KEB frequency inverter.
For this the brake control must be activated in parameter Pn.34 "brake control mode" and a transistor or relay
output must be assigned with the function "18: brake control". The output becomes active if the brake shall
be released.
7.15.5.1 Mode brake control
The status display during brake handling can also be dened with Pn.34 and a monitoring function can be
activated.
The brake control is set-programmable.
Pn.34: Mode brake control
Value Explanation
0: off Brake control deactivated.
1: with display
Brake control activated. Progress message "85: Close brake" (bon) or "86: Open bra-
ke" (boFF).
2: withoutdisplay Brake control activated. No brake-specic status messages.
3: with phase check
/ with display
Brake control activated. Progress message "85: Close brake" (bon) or "86: Open bra-
ke" (boFF). Check whether all 3 inverter output phases can be powered. If one phase
is missing, "56: ERROR! Brake control" (E.br) is triggered.
4: with phase check
/ without display
Brake control activated. No brake-specic status messages. Check whether all 3 in-
verter output phases can be powered. If one phase is missing, "56: ERROR! Brake
control" (E.br) is triggered.
5: quick stop / with
display
Brake control activated. The brake release time immediately starts (Pn.36) if the drive
restarts during brake closing time (Pn.40).
6: quick stop / wit-
hout display
Brake control activated. The brake release time immediately starts (Pn.36) if the drive
restarts during brake closing time (Pn.40). No brake-specic status messages.
7: phase check /
quick stop / with
display
Brake control activated. The brake release time immediately starts (Pn.36) if the drive
restarts during brake closing time (Pn.40). Check whether all 3 inverter output phases
can be powered. If one phase is missing, "56: ERROR! Brake control" (E.br) is trig-
gered.
8: phase check /
quick stop / without
display
Brake control activated. The brake release time immediately starts (Pn.36) if the drive
restarts during brake closing time (Pn.40). No brake-specic status messages. Check
whether all 3 inverter output phases can be powered. If one phase is missing, "56:
ERROR! Brake control" (E.br) is triggered.
