Holding brake
11
Manual SD6
Connection type of the brake.
Switching time (release) of the contactor by which the connected brake is
switched.
When enable is activated, starting of the axis and status signals is delayed
during the release time to prevent driving against a brake that has not been
completely released yet.
Switching times
F94
and
F95
can be determined automatically with the action
if a feedback signal is present and connected.
Switching time (set) of the contactor by which the connected brake is switched.
When enable is deactivated, the power stage still remains in control during the
set time to prevent a gravity-loaded axis from falling down.
Switching times
F94
and
F95
can be determined automatically with the action
if a feedback signal is present and connected.
11.3 Internal and external brake control
In the CiA 402 Controller Based Mode (CBM) application, you have the option
to switch from an internal (automatic) to an external (controller) brake
controller.
Brake controlled internally (Automatic) by the drive controller or externally by a
control unit.
CAUTION!
Unexpected machine response!
During external control the brake does not automatically engage after enable
is turned off and when faults occur.
Make certain there is a suitable process in the control unit. Take suitable
measures to ensure safety.
Relationship between F06 and F92
:
F93
brake connection
version 0
0: direct
The brake is connected directly X5.
Monitoring of a short circuit, open load and
undervoltage of the brake controller takes
place.
1: indirect with feedback
The brake is connected via a contactor at X4.
Monitoring of a short circuit and undervoltage
of the brake controller takes place. Instead of
open load monitoring, a NO contact of a
contactor connected to X6.1/2 is monitored.
2: indirect without feedback
The brake is connected via a contactor at X4.
Monitoring of a short circuit and undervoltage
of the brake controller takes place.
