Manual SD6
11.2 Direct and indirect brake connection
There are two ways you can connect the motor holding brake to the drive
controller:
•
Directly:
The motor holding brake is connected directly to X5.
•
Indirectly:
The motor holding brake is connected to the drive controller via a
BrakeExtenderModule BX6, a contactor, a solenoid valve, a power box,
etc.
The differences in the connection are described in section 7 Connection.
Indicate in
F93[0] brake connection
which connection is used for your brake.
Note that the calculation will vary depending on the brake connection release
time (t
release
) and the engaging time (t
engage
).
Direct connection
The following applies to a direct connection:
t
release
= F04
t
engage
= F05
Indirect connection
The following applies for t
release
and t
engage
:
Release time of the connected holding brake.
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.
If the holding brake is indirectly connected via a contactor (
F93
), the total
release time t
rel
=
F04
+ 1.2*
F94
.
For STOBER motors the time should be selected so it is greater than t
2
in the
STOBER catalog by a factor of 1.3.
Set time of the connected holding brake.
When enable is deactivated, the power stage still remains in control during the
set time to prevent a gravity-loaded axis from falling down.
If the holding brake is indirectly connected via a contactor (
F93
), the total set
time t
set
=
F05
+ 1.2*
F95
.
For STÖBER motors the set time should be selected so it is greater than t
1
in
the STÖBER catalog by a factor of 1.3.

Information
This parameter is read from and written to the electronic nameplate
of a synchronous servo motor (SSM) with EnDat encoder if
nameplate
B04
is active the first time the drive controller and motor
are connected or when action
B06
is started.
