The appropriate value for P-0-0545 can be determined on the basis of the
value displayed in
•
P-0-0546, Starting torque for releasing motor holding brake
.
Note:
The value of P-0-0546 should be provided with a safety factor
if used for P-0-0545!
See also respective Parameter Description.
Check for sufficient holding torque of the brake:
The holding torque of the brake is checked by the motor generating a
torque or force with the brake having been applied. The maximum value
can be preset in parameter
•
P-0-0547, Test torque with holding brake applied
.
The criterion for which the check is to be carried out is decisive for
determining an appropriate value for P-0-0547:
•
nominal torque or force of the holding brake
•
holding torque or force for fixing the axis
•
increased holding torque or force.
The nominal torque or force of the holding brake from
P-0-0540, Torque
of motor holding brake
can be activated for the check.
See Parameter Description "P-0-0547, Test torque with holding
brake applied"
The torque or force required for fixing the axis can be determined on the
basis of P-0-0546. In this case P-0-0547 could also be written with the
value of P-0-0545 (safety factor >1 * P-0-0546).
Note:
Due to dimensioning, the required torque or force with the
criterion "fixing the axis" is lower than the nominal torque or
force of the holding brake. This expands the tolerance range
for detection of holding brake wear and therefore increases
the service life of the holding brake.
With safety-relevant dimensioning of the drive it is sometimes necessary
to make increased demands on the holding brake. In this case enter the
respective test torque or force in parameter P-0-0547!
Note:
With the criterion "increased holding torque or force", the
tolerance range for detection of holding brake wear is reduced
which can shorten the service life of the holding brake.
By starting a command it is possible to reestablish, by removing the oxide
film (abrasion of the brake), the holding torque or the holding force of a
holding brake that has not yet become worn.
