19-13 Brake wear limit
Range:
0
Function:
Disabled
When the automatic brake control function is disabled, the drive
controls the application also at standstill.
Enabled
When the automatic brake control function is enabled, the elec-
tromechanical brake is automatically activated every time the
application has been at standstill for a time period specified in
parameter 19-12. This is especially useful in hoist applications
where the motor could overheat if it has to deliver full torque at
standstill for a prolonged period of time.
Function:
Used in conjunction with the automatic brake control function.
The coast delay is the delay after activating the electro-me-
chanical brake before disabling the controller and coasting the
drive. Useful in hoisting applications where the load would oth-
erwise have a tendency to drop a little after each stop because
the activation of the brake is slower than the deactivation of the
drive.
Function:
Used in conjunction with the automatic brake control function.
The brake delay is the delay after activating the control and
magnetising the motor before the brake is deactivated. Useful
in applications with (typically large) motors that take a longer
time to be fully magnetised than the time it takes for the electro-
mechanical brake to deactivate.
Function:
[0...10,000 s]
Used in conjunction with the automatic brake control function.
The hold delay is a waiting period in which the brake is not ac-
tivated even though the application is at standstill. Useful in
applications where a sequence of fast positioning commands is
followed by longer standstill periods.
Function:
[0 ( = disabled) ...
Setting a value higher than "0" (disabled) the drive defines an
1,073,741,824 UU]
error situation ("Brake wear limit exceeded" – ERROR STATUS
= 7) if the drive moves more than the number of UU specified
in this parameter while the electronic brake is activated.
