Brake management works with the following state machine:
Fig. 7-5: Brake management state machine
The time
B311
of brake management begins running at the time of activation. After the time has expired, a
transition is made to the brake test required state. This state is indicated on the inverter display with message
72:brake test
. After you perform a successful brake test in this state, brake management returns to the
no
brake test required
state. And the
B311
cycle begins again.
If the time
B311
expires again in the
brake test required
state without a brake test having been performed at
all or the brake test was not successful, a transition is made to the
brake test mandatory
state takes place.
This state is indicated on the inverter display with fault
72:brake test
. In addition the status is displayed in
parameter
E29 Warning
:
perform brake test
(
1:brake test necessary
). To avoid interrupting a production
process, the malfunction is only generated if there is no enable. The fault must be acknowledged before the
brake test and the brake grinding function can be performed. If the brake test has not been performed
successfully 5 minutes after the acknowledgment, the fault appears again on the inverter display. A successful
brake test in this state automatically takes you back to the no brake test required state and the
B311
cycle
begins again.
If a brake test is not successful in the
brake test mandatory
state, you have the option of grinding the brakes
and trying to perform a brake test again. If this brake test also fails, the brake or the motor must be replaced.
Brake management remains in the
brake test mandatory
state until a successful brake test is performed after
replacement of brake or motor. Time since the last brake test is indicated in parameter
E177 Time passed
since last brake test
. The brake test can be started directly on the inverter, in POSITool or from the higher level
controller.
