Waiting time for status monitoring
Every time the brake status changes, the waiting time set in
C02591 is awaited after the
brake opening or brake closing time has elapsed, before the monitoring of the brake
module/status input BRK_bBrakeApplied (if activated via C02583) and the standstill
monitoring function are switched active again.
r During the "Closing the brake" process, a mechanical contact must signal the status
"brake closed" after the waiting time has elapsed.
r During the "Releasing the brake" process, a mechanical contact must signal the status
"brake released" after the waiting time has elapsed.
[9-14] Definition of the waiting time for status monitoring
 Brake status (with bouncing or transient response)
 Active status monitoring
n C02589 : Brake closing time
o C02590 : Brake opening time
p C02591 : Waiting time - status monit.
r The waiting time in C02591 must be
set so that bouncing of a feedback
contact and the transient response of
the brake current monitoring will be
suppressed completely.
r If there is no appropriate feedback
after the waiting time has expired, the
error output BRK_bError is set to TRUE
until the next control attempt.
