Extended brake control
Description
The "Extended brake control" function module allows complex braking control for motor
holding brakes and holding brakes for example.
The brake is controlled as follows (the sequence reflects the priority):
● Via parameter p1215
● Via binector parameters p1219[0..3] and p0855
● Via zero speed detection
● Via a connector interconnection threshold value
Commissioning
The "Extended brake control" function module can be activated by running the
commissioning wizard. Parameter r0108.14 indicates whether the function module has been
activated.
Parameter p1215 must be set to "3" and the brake controlled via a digital output (for example
at the customer terminal block TM31).
Extended brake control when braking with feedback
When braking with a feedback signal (p1275.5 = 1), the brake control reacts to the feedback
signal contacts of the brake. If the timer p1216 is greater than the time to the feedback
signal, then the approach is delayed by the corresponding time difference.
In order to be able to approach with as little delay as possible, the opening time set in p1216
must be shorter than the time to the feedback signal. However, if the timer in p1216 is set
shorter, then alarm A07931 "Brake does not open" appears.
Remedy:
1. Activate the "Release with feedback signal" (p1275.6 = 1).
The pulse enable (BO: r1229.3) and setpoint enable (BO: r0899.15) are now independent
of the set timer (p1217, p1216). The associated enable is determined only by the
feedback signal (BI: p1222, BI: p1223). The timers (p1216, p1217) only affect the
warnings A07931 "Brake does not open" and A07932 "Brake does not close".
2. Optional: To make the two warnings stop appearing, set both timers (p1217, p1216) to 0
ms.
Result: The monitoring of the brake and the display of the alarms are switched off.
