INFORMATION
The response and application times are guide values that were determined at maxi-
mum braking torque.
Possible response times of switching elements or controllers were not taken into ac-
count.
INFORMATION
If the permitted braking work per braking W
1
is exceeded during braking or if the per-
mitted total braking work W
insp
is reached, it can no longer be guaranteed that the
brake will be released.
In this case, the fault message 8977 or 8978 is signaled.
INFORMATION
For the current project planning standard for BK and BP brakes of the CMP50
ELVCD and the functional principle of the brakes, refer to the SEW‑EURODRIVE
"Synchronous Servomotors CMP40 – CMP112, CMPZ71 – CMPZ100" catalog.
If you have questions concerning the BP brake project planning, contact
SEW‑EURODRIVE support.
