p1223 BI: Motor holding brake, feedback signal, brake open / Brake feedb open
VECTOR (Extended Can be changed: T
brk)
Data type: Unsigned32
P-Group: Functions
Min
-
Description: Sets the signal source for the feedback signal "brake open".
For motor holding brakes with feedback signal, the signal "brake open" can be activated using p1275.5 = 1.
Dependency: Refer to: p1222, p1275
Note: 1 signal: Brake open.
When braking with 1 feedback signal, the inverted feedback signal is connected to the BICO input for the second
feedback signal (p1222).
p1224[0...3] BI: Close motor holding brake at standstill / Brk close standst
VECTOR (Extended Can be changed: T
brk)
Data type: Unsigned32
P-Group: Functions
Min
-
Description: Sets the signal source for close brake at standstill.
Dependency: Refer to: p1275
Note: [0]: Signal, close brake at standstill, inversion via p1275.2
[1]: Signal, close brake at standstill, inversion via p1275.3
[2]: Signal, close brake at standstill
[3]: Signal, close brake at standstill
These four signals form an OR logic operation.
p1225 CI: Standstill detection, threshold value / Standstill thresh
VECTOR (Extended Can be changed: T
brk)
Data type: Unsigned32
P-Group: Functions
Min
-
Description: Sets the signal source "threshold value" for the standstill identification.
Dependency: Refer to: p1226, p1228, r1229
p1226 Threshold for zero speed detection / n_standst n_thresh
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: Functions
Min
0.0 [1/min]
Description: Sets the speed/velocity threshold for the standstill identification.
Acts on the actual value and setpoint monitoring.
When braking with OFF1 or OFF3, when the threshold is fallen below, standstill is identified.
The following applies when the brake control is activated:
When the threshold is fallen below, the brake control is started and the system waits for the brake closing time in
p1217. The pulses are then canceled.
if the brake control is not activated, the following applies:
When the threshold is fallen below, the pulses are cancelled and the drive coasts down.
