When braking with 1 feedback signal, the inverted feedback signal is connected to the BICO input for the second
feedback signal (p1223).
For r1229.5 = 1, OFF/OFF3 are suppressed to prevent the drive accelerating by a load that drives the motor -
whereby OFF2 remains effective.
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).
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.
Description: Sets the signal source "threshold value" for the standstill identification.
Dependency: Refer to: p1226, p1228, r1229
