SINAMICS G List Manual, Edition 12.2004
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
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.
