Siemens SINAMICS G120 List Manual page 133

Note: The signal via BI: p0858 (unconditionally close holding brake) has a higher priority than via BI: p0855 (unconditionally
open holding brake).
For a 1 signal via BI: p0858, the command "unconditionally close the holding brake" is executed and internally a zero
setpoint is entered.
p0860 BI: Line contactor feedback signal / Line contact feedb
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source for the feedback signal from the line contactor.
Recommendation: When the monitoring is activated (BI: p0860 not equal to r0863.1), then to control the line contactor, signal BO:
r0863.1 of its own drive object should be used.
Dependency: Refer to: p0861, r0863
Refer to: F07300
Notice: The line contactor monitoring is de-activated if the control signal of the particular drive object is set as the signal
source for the feedback signal of the line contactor (BI: p0860 = r0863.1).
Note: The state of the line contactor is monitored depending on signal BO: r0863.1.
When the monitoring is activated (BI: p0860 not equal to r0863.1), fault F07300 is then also output if the contactor is
closed before it is controlled using r0863.1.
p0861 Line contactor monitoring time / LineContact t_mon
Access level: 3
Can be changed: T
Unit group: -
Min
0 [ms]
Description: Sets the monitoring time of the line contactor.
This time starts each time that the line contactor switches (r0863.1). If a feedback signal is not received from the line
contactor within the time, a message is output.
Dependency: Refer to: p0860, r0863
Refer to: F07300
Note: The monitoring function is disabled for the factory setting of p0860.
r0863.0...1 CO/BO: Drive coupling status word/control word / CoupleZSW/STW
Access level: 3
Can be changed: -
Unit group: -
Min
-
Description: Display and BICO output for the status word and control word of the drive coupling.
Bit field: Bit
00
01
Note: For bit 01:
Bit 1 is used to control an external line contactor.
