Parameterizing the digital outputs

In order to signal to the safety relay that the drive E-STOP function has been activated, the
following parameters must be set at the SINAMICS DC MASTER:
Digital output DO3 at connector X177.22 controls relay K
contact for the E-STOP path.
The function of DO3 (connector X177.22) is defined using parameter p50774:
p50774 = (63) r53100.0
Digital output DO2 at connector X177.21 controls, via relay K
The function of DO2 (connector X177.21) is defined using parameter p50773.
The setting of p50773 is dependent on the setting of parameter p50082:
p50082 = 0
p50082 = 1
p50082 = 2
p50082 = 3
p50082 = 4
p50082 = 21 (external field power unit, otherwise, as for setting
p50082 = 22 (external field power unit, otherwise, as for setting
p50082 = 23 (external field power unit, otherwise, as for setting
p50082 = 24 (external field power unit, otherwise, as for setting
Note
(63) signifies: "from own drive object"
r53100.0 is E-Stop state (1 = no E-Stop, 0 = E-Stop)
r53082.0 is CLOSE armature contactor
r53210.2 is auxiliaries ON
Note
The maximum 100 mA current rating of the digital outputs must be carefully observed.
