Digital outputs

Operating principle
The 3RW55 and 3RW55 Failsafe soft starters have 4 digital outputs (DQ1 = output 13, 14; DQ2 =
output 23, 24; DQ3 = output 95, 96, 98; DQ4 = output 43, 44 or output 41, 42 (F‑RQ)) (Page 71)
with which external actuators such as a brake contactor or indicator lamp can be activated.
Using the output actions, you can assign an output action to the digital outputs. Digital output 3
is permanently assigned to the output action "Group error". The 3RW55 Failsafe soft starter has a
safety signaling output (output 4, F‑RQ) (Page 73). This output cannot be parameterized. The
remaining outputs of the 3RW55 and 3RW55 Failsafe soft starters can be assigned an output
action independently of one another.
