SIMODRIVE 611 Planning Guide (PJU) – 05.01 Edition
Signaling contacts of the internal line contactor
111–113 NO contact
111–213 NC contact
Ready relay
Term. 72 – 73.1: NO contact – closed for ”ready”
Term. 73.2 – 74: NC contact – open for ”ready”
When switch S1.2 is in the OFF position “ready”, the relay pulls in if the follo-
wing conditions are fulfilled:
S The internal main contactor is CLOSED (terminals NS1–NS2 connected,
terminal 48 enabled)
S Terminal 63, 64 = on
S It is not permissible that there is a fault condition (also not on FD 611A
Standard, or 611D/611U drives)
S FD 611A with standard interface or resolver with the ready setting must be
enabled (terminals 663, 65)
S The NCU must have run up (840D, 810D)
If switch S1.2 is in the ON position, “fault signal”, the relay pulls in if the following
conditions are fulfilled:
S Internal main contactor CLOSED (terminals NS1–NS2 connected, terminal
48 enabled)
S It is not permissible that there is a fault condition (also not on FD 611A
Standard or 611D/611U drives)
S FD 611A with standard interface or resolver with the ready setting must be
enabled (terminals 663, 65)
S The NCU must have run up (840D, 810D)
For a fault condition, the relay drops out.
With the exception of the line supply monitoring, all of the internal monitoring
functions act on all drive modules connected to the drive converter bus and on
the ready signal. The pulses in the I/R module are inhibited when line supply
faults develop.
