Note
All of the connected actuators, contactor coils, solenoid valves, holding brakes,
etc. must be provided with overvoltage limiting elements, diodes, varistors, etc.
This is also true for switchgear/inductances controlled by a PLC output.
The NE and monitoring modules have the following display elements (LEDs):
2 LED red
– 5 V voltage level faulted
3 LED green
– external enable signals not present (terminal 63 and/or terminal 64
missing)
4 LED yellow – DC link charged (normal operation)
5 LED red
– line supply fault (single or multi–phase power failure at terminals
U1, V1, W1)
1)
– commutating reactor not available, incorrectly installed
or incorrectly selected
– system fault level of the line supply or transformer too low
6 LED red
– DC link overvoltage
possible causes: Regenerative feedback off, setting–up operation,
line fault, for UI, PW either not operational or too small,
line supply voltage too high, dynamic overload, line filter
inserted between I/R and the commutating reactor

Note:
1) Detection time for line–supply failure, approx. 30 ms
Line–supply failure is detected from a 3-phase voltage < 280 V.
For a 1-phase line–supply failure, a pulse cancellation is initiated for the drive axes
after approx. 1 min. (stored signal). This is valid for
order number 6SN1114

Display element, NE and monitoring module
Effects of the display states:
1 LED red bright:
Pulses are cancelled for the complete drive group
2 LED red bright:
Pulses are cancelled for the complete drive group
4 LED yellow dark:
Pulses are cancelled for the complete drive group
5 LED red bright:
Pulses are only cancelled for the I/R module (regenerative
feedback into the line supply no longer possible.
Axes initially continue to run. Ready relay drops out)
6 LED red bright:
Pulses are cancelled for the complete drive group
