5.4.4 Fault indication TRIP
A fault is indicated via the permanently assigned digital output terminal
41 and - in factory setting - via the relay output. If you need the output
terminal 41 with reverse polarity, you have to use a freely assignable
output and set the polarity as required. Before, the relay output must
be assigned to another function.
5.4.5 Ready, RDY
The status "ready" is indicated approximately 0.5 seconds after
mains connection by the illuminated green LED on the keypad and
via the digital output terminal 44.
If you need the permanently assigned output terminal 44 with
inverted polarity you must use a freely assignable output and set
the polarity as required.
In case of a warning (see page 119) the signal "ready" is cancelled
without the inverter being inhibited.
5.4.6 Pulse inhibit, IMP
The status of "pulse inhibit" is indicated by the illuminated yellow
LED on the keypad and the permanently assigned digital output
terminal 45. Pulse inhibit means that the output of the frequency
inverter is inhibited. Possible causes are:
•
Controller inhibit
•
Fault indication TRIP
•
Under-/Overvoltage (see page 119)
If you need the permanently assigned output terminal 45 with
inverted polarity you must use a freely assignable output and set
the polarity as required.
5.4.7 Feedback = Set-value
In configurations with PI controller, the assigned output indicates
that the set speed of the drive has been reached. If you want the
output to switch even before reaching the set-value, enter a range
under C240 where you want the function to be active.The
thresholds are the set-value which is reduced and increased by the
entered value.
Code Parameter Meaning Acceptance
C240 0.5%
0.0...100% Window "Feedback = set-value" ON-LINE
In open-loop control the signal "set-value reached" is transferred to
the output "feedback = set-value ".
5.4.8 Feedback = 0
In configurations with PI controller, the assigned output indicates that
the set speed of the drive has been reached (see page 77 ).
