7.6.6.15 External error
183 External Error
Parameterization of an external error enables switching off or shutting down several frequency invert-
ers at a time if a fault occurs in the plant or the drive. If an error occurs in a frequency inverter, the
error signal can be transmitted via a bus system and the required reaction can be triggered in another
frequency inverter. The logic signal or digital input signal which is to trigger the external error can be
assigned to parameter
External Error 183.
Via parameter
Op. Mode ext. Error 535, the response to an external error can be configured. See
chapter 7.4.5 "External error".
No response to external errors. Factory setting.
1 - Error-Switch-Off
The drive is switched off and the error message „F1454 External Error“ is
output if the logic signal or digital input signal for parameter External
2 - Shutdown, Error
The drive is stopped at the current deceleration ramp and the error mes-
sage „F1454 External Error“ is output if the logic signal or digital input
signal for parameter External Error 183 is present.
3 -
Emergency-Stop,
Error
The drive is stopped at the set emergency stop ramp and the error mes-
sage „F1454 External Error“ is output if the logic signal or digital input
signal for parameter External Error 183 is present.
For setting up external warnings parameters
User Warning 1 1363 and User Warning 2 1364 can be
used. Check chapter 7.6.5.9 “Warning mask, application” for further details.
7.6.6.16 PLC
Logic functions and analog functions with functional block programming
With the PLC-functions (table of functions and graphic functional block programming), external analog
or digital signals and internal logic signals of the frequency inverter can be linked to one another.
Apart from standard AND, OR and XOR combinations, various complex logic functions and analog
functions are available. The corresponding output value can be used for other logic instructions and
digital outputs. Logic instructions can be combined to one another so that complex links can be real-
ized. Analog values can be processed and output via analog outputs.
The instructions enable flexible adjustment for linking different input signals.
Analog functions include, for example, comparisons of analog input values, mathematical functions,
PID control functions, filters, limitations, switches and counters.
Example:
A drive is to start if
− enable is given AND IN4D is set
OR
− enable is given AND IN5D and MFI1D are set.
Refer to application manual "PLC".
7.6.6.17 Multiplexer/demultiplexer
The multiplexer/demultiplexer enables the transfer of various digital signals between an overriding
controller and frequency inverters via field bus or between frequency inverters via the system bus.
Multiplexer:
1252 Mux Inputs
The multiplexer features 16 inputs for logic signals or digital input signals.
