No fault message is issued. 0001 On: Enabled. In the event of an intermittent power supply failure orundervoltage, the frequency inverter goes into fault status (E 09).– j 00 16 restart attempts on intermittent supply voltage failure orundervoltage.01 The number of restart attempts is not limited.00External fault signal (EXT)A digital input configured as EXT allows the direct inclusion ofexternal monitoring devices (temperature and vibrationmonitoring, limit switches, etc.).When the digital input configured as EXT is activated, faultmessage E12 is issued and output through the <strong>com</strong>municationinterface (RS 485/Modbus). The fault message remains active evenif the EXT input is deactivated again and must be acknowledgedwith a reset.A reset can be carried out with:• the RST input or• the Stop key.• Alternatively, the supply voltage can be switched off and onagain.FWD/REVEXTn MRSTK14aFigure 129: Function chart for EXT (external fault message)NM: Motor speedK14: Signalling relay contact K11/K14a Motor coasts to a stop.RST5EXT3FWD1P24X Configure one of the digital inputs 1 to 5 as EXT by entering thevalue 12 under the corresponding PNU (C001 to C005).Figure 128:Digital input 1 configured as FWD (start/stopclockwise operation), 3 as EXT (external fault signal) and5 as RST (reset)i Attention!After a reset, the motor restarts immediately if a startsignal (FWD or REV) is active.119
