Setting parameters04/07 AWB8230-1541GBOptionally, you can configure the digital inputs as break (NC)contacts. To do this, enter 01 under PNU C011 to C015(corresponding to digital inputs 1 to 5. An exception applies onlyto inputs configured as RST (reset) or PTC (PTC thermistor input).These inputs can be operated only as make (NO) contacts.FWDFRS4 3P24h Attention!If you reconfigure digital inputs set up as FWD or REV asbreak contacts (the default setting is as a make contact),the motor starts immediately. They should not bereconfigured as break contacts if no motor is connected.Figure 79:Configuration of digital input 3 as “controller inhibit”FRS (free run stop) and 4 as FWD (start/stop clockwiserotation)Table 23:PNUConfiguring digital inputs as break contactsTerminalValueC011C0121200 or01C013 3C014 4C015 5RUN Function DS– 00: High signal causesswitch or activation ofthe function (NO =normally open).01: Low signal causesswitching oractivation of thefunction (NC =normally closed).Controller inhibit and coasting (free run stop – FRS)If you activate the digital input configured as FRS, the motor isswitched off and coasts to a stop (for example if an Emergency-Stop is made). If you deactivate the FRS input, then, depending onthe inverter’s configuration, the frequency output is eithersynchronized to the current speed of the coasting motor or restartsat 0 Hz.00FWD/REVFRSn MacFigure 80: Function chart for FRS (control inhibit and free runstop)NM: Motor speedt w : Waiting time (set with PNU b003)a Motor coasts to a stop.b Synchronization to the current motor speedc Restart from 0 HzX Use PNU b088 to specify whether the motor is to restart at 0 Hzafter the FRS input has been deactivated, or if synchronizationto the current motor speed should take place after a waitingtime specified under PNU b003.X Configure one of the digital inputs 1 to 5 as FRS by entering thevalue 11 under the corresponding PNU (C001 to C005).bt wPNU Designation RUN b031= 10Value Function DSb003b088POWER,waiting timebeforeautomaticrestart afterpower supplyfailureMotor restartafter removalof the FRSsignal– j 0.3…100 ss Here, set a time which is to expire before an automatic restart isinitiated after a fault signal.
