Frequency Inverter DF51... - Moeller.com.tr

Setting parameters04/07 AWB8230-1541GBStart/Stop signalBy default, the DF51 always decelerates the drive to 0 Hz when theSTOP button on the keypad is pressed or the Enable signal FWD(control signal terminal 1) or REV (control signal terminal 2)switchoff. The deceleration time is set with PNU F003 (default =10 s).hFor further settings and the behaviour of the DF51 after aSTOP signal, see “System settings” (page 135) and “DCbraking (DCB)” (page 121).Start signalBy default the start signal is triggered through the inputsconfigured as FWD (control signal terminal 1) and REV (controlsignal terminal 2).Figure 78:REV2Digital input 2 configured as REV1Under PNU C001 to C005 or C201 to C205 (second parameter set)you can assign the start signal to any digital input: 00 = FWD, 01= REV.P24i Caution!If the supply voltage for the frequency inverter is appliedwhen the start signal is activated, the motor will startimmediately. Make sure that the start signal is not activebefore the supply voltage is switched on.i Caution!Note that, when the FWD/REV input is opened (inactivecondition when it has been configured as a N/O contact)and the input is then reconfigured as N/C contact, themotor may start immediately after the configuration.Clockwise rotating field (FWD)When you activate the digital input configured as FWD (forward)input, the frequency in phase sequence U-V-W is applied at theDF51’s output. If connected accordingly, the motor then starts upin a clockwise direction. When the input is deactivated, the motoris decelerated.FWD1P24Figure 77:Digital input 1 configured as FWDAnticlockwise rotating field (REV)When the digital input configured as REV (reverse) is activated, themotor starts up in an anticlockwise direction (W-V-U). When theinput is deactivated, the motor is decelerated.If you activate the FWD and the REV input at the same time duringoperation, the motor coasts to a halt.78
