1.1.4 DefinitionsFrequency converter:IVLT,MAXMaximum output current.IVLT,NRated output current supplied by the frequency converter.UVLT, MAXMaximum output voltage.Input:Control commandStart and stop the connected motor by means of LCP anddigital inputs.Functions are divided into two groups.Functions in group 1 have higher priority than functions ingroup 2.Group 1 Reset, Coasting stop, Reset and Coasting stop,Quick-stop, DC braking, Stop and the [OFF] key.Group 2 Start, Pulse start, Reversing, Start reversing, Jog andFreeze outputMotor:Motor RunningTorque generated on output shaft and speed from zero rpmto max. speed on motor.fJOGMotor frequency when the jog function is activated (viadigital terminals).fMMotor frequency.fMAXMaximum motor frequency.fMINMinimum motor frequency.fM,NRated motor frequency (nameplate data).IMMotor current (actual).IM,NRated motor current (nameplate data).nM,NRated motor speed (nameplate data).nsSynchronous motor speedns = 2 ×par. 1 − 23 × 60spar. 1 − 39PM,NRated motor power (nameplate data in kW or HP).TM,NRated torque (motor).UMInstantaneous motor voltage.UM,NRated motor voltage (nameplate data).Break-away torque175ZA078.10Pull-outrpmTorqueηVLTThe efficiency of the frequency converter is defined as theratio between the power output and the power input.Start-disable commandA stop command belonging to the group 1 controlcommands - see this group.Stop commandSee Control commands.References:Analog ReferenceA signal transmitted to the analog inputs 53 or 54, can bevoltage or current.Binary ReferenceA signal transmitted to the serial communication port.Preset ReferenceA defined preset reference to be set from -100% to +100% ofthe reference range. Selection of eight preset references viathe digital terminals.Pulse ReferenceA pulse frequency signal transmitted to the digital inputs(terminal 29 or 33).RefMAXDetermines the relationship between the reference input at100% full scale value (typically 10V, 20mA) and the resultingreference. The maximum reference value set in3-03 Maximum Reference.Introduction FC 300 Programming Guide4 MG.33.MB.02 - VLT® is a registered Danfoss trademark11
