VLT ® FCM SeriesProgramming200 Rotation direction(ROTATION)Value:✭Only clockwise,(ONLY CLOCKWISE) [0]Both directions,0-132 Hz (132 HZ BOTH DIRECTIONS) [1]Only counterclockwise, 0-132 Hz(132HZ COUNTERCLOCKW.) [2]Function:This parameter guarantees protection againstunwanted reversing.Using Process, closed loop mode (parameter100) parameter 200 must not be changedto Both directions [1].Description of choice:Select the desired direction seen from themotor drive end.Note that if Only clockwise, 0-132 Hz [0] /Onlycounterclockwise, 0-132 Hz [2] is selected, the outputfrequency will be limited to the range f MIN - f MAX .If Both directions, 0-132 Hz [1] is selected, the outputfrequency will be limited to the range ± f MAX (theminimum frequency is of no significance).NB!:This is only possible in Stop Mode (motorstopped on a Stop command). Ramp willbe followed, if no set up change.NB!:If parameter 200, selection of direction, is setfor different values in the 2 setups, and thesetup is changed during operation, the directionchanges without ramping. In such cases trip mayoccur and that may reduce the service life of the powermodule, as well as it may be harmful to the application.Therefore!It is recommended not to set parameter 200 fordifferent values in the 2 setups. If that should benecessary the user must make sure that setupchanges are only made with stopped motor.201 Min. output frequency(MIN OUTPUT FREQ)Value:0.0 HZ - f MAX (PARAMETER 202) [0 -]✭0.0 HZ [0]Function:In this parameter, a minimum motor frequency limitcan be selected that corresponds to the minimumfrequency at which the motor is to run.The minimum frequency can never be higher thanthe maximum frequency, f MAX .If Both directions has been selected in parameter 200,the minimum frequency is of no significance.Description of choice:A value from 0.0 Hz to the max. frequency selectedin parameter 202 (f MAX ) can be chosen.202 Max. output frequency(MAX OUTPUT FREQ)Value:f MIN (parameter 201) - f RANGE (132 Hz, par. 200)✭f RANGEFunction:In this parameter, a maximum motor frequencycan be selected that corresponds to the highestfrequency at which the motor is to run.See also parameter 205.Description of choice:A value from f MIN to 132 Hz can be selected.203 Reference/feedback range(REF/FEEDB. RANGE)Value:✭Min - Max (MIN - MAX) [0]- Max - + Max (-MAX-+MAX) [1]Function:This parameter decides whether the reference signal isto be positive or can be both positive and negative.NB!:Analogue input (reference/feedback) canonly be positive.Choose Min - Max [0] if Process, closed loop modehas been selected in parameter 100.Description of choice:Choose the desired range.✭ = factory setting.
