6 -80 Stopping Acceleration and Deceleration (Acceleration/DecelerationRamp Hold)The acceleration/deceleration ramp hold function stops acceleration and deceleration, stores the output fre-quency at that point in time, and then continues operation.Set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selection) toA (acceleration/deceleration ramp hold) to stop acceleration and deceleration when the terminal is turned ONand to store the output frequency at that point in time. Acceleration and deceleration will restart when the ter-minal is turned OFF.If d4-01 is set to 1 and the Acceleration/Deceleration Ramp Hold command is input, the output frequency isstill stored even after the power supply is turned OFF.Related ConstantsTime ChartThe time chart when using Acceleration/Deceleration Ramp Hold commands is given below.Fig 6.50 Acceleration/Deceleration Ramp HoldCon-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-tord4-01Frequencyreferencehold functionselectionSets whether or not frequencieson hold will be recorded.0: Disabled (when operation isstopped or the power isturned on again starts at 0.)1: Enabled (when operation isstopped or the power isturned on again starts at theprevious hold frequency.)This function is available whenthe multi-function inputs “accel/decel Ramp Hold” or “up/down”commands are set.0 or 1 0 No A A A A 298HPower supplyForward/StopAcceleration/DecelerationRamp HoldFrequency referenceOutput frequencyHold Hold
