5.4 d: Reference SettingsYASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 201Parameter Details5Figure 5.47 shows the relationship between the Jump frequency and the frequency reference.Figure 5.47Figure 5.47 Jump Frequency OperationNote: 1. The drive will use the active accel/decel time to pass through the specified dead band range, but will not allow continuous operationin that range.2. When setting more than one Jump frequency, make sure that the parameters do not overlap. d4: Frequency Reference Hold and Up/Down 2 Function d4-01: Frequency Reference Hold Function SelectionThis parameter is effective when either of the digital input functions listed below is used.• Accel/decel ramp hold function (H1-= A)• Up/Down function (H1- = 10 and 11)• Up/Down 2 function (H1- = 75 and 76)Parameter d4-01 determines whether the frequency reference or the frequency bias (Up/Down 2) value is saved when theStop command is entered or the power supply is shut down.The operation depends on the function used with parameter d4-01.Setting 0: Disabled• Acceleration holdThe hold value will be reset to 0 Hz when the Stop command is entered or the drive power is switched off. The activefrequency reference will be the value the drive uses when it restarts.• Up/DownThe frequency reference value will be reset to 0 Hz when the Stop command is entered or the drive power is switchedoff. The drive will start from 0 Hz when it is turned back on again.• Up/Down 2The frequency bias is not saved when the Stop command is entered, or 5 s after the Up/Down 2 command has beenreleased. The Up/Down 2 function will start with a bias of 0% when the drive is restarted.<1> In AOLV/PM and CLV/PM control modes, the setting units and range are expressed as a percent (0.0 to 100.0%) instead of in Hz.<2> In AOLV/PM and CLV/PM control modes, the setting units and range are expressed as a percent instead of in Hz. The Setting range is 0.0 to40.0% and the default is 1.0%.No. Parameter Name Setting Range Defaultd4-01 Frequency Reference Hold Function Selection 0 or 1 0FrequencyreferenceOutputFrequencyJumpFrequency3(d3-03)JumpFrequency2(d3-02)JumpFrequency1(d3-01)FrequencyreferencedecreasesFrequencyreferenceincreasesd3-04 d3-04d3-04 d3-04d3-04 d3-04
