The drive will usethe frequency reference that was saved when it restarts.Clearing the Saved ValueDepending on which function is used, it is possible to clear the saved frequency reference value by:• Releasing the input programmed for Acceleration hold.• Setting an Up or Down command while no Run command is active.n d4-10: Up/Down Frequency Reference Limit SelectionSelects how the lower frequency limit is set when using the Up/Down function. Refer to Settings 10 and 11: Up/DownFunction on page 75 for details on the Up/Down function in combination with frequency reference limits.No. Parameter Name Setting Range Defaultd4-10 Up/Down Frequency Reference Limit Selection 0, 1 0Setting 0: Lower Limit is Determined by d2-02 or Analog InputThe lower frequency reference limit is determined by the higher value of either parameter d2-02 or an analog input (A1, andA2) that is programmed for “Frequency bias”.Note: For example, if the command to switch the external reference (H1-oo = 2) is used to switch between the Up/Down function and an analoginput as the reference source, the analog value becomes the lower reference limit when the Up/Down command is active. Change d4-10 to1 to make the Up/Down function independent of the analog input value.Setting 1: Lower Limit is Determined by Parameter d2-02Only parameter d2-02 sets the lower frequency reference limit.u d6: Field Weakeningn d6-01: Field Weakening LevelSets the drive output voltage for the Field Weakening function as a percentage of the maximum output voltage. Enabled whena multi-function input is set for Field Weakening (H1-oo = 63).No. Parameter Name Setting Range Defaultd6-01 Field Weakening Level 0 to 100% 80%n d6-02: Field Weakening Frequency LimitSets the lower limit of the frequency range where Field Weakening control is valid. The Field Weakening command is validonly at frequencies above this setting and only when the output frequency matches the frequency reference (speed agree).No. Parameter Name Setting Range Defaultd6-02 Field Weakening Frequency Limit 0.0 to 240.0 Hz 0.0 Hz1.4 d: Reference Settings60 YASKAWA SIEP YAIZ1U 03B YASKAWA AC Drive – Z1000 Programming Manual
