n d1-01 to d1-17: Frequency Reference 1 to 16 and Jog Reference
Up to 17 preset references (including Jog reference) can be programmed in the drive. The references can be switched during
Run by digital inputs. The acceleration/deceleration to the new reference is performed using the active acceleration/deceleration time.
The Jog frequency must be selected by a separate digital input and has priority over the references 1 to 16.
The multi-speed references 1 and 2 can be provided by analog inputs.

Multi-Step Speed Selection
Depending on how many speeds are used, some digital inputs have to be programmed for Multi-Step Speed Reference 1, 2,
3 and 4 (H1oo = 3, 4, 5, 32). For the Jog reference a digital input must be set to H1oo = 6.
Notes on using analog inputs as multi-speed 1 and 2:
• If the frequency reference source is assigned to analog input A1 (b1-01 = 1), then this input will be used for Frequency
Reference 1 instead of d1-01. If the reference source is assigned to the digital operator (b1-01 = 0), then d1-01 will be used as Frequency Reference 1.
• When the analog input A2 function is set to “Auxiliary Frequency” (H3-10 = 2), then the value input to terminal A2 will be used as the Frequency Reference 2 instead of the value set to parameter d1-02. When H3-10 does not equal 2, then d1-02 becomes the reference for Frequency Reference 2.
The different speed references can be selected as shown in
illustrates the multi-step speed selection.

Unlike frequency reference lower limit (d2-02) which will affect the frequency reference no matter where it is sourced from
(i.e., analog input, preset speed, Jog speed, etc.), the master speed lower limit (d2-03) sets a lower limit that will only affect the analog input (terminals A1 and A2) that is the active master speed frequency.
Set as a percentage of the maximum output frequency.
Note: The lower limits for the Jog frequency, multi-step speed settings, and 2-step speed settings do not change. When lower limits are set to both the frequency reference (d2-02) and the main frequency reference (d2-03), the drive uses the greater of those two values as the lower limit.

d3: Jump Frequency
n d3-01 to d3-04: Jump Frequencies 1, 2, 3, and Jump Frequency Width
In order to avoid continuous operation at a speed that causes resonance in driven machinery, the drive can be programmed with three separate Jump frequencies that will not allow continued operation within specific frequency ranges. If the speed reference falls within a Jump frequency dead band, the drive will clamp the frequency reference just below the dead band and only accelerate past it when the frequency reference rises above the upper end of the dead band.
Setting parameters d3-01 through d3-03 to 0.0 Hz disables the Jump frequency function.

d4: Frequency Hold and Up/Down 2 Function
n d4-01: Frequency Reference Hold Function Selection
This parameter is effective when either of the digital input functions listed below is used.
• Accel/decel ramp hold function (H1oo = A)
• Up/Down function (H1oo = 10 and 11, sets the frequency reference by digital inputs)
• Up/Down 2 function (H1oo = 75/76, adds a bias to the frequency reference using digital inputs)
Parameter d4-01 determines whether the frequency reference or the frequency bias (Up/Down 2) value is saved when the Run command is cleared or the power supply is shut down.
No.
d4-01
Parameter Name
Frequency Reference Hold Function Selection
Setting Range
0 or 1
Default
0
The operation depends on with what function parameter d4-01 is used.
Setting 0: Disabled
• Acceleration Hold
The hold value will be reset to 0 Hz when the Run command is canceled or the drive power is switched off. The active frequency reference will be the value the drive uses when it restarts.
• Up/Down
The frequency reference value will be reset to 0 Hz when the Run command is canceled or the drive power is switched off.
The drive will start from 0 Hz when restarted.
• Up/Down 2
The frequency bias is not saved when the Run command is switched off or 5 s after the Up/Down 2 command has been released. The Up/Down 2 function will start with a bias of 0% when the drive is restarted.
Setting 1: Enabled
• Acceleration Hold
The last hold value will be saved when the Run command or the drive power is switched off. The drive will use the value that was saved as the frequency reference when it restarts. The accel/decel hold input must be enabled the entire time or else the hold value will be cleared.

The bias is reset to 0% when both inputs Up 2 and Down 2 are either on or off. The drive will use the accel/decel time as selected in d4-04 to accelerate or decelerate to the frequency reference value.
n d4-06: Frequency Reference Bias (Up/Down 2)
This parameter is used to save the frequency reference bias value set by the Up/Down 2 function. It is set as a percentage of the maximum output frequency. The function of d4-06 depends on how the Up/Down 2 function is configured.
• This parameter is not normally used when the frequency reference is set by the digital operator. The user can set d4-06 to a certain value that will be applied when the operation is started, but it will be reset when the frequency reference changes
(including multi-step references) or will be disabled when d4-01 = 0 and the Run command is removed.
• When d4-01 = 0 and the frequency reference is set by an analog or pulse input, the value set in d4-06 is generally added to or subtracted from the frequency reference.
• When d4-01 = 1 and the frequency reference is set by a different source than the digital operator, the bias value adjusted with the Up/Down 2 inputs is stored in d4-06 when 5 s have passed after the Up 2 or Down 2 command release.

This parameter is for handling changes in the frequency reference while the terminal set for Up 2 or Down 2 is enabled. If the frequency reference changes for more than the level set to d4-07, then the bias value will be held, and the drive will accelerate or decelerate following the frequency reference. When the frequency reference is reached, the bias hold is released and the bias follows the Up/Down 2 input commands.

Note: When the frequency reference is set by the digital operator (b1-01 = 0) and d4-01 = 1, the bias value will be added to the frequency reference if no Up/Down 2 command is received for 5 s, and will be reset to 0 afterwards. From that point the bias can be increased up to the limit set in d4-08 again.

Parameter d4-08 sets the lower limit of the Up/Down 2 bias (monitor U6-20) and the value that can be saved in parameter d4-06. Set this parameter to an appropriate value before using the Up/Down 2 function.
Note: When the frequency reference is set by the digital operator (b1-01 = 0) and d4-01 = 1, the bias value will be added to the frequency reference if no Up/Down 2 command is received for 5 s, and will be reset to 0 afterwards. If the bias is increased using the Up 2 command, once it is added to the frequency reference the speed cannot be reduced with a Down 2 command if the limit set in d4-09 is 0. In this case make sure to set a negative lower limit in d4-09 to allow speed reduction.

for details on the Up/Down function in combination with frequency reference limits.
Setting 0: Lower Limit is Determined by d2-02 or Analog Input
The lower frequency reference limit is determined by the higher value of both, parameter d2-02 or an analog input that is programmed for “Frequency Bias” (H3-02/10 = 0).
Note: If the external reference change over function (H1oo = 2) used to switch between Up/Down function and analog input as reference source, the analog value would become the lower reference limit when the Up/Down reference is active. Change d4-10 to 1 to make the Up/Down function independent of the analog input value.
Setting 1: Lower Limit is Determined by Parameter d2-02
Only parameter d2-02 sets the lower frequency reference limit.
