◆ d1: Frequency Reference
■ 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 Selection 1, 2, 3 and 4 (H1- = 3, 4, 5, 32). For the Jog reference a
digital input must be set to H1- = 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 Multi-Step Speed 2 instead of the value set
to parameter d1-02. When H3-10 does not equal 2, then d1-02 becomes the reference for
Multi-Step Speed 2.
The different speed references can be selected as shown in Table 1.29. Figure 1.32
illustrates the multi-step speed selection.
