d: Reference Settings

The drive offers various ways of entering the frequency reference. The figure below gives an overview of the reference input,
selections, and priorities.

n d1-01 to d1-08, d1-17: Frequency Reference 1 to 8 and Jog Reference
Up to 9 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 8.
Multi-speed reference 1 can be provided by analog input A1.

<1> The upper limit is determined by the maximum output frequency (E1-04) and upper limit for the frequency reference (d2-01).
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-oo = 3, 4, 5). For the Jog reference a digital input must be set to H1-oo = 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.
The different speed references can be selected as shown in
