5.4 d: Reference Settings 5.4 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. b1-01 (Freq.

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. 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- = 3, 4, 5). 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. The different speed references can be selected as shown in Table 5.9 . Figure 5.9 illustrates the multi-step speed selection.
