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, and 3 (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.
• 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 Tabl e 5.14. Figure 5.30 illustrates the multi-step speed
selection.
