Rockwell Automation VSM500 Integrated Drive/Motor - Manual (Page 38)

7-8 Installing and Operating the VSM500 Integrated Drive/Motor, Version 3.0
7.5.1 Wiring the Preset Speed Inputs
Control terminals 8, 9, and 10 select seven preset speeds as shown in table 7.1. Note
that if you select a preset speed that is greater than the maximum speed setting
(based on the rotary switch setting), the unit uses the maximum speed setting value.
Important: Slide switch position 8 defines whether terminals 8, 9, and 10 are used as
presets (default) or to define the unit’s minimum speed (user option).
Refer to section 8.3.8 for information about using terminals 8, 9, and 10 to
select minimum speed.
To use the preset speeds to set the speed reference, wire to terminals 8, 9, and 10 as
shown in figure 7.8.
