Voltage or current follower

Instead of using a speed adjust potentiometer, these DC3N

seriesdrivesmaybewiredtofollowanexternalinput

signal (see Figure 8 on page 31 for connections). This input

signal can be in the form of voltage (0-10 VDC) or current

(4-20 mA). Because these drives have built-in isolation, the

input signal can be either grounded or ungrounded. The

signal slide switch SW504 must be set for current or

voltage input, depending on the input signal type (see Slide

switches section on page 33).
