Instead of using a speed adjust potentiometer, the drive may be
wired to follow an analog input voltage signal (0 – 3.5 VDC) that
is isolated from earth ground (Figure 4). Connect the signal input
(+) to terminal 4. Connect the signal common (–) to terminal 3.
Make no connection to 5.
If the maximum signal is greater than 3.5V, use the speed adjust
pot as a trimmer. See Figure 5 for connections. With the signal at
maximum, use the speed adjust pot to set the motor to the desired
maximum speed. It is advised that the speed adjust pot be
secured to preclude inadvertent tampering with this important
setting.
