ANALOG INPUT "1" AND "2" SIGNAL GAIN AND OFFSET WITH NEGATIVE SLOPE

(HIGH-TO-LOW SIGNAL) (FUNCTION NO. 9.01 OR 9.06 SET TO "0001")

ANALOG INPUT "1"

See Table 14 for Analog Input 1 electrical ratings.

Connect the signal input to Terminal "19" and the common to Terminal "20".
Connect the Start (Jumper) to Terminal "5", which is factory set for N.O. Start
("0010") and to any available common terminal ("8", "12", "14", "16", "18" "20",
"22"). See Figure 22, on page 29, for connections. See Table 15, on page 29,
for drive programming.

MAX1 Trimpot: If the Analog Input 1 signal is higher than 5 Volts, use Trimpot

MAX1 to attenuate it. Apply the maximum signal input and set the drive for full
speed output and observe the display. Rotate Trimpot MAX1 counter clockwise
until the drive output frequency begins to drop. Then, rotate Trimpot MAX1
clockwise until the display returns to the maximum output frequency.

Set the signal Slope and Type and adjust the Gain, Offset, and Response Time
as desired. See Figure 20, on page 27, and Figure 21, above.
