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 22, 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 Table 23, on page 42, for drive programming. See Figure 32, on page 42, for
connections.
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 30, on
page 40, and Figure 31, above.
