* If using 4 – 20 mA DC signal input, the offset setting in Function No. 9.07 must be increased from “0%” (factory setting) to “20%”. Set
Jumper J1 to the “CUR” position.
Analog Input 2 – Connect the signal input to Terminal “21” and the common to Terminal “22”, as
shown in Figure 35. See settings for Analog Input 2 (Function Nos. 9.05 – 9.09). Set Frequency
Control (Function No. 2.00) to Analog Input 2 (“0003”). For voltage input, set Jumper J1 to the “VOLT”
position and set Analog Input 2 Type (Function No. 9.08) to Analog Voltage or Current ((“0000”) (facto-
ry setting)). For current input, set Jumper J1 to the “CUR” position and set Analog Input 2 Type
(Function No. 9.08) to Analog Volgage or Current ((“0000”) (factory setting)). For PWM input set
Jumper J1 to the “VOLT” position and set Analog Input 2 Type (Function No. 9.08) to PWM (“0001”).
See Table 15 for Analog Input 2 electrical ratings.
If the Analog Input 2 signal is higher than the input signals specified in Table 15, use Trimpot MAX2 to
attenuate it. Apply the maximum signal input and set the drive for full speed output and observe the
display. Rotate Trimpot MAX2 counterclockwise until the drive output frequency begins to drop. Then
rotate Trimpot MAX2 clockwise until the display returns to the maximum output frequency.
