Analog input and output parameter group 02
PARAMETER DESCRIPTION 81
Example 1.2: Set 02-27(P.196) and 02-28(P.197) value, then set 02-25(P.198) and 02-26(P.199). Figure is shown
as follows:
02-25
（P.198）
02-26
（P.199)
02-27
（P.196）
02-28
（P.197）
Terminal 3-5 signal
%
If the external analog frequency is selected, the ratio calculated according to the figure above is multiplied by
02-21 (P.39) to be the actual frequency input value ( terminal 3-5 current/voltage input corresponding percentage
selections are all positive 02-61( P.141) = 0).
Polarity of percentage corresponds to terminal 3-5 current/ voltage signal

The setting of parameter 02-61 (P.141) is set in bits, a total of 2 bits, the meaning of each bit is as follows:
02-61

: Parameter 02-27(P.196) value
is for positive
1: Parameter 02-27(P.196) value
is for negative
0: Parameter 02-28(P.197) value is for positive
1: Parameter 02-28(P.197) value is for negative
If the input percentage of the given current/voltage is negative, the inverter runs in the reverse direction of the given
running direction.

Some application examples of terminal 3-5
Example 1: This example is the most commonly used method. It is used when inverter is in “external mode",
“combined mode 2”or “combined mode 4”, and frequency command is given by terminal 3-5.

Example 2: This example is for users who need the motor to run at 10Hz when the potentiometer is turned to the
left end. All frequencies above 10Hz can still be adjusted by the user freely.
