Select I1 in DRV Group 07. Input current of 0~20mA into the I1 terminal of the terminal
block to set frequency.
IN-01 Freq at 100% :
sets the operating frequency at the maximum current input. The
operating frequency when the value set in IN-26 is 100% is set.
E.g.1) If IN-01 is 40.00 and IN-23~26 is set at the default value, when 20mA is input into
the I1 terminal, the operation is at 40.00Hz.
E.g.2) If IN-26 is 50% and IN-01, 23~26 are set at the initial value, when 20mA is input
into the I1 terminal, the operation is at 30.00Hz.
IN-20 I1 Monitor :
displays the current input into the I1 terminal. This is used for
monitoring the current input at the moment.
IN-22 I1 Filter :
The set time refers to the time it takes the input current which has been
step input to reach about 63% of the I1 value that has been step input in the inverter.
IN-23 I1 Curr x1 ~ IN-26 I1 Perc y2 :
You can set the slope of the output frequency and
offset value against the current as follows.
IN-31 I1 Inverting :
You can turn the direction of the rotation.
IN-32 I1 Qunatizing :
the same as quantizing function of IN-17. See “IN-17 V1
Quantizing” on page 6-3 in detailed user’s manual from website.
