Bias And Gain Of Speed Setting Voltage (Current) (Pr. 125, Pr. 126, Pr. 241, C2 (Pr. 902) To C7 (Pr. 905)) - Mitsubishi Electric FR-D720-0.2K-G Instruction Manual

Speed setting by analog input (terminal 2, 4)
4.14.4 Bias and gain of speed setting voltage (current)
(Pr. 125, Pr. 126, Pr. 241, C2 (Pr. 902) to C7 (Pr. 905))
You can set the magnitude (slope) of the rotation speed as desired in relation to the speed setting signal (0 to 5VDC, 0
to 10VDC or 4 to 20mADC).
Set Pr. 267 and voltage/current input switch to switch among 0 to 5VDC, 0 to 10VDC, and 0 to 20mADC input using
terminal 4. (Refer to page 147.)

The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 161.)

The parameter number in parentheses is the one for use with the parameter unit (FR-PU07).

This parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.

The value left of the slash is for the 2.2K drive unit or lower. The one right of the slash is for the 3.7K drive unit.

If a value exceeding the upper speed limit of the motor is set, the actual operation will be limited at the maximum rotation speed. The setting range is for the
S-PM motor. The maximum setting value differs depending on the number of poles of the applied motor.
