Adjustment Of The Frequency Setting Signals "Bias" And "Gain; Adjustment Procedure - Mitsubishi Electric FR-PU07 Instruction Manual

Adjustment of the Frequency Setting Signals "Bias" and "Gain"

2.6 Adjustment of the Frequency Setting Signals "Bias" and "Gain"
The functions vary with the inverter model. (Refer to the inverter instruction manual for details of the
functions.)
2.6.1

Adjustment procedure

There are three ways to adjust the bias and gain of the frequency setting voltage (current).
(1) Adjust only the bias and gain frequencies and not adjust the voltage (current) (Refer to page 47)
(2) Adjust any point by applying a voltage across terminals 2-5 (starting a current across terminals 4-5)
(Refer to page 49)
(3) Adjust any point without a voltage being applied across terminals 2-5 (without a current being applied
across terminals 4-5) (Page 51)
