Analog Input Gain 1 (AUI1)
Control Mode VF VFPG SVC FOCPG FOCPM Default: 100.0
Settings 0.0–500.0%
Reserved

Analog Input Gain 1 (AUI2)
Control Mode VF VFPG SVC FOCPG FOCPM Default: 100.0
Settings 0.0–500.0%
 Pr.03-03–Pr.03-11 are used when the Frequency command source is the analog voltage/current signal.

Analog Input Filter Time (AUI2)
Control Mode VF VFPG SVC FOCPG FOCPM Default: 0.01
Settings 0.00–2.00 sec.
 Analog signals, such as those entering AUI1 and AUI2, are commonly affected by interference that affects
the stability of the analog control. Use the Input Noise Filter to create a more stable system.
 If Pr.03-14 is large, the control is more stable, but the response to the input is slower. If Pr.03-14 is small,
the control may be unstable, but the response to the input is faster.
Load Compensation Auto-tuning
Control Mode VF VFPG SVC FOCPG FOCPM Default: 0
Settings 0: No function
1: Auto-tunes with running without load
2: Auto-tunes with running with load
 Use torque compensation function to avoid the roll-back generated by using IM to work with spiral gear.
