8. GENERAL GAIN ADJUSTMENT

8.3 Manual mode 1 (simple manual adjustment)

If you are not satisfied with the adjustment of auto tuning, you can make simple manual adjustment with three parameters.

8.3.1 Operation of manual mode 1

In this mode, setting the three gains of position control gain 1 (PG1), speed control gain 2 (VG2) and speed integral compensation (VIC) automatically sets the other gains to the optimum values according to these gains.

User setting	GD2


PG1		PG2
VG2		PG2
VG2	Automatic setting	VG1
VIC	Automatic setting	VG1
VIC

Therefore, you can adjust the model adaptive control system in the same image as the general PI control system (position gain, speed gain, speed integral time constant). Here, the position gain corresponds to PG1, the speed gain to VG2 and the speed integral time constant to VIC. When making gain adjustment in this mode, set the load inertia moment ratio (parameter No. 34) correctly.

8.3.2 Adjustment by manual mode 1

POINT

If machine resonance occurs, adaptive vibration suppression control (parameter No. 63) or machine resonance suppression filter (parameter No. 61 62) may be used to suppress machine resonance. (Refer to Section 9.2, 9.3.)
