1. FUNCTIONS AND CONFIGURATION 1.1 Summary The Mitsubishi AC servo amplifier MELSERVO-J3W series is an AC servo that requires less space, less wiring, and less energy while it maintains high performance, functionality and usability of MELSERVO-J3-B. Two servo motors can be driven by this MR-J3W servo amplifier. Driving two servo motors by one MR-J3W servo amplifier cuts down the installation area compared to the area required for two MR-J3 servo amplifiers.

Page 118 6. GENERAL GAIN ADJUSTMENT 6. GENERAL GAIN ADJUSTMENT POINT Consider differences among machines, and adjust the gain. It is recommended that the amount of torque generated from the servo motor in operation be set to 90 the maximum torque of the servo motor. The torque loop mode does not require the gain adjustment.

Page 120 6. GENERAL GAIN ADJUSTMENT 6.2 Auto tuning 6.2.1 Auto tuning mode The servo amplifier has a real-time auto tuning function which estimates the machine characteristic (load inertia moment ratio) in real time and automatically sets the optimum gains according to that value.

Page 122 6. GENERAL GAIN ADJUSTMENT 6.2.3 Adjustment procedure by auto tuning Since auto tuning is made valid before shipment from the factory, simply running the servo motor automatically sets the optimum gains that match the machine. Merely changing the response level setting value as required completes the adjustment.
Page 123 6. GENERAL GAIN ADJUSTMENT 6.2.4 Response level setting in auto tuning mode Set the response (The first digit of parameter No.PA09) of the whole servo system. As the response level setting is increased, the track ability and settling time for a command decreases, but a too high response level will generate vibration.
Page 124 6. GENERAL GAIN ADJUSTMENT 6.3 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. POINT If machine resonance occurs, machine resonance suppression filter (parameter No.PB01, PB13 to PB16) may be used to suppress machine resonance.

SPECIAL ADJUSTMENT FUNCTIONS 7.4 Low-pass filter (1) Function When a ball screw or the like is used, resonance of high frequency may occur as the response level of the servo system is increased. To prevent this, the low-pass filter is factory-set to be valid for a torque command. The filter frequency of this low-pass filter is automatically adjusted to the value in the following expression.
