FUNCTIONS

2.11 Advanced Function

2.11.1 Machine Analyzer (Vector Control only)

Machine Analyzer reads and analyzes the torque and speed data when the inverter oscillates the motor at random torque for

about 0.5 to 4s.

This allows measurement of the response frequency characteristic of speed relative to the motor torque of the machine so

that you can grasp the frequency at which the mechanical system has the resonance point.

Choosing the [Machine analyzer] command in the [Advanced (Z

)] menu displays the following screen.

Before starting Machine Analyzer operation, set the oscillation conditions and oscillation mode.

Various buttons, status indications

CAUTION

1. The Machine Analyzer function is available only for the system that can perform PLG vector control (FR-A7AP required).

2. Machine Analyzer will not work in the following cases.

• Inverter running

• When the second motor is selected (Pr. 450 "9999")

• When the control mode is other than the vector control mode (Pr. 800 "0 to 5")

• When Modbus-RTU communication is selected (Pr. 549 = "1")

• When PLC function is valid (Pr. 414 = "1") (NA/EC only)

(Machine Analyzer cannot be executed, when Machine Analyzer display is activated during PLC function. Disable the PLC function,

and then close and open again the Machine Analyzer display or activate the other display once to perform the Machine Analyzer.)

Start

Start the Machine Analyzer.

Stml Condition

Set the oscillation conditions for Machine Analyzer.

Stml Mode

Set the oscillation mode for Machine Analyzer.

Resonance point, Anti-Resonance

point

Used to directly enter and specify the resonance point and Anti-Resonance point when they

cannot be detected automatically.

Y-axis Scale Optimization

Used to change the scale automatically so that the waveform is contained within the screen.
