Precautions for Correct Use
Derating of the rated output current of the inverter may be required depending on the nor-
mal/light load mode selection, operating ambient temperature, side-by-side installation, and
carrier frequency settings.
Use the inverter in an appropriate environment according to A-1 Derating on page A-2.
⚫
Simple position control
The simple position control function enables the position control of up to 8 points with a single
Inverter unit.
With the standard pulse train input function, it realizes accurate position control based on the feed-
back of the pulse generator (PG) signal or the encoder’s phase-A/B signal.
It can be combined with control from the open field network to expand the control range of your sys-
tem.
⚫
Programming function
The 3G3MX2-EV2 Series has the buit-in simple sequence function (DriveProgramming), which
enables a stand-alone inverter to perform simple sequence control.
You can create programs easily in flowchart or text language method by using the CX-Drive.
For details, refer to “DriveProgramming User’s Manual (I580)”.
⚫
Sensorless vector control
This Inverter provides the sensorless vector control and the auto-tuning function, which enable it to
output a high starting torque of 200% at 0.5 Hz.
This enables powerful drive control even at low speeds.
In addition, sensorless vector control can be used in conjunction with the torque limit and torque
control functions.
It is applicable to device contact stopper, load breakage protector, and other control applications.
⚫
V/f control with speed feedback
With the standard pulse train input function, this inverter realizes accurate Vf control based on the
feedback of the pulse generator (PG) signal or the encoder’s phase-A/B signal.
The speed feedback capability ensures stable speed control at high accuracy.
⚫
PID control function
The inverter provides PID control that adjusts the feedback value to match the target value.
This is available to the process control such as temperature, pressure, flow rate.
