 Availability of Position Control by the Feedback
The inverter can realize accurate position control by feeding back the load-side position information,
just like a servo system. It is effective to save costs for the whole sysytem because the position con-
trol system with a motor over 15 kW is available, and also other position controllers are unnecessary
if the inverter’s internal position control function is used.
This inverter has the following position control functions.
• Absolute position control mode and high-resolution absolute position control mode that can con-
trol up to 8 points
• Pulse train position control mode that can control via pulse input from the host controller
• Orientation function that controls a rotating shaft to stop at a fixed position
 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 without temperature
controller or external controller.
 Power Interruption Restart Function
If a momentary power interruption occurs during operation, the inverter automatically recognizes the
rotation speed of the motor at power recovery, without detecting undervoltage, to enable a smooth
restart.
 Stall Prevention Function
Induction motors may stall (or step out) if a large load is applied due to rapid acceleration or load
fluctuation.
This inverter has the overload limit function that prevents such a stall condition and ensures a per-
sistent operation.
The 3G3R2 Series Inverter contributes to the reduction of man-hours in all phases of inverter-related
work: from wiring, parameter setting, operation, through to maintenance.
 Removable Color LCD Digital Operator Equipped
This inverter has a removable LCD Digital Operator as standard equipment.
This Color LCD Display is equipped to provide easier view of the monitor for parameter settings.
You can save inverter data to LCD operator and it can be used as a copy unit.
By connecting the optional special cable, it is possible to operate the Digital Operator at hand or
install it to the front face of the control panel. This is convenient during setup or maintenance opera-
tion.
When the optional battery (CR2032, 3V) is set in the LCD operator, date and time can be displayed
in the error history. This display is useful in troubleshooting when an error occurs.
 Safe Torque OFF (STO) Function
Safe Torque OFF (STO) function complying with IEC61800-5-2 is equipped. By a signal from safety
devices like emergency shutoff button, the motor current can be shutoff to stop the motor safely.
