Comparison with Previous Model
The following describes the changes and additions from the conventional 3G3MX2 Series.
Use this information when replacing the previous model.
The 3G3MX2-V1 Series Inverter has a different color scheme for its Digital Operator keys, as shown
below.
In addition to conventional induction motors, this inverter provides the PM motor mode to be able to
control PM motors, which results in more efficient control than the conventional energy-saving control.
This is combined with the OMRON’s unique auto-tuning function and initial pole position estimation
function that estimates the magnetic pole position of a PM motor during startup to enable its smooth
start.
This control is suitable for applications with reduced torque characteristics such as fans and pumps
(which do not require torque at low speeds).
However, it cannot be used for applications with constant torque characteristics such as general trans-
fer equipment and elevating axes, where the starting torque exceeds 50% of the motor rating.
The following functions are added to the conventional simple position control function for enhancement.
Use these functions according to your application.

Enhancements to Simple Position Control Function
• Restarting Positioning
: Repositions the motor to the target position if it is out of the
range set in the parameter.
• Position Store Selection at Power Off : Stores the current position at power off and resume from the
stored position at the next power-on.
• Preset Position
: Sets the current stop position as a preset position, for
example, after completion of an origin search.
• Creep Speed Moving Amount Adjustment: Adjusts the amount of movement at the creep speed,
although it was fixed to “1
+
1/4 rotations” conventionally.
