Overview of Functions

The Multi-function Compact Inverter 3G3M1 Series is mounted with diverse motor control methods for
bringing out the performance of motors, advanced position control based on PG input, and SIL3/PLe-
compatible STO as part of the standard specifications, and has been designed to expand the potential
of supported applications.

Features of 3G3M1 Series Inverter

Application Support
 Diverse motor control
PM motors up to 128 poles and conventional induction motors are supported which allows a di-
verse range of motors to be driven.
Motor options for implementing on devices have been expanded. This allows the performance of
motors selected in accordance with nine motor control methods to be fully demonstrated. In addi-
tion, an auto-tuning function enables optimum PM motor parameters to be set to ensure smooth
motor startup.
 Position Control
The inverter incorporates an encoder (PG) input function (ABZ phase, 1CH). Input of general en-
coder output as feedback position information enables position control of higher accuracy than that
of previous models to be achieved. Position control suited to individual device applications, such as
I/O input-based position control and Modbus communication-based commands from a host control-
ler, is supported.
 Safety Function
STO functions (SIL3/PLe) are achieved by hard-wiring. Safety inputs on two channels and EDM
output are supported.
FSoE (Safety over EtherCAT) protocol is supported for safe communications. Safe systems can be
built by using the STO functions from a safety controller on the EtherCAT network.
 Conventional functions
Functions such as dual rating, multi-function I/O functions, analog I/O, relay output, PID functions,
Modbus communication, torque control, and restart after momentary power failure are supported,
and the inverter has been designed to achieve the same applications as on previous models.
Sustainability
 Improved device efficiency
Support for PM motors has been expanded. This has become all the more necessary as concern
regarding energy savings has increased. Inverter efficiency has been improved, for example, by
the removal of mechanisms such as speed reduction gears as a result of adopting a multi-pole mo-
tor and by drum motors with built-in conveyor, in addition to the support of high efficiency motors.
