Sensorless Vector Control
Choose Volts/Hz for general purpose applications or
sensorless Voltage Vector control when high torque output at
lows speeds is critical (150% torque at 1 Hz)

Intuitive Digital Operator
From set up to wiring, the SYSDRIVE 3G3MV is designed for
simplicity. Its user-friendly digital operator gives you easy
access to all 179 of the inverter’s user selectable parameters.
Additionally, the parameter copy function allows you to set up
one inverter, save the parameters to the digital operator’s
memory and download them into multiple 3G3MV inverters.
This function can also be used to verify parameters between
the digital operator and an inverter.
4-digit data display shows the drive’s
operating conditions, parameter values
and fault codes. While the default is Hz,
the 3G3MV can be scaled to read out in
engineering units like RPM.
Quick start LEDs simplify monitoring
the inverter’s status
FREF
- frequency reference can be
monitored or set
FOUT
- output frequency can be monitored
IOUT
- output current can be monitored
MNTR
- monitor the status of important
settings such as error logs, input & output
terminal status, and PID characteristics
F/R
- direction of rotation can be selected
or viewed
LO/RE
- operation from digital operator or
set parameters can be selected
PRGM
- all accessible parameters can be
set or monitored
Face-mounted analog dial provides
easy speed control
Operation keys offer simple access
to parameters. Increase or decrease
parameter numbers, set numbers and
multi-function monitor numbers.
