FOR ANY INTELLIGENT
AND HIGH EFFICIENT APPLICATION GVX1000
Dynamic torque-vector control system performs high-speed calculation to determine the required motor power for the
load status. Our exclusive technology promises optimal control of voltage and current vectors for maximum output
torque: Miniaturization of minimum level in the class
Compared to the conventional GVX900 series, the volume is reduced to approximately 50%. (single-phase 200V,
0.4kW). Uniform height dimension
All models up to 4.0kW have a uniform height of 130mm, which makes it easy to design panels. Braking resistor connectable to all models
Owing to a built-in braking transistor, an optional braking resistor can be installed to increase the regenerative
braking capacity for conveyance and transportation machines that require large braking power.
THE NEW GENERAL PURPOSE INVERTER SERIES GVX1000, WITH DYNAMIC TORQUE
VECTOR CONTROL, OFFERS INVINCIBLE TECHNICAL SOLUTIONS FOR AN OPTIMUM
MOTOR CONTROL WITH HIGH EFFICENCY PERFORMANGES AND FLEXIBILITY. Reduced motor wow at low speed
Silectron sistemis unique on-Delay compensation
method reduces motor wow at low speed to approxi-
mately half of that of conventional inverters. Built-in inrush-current suppression circuit as standard
The capacity of peripheral devices such as magnetic contactor can be minimized. Low noise
Remarkably reduces influence to devices wsuch as sensors. Equipped with a terminal for connecting dc reactor for harmonics suppression. Minimal motor sound driving with higher carrier frequency setting. Selectable control meter outputs (analog/pulse changeover). 24V power source for transistor output.

The above graph shows an example of torque characteristics when combining
GVX1000 (at dynamic torque-vector control) with Silectron sistemi standard
three-phase motor (8-type series, 4 poles). Continuous operation torque is for
limits of allowable load torque for using the motor within the allowable temperature
range and is not for motor output torque.
The motor output torque is shown by the short-time operation torque. Trip-free operation
The remarkably improved current limiting function
(Automatic deceleration, stall prevention) provides
continuous stable operation even for an impact load.
