OPTIDRIVE PLUS 3

GV

3rd Generation Vector Control

AC Variable Speed Drive 0.37-160kW

Optidrive Plus 3GV is the natural evolution of the
Optidrive family adding ultimate motor control to
established Optidrive benchmarks of control and
ease of use.

Optidrive Plus 3
revolutionary and patented motor control strategy.

GV

3

technology delivers 100% torque at 0.0Hz
allowing this unique open loop product to be used
without any feedback device in many traditional
closed loop applications.

Only the motor name plate data is required to
achieve optimum performance, the drive
continuously and automatically determines and
tracks the key motor characteristics required for
vector control.

Optidrive Plus 3
unique Optiwand CE Plus software designed for
use on pocket pc’s. Communication takes place
without wires using infrared light to quickly and
accurately transfer data.

Century Motor Control

Optidrive Plus 3GV’s revolutionary and patented 3
(3rd Generation Vector) vector control strategy
provides smooth, controlled full torque through zero
speed in open loop mode, without the need for motor
tacho-generators or encoders.

GV

The 3
drive for applications across the industrial spectrum.

Fast

and industrial washers. Powerful
starting torque applications like crushers and fully
loaded conveyors. Smooth
cranes.

Only motor nameplate details are required to achieve
optimum performance. Optidrive Plus 3
automatically performs an automatic tuning routine
measuring vital motor inductances, resistances,
currents and power factor with the motor at standstill.
After the initial tuning, these values are constantly
adapted in real time to ensure that performance is
maintained irrespective of changes arising out of
motor heating.

Non linearities are further corrected using highly
sophisticated measurement and compensation
techniques to give a very high quality sine wave
output. This results in smooth operation from zero up
to 2kHz
making this range of products ideal for high speed
applications such as machine tool spindles.

ultrafast torque control ensures it is the ideal
