FLUX VECTOR LIFT DRIVE
The Vacon Drive is our
standard drive system and
is used up to 1.6m/s. This
compact unit is designed
and manufactured to a high
specification in Finland and
is used world-wide in many
industrial applications.
We also use the Ziehl Drive
from 1m/s – 2.5m/s for
geared and gearless systems.
The Ziehl Drive with a direct
floor approach will give
fast brake to brake time
required in today’s modern
office blocks.
Both drives are proven in
the lift industry and have
the following features: |
 |
 |
- Software designed specifically for lifts
- Accurate motor modelling for close control
- Adjustable switching frequency for quieter operation
- Full Flux Vector operation with Encoder
- Sensorless Flux Vector Operation
without Encoder (Vacon only)
- User-friendly interface and menus
- Built in filters and DC line choke
- Four Quadrant operation option with
regenerative energy feed back into mains and reduced harmonic distortion
- Pre-set parameters to aid commissioning
- Speeds set in metres per second with
accel/decal rates in metres per second squared
- Fully adjustable S ramps for smoother
ride comfort
- Can be commissioned from a laptop

DC DRIVE CONTROL
Our preferred drive
for use with DC
Motors is the
Magnetek DSD412
DCSCR Drive.
This drive utilises
digital technology
to give a smooth
controlled ride – it is
a well-established
brand within the lift
industry both in the
UK and abroad.

BUCHER VVVF
HYDRAULIC SYSTEM
We can also incorporate
the Bucher VVVF
Hydraulic Drive System
within our control
system. We use special
cards to control the
sequence of release of
the contactors and
drive, thus ensuring the
reliability of the drive
well in to the future.
