1 Introduction
EMOTRON the leading brand for lift and conveyor technology!
A field-orientated lift inverter with MULTIDRIVE DSV 5445 LIFT direct entry:
Up to 60% energy saving compared to thyristor actuators.
Reduced starting current (1.2 l
N
max. factory adjustment).
Use of single-speed proprietary standard motors possible without special forced-ventilation
blowers.
Special pulse-width modulation method (10-15 kHz) for «whisper-silent running», no speed
dependent noise.
Conservation of motor winding without additional choke by dv/dt limitation, therefore also
suitable for converting existing systems.
High efficiency 97% at 65% duty cycle (< 45° ambient temperature, 10 kHz).
High control performance and optimum concentricity using field oriented current control with
typically 65536 points per motor revolution. All common encoder types and number of pulses
per revolution are possible.
Braking energy dissipated using commercially available resistor cage or using "cos phi = 1"
energy recovery unit. No mains reactive power.
Emergency evacuation possible with USV or battery supply (option).
Optimum factory presetting, very simple operation using customised menu. Lift data like
suspension, translation, number of gears and driving wheel diameter can be input in current
physical units. Automatic fine control using fuzzy controllers.

. Detailed customer
information with application examples.
One inverter for all drives: Gearless (synchronous/asynchronous), epicyclical gear, hypoid gear,
worm gear, V-belt and even hydraulic drives are possible!
The devices handles lift speeds up to 6.0 m/s and supplies all necessary signals for
commercially available lift controllers. Constantly reproducible levelling control is possible to
within < 0.5 mm with direct approach.
No problems with CE and EMC directives when patented AddOn filter technology is used.
Optimum data administration using project-linked data storage with PC/laptop. Updates
guaranteed to be compatible with preceding releases.
Standardised lift program (also for digital integral shaft copy)
Unique encoder evaluation process (65536 increments per revolution) guarantees quiet motor
operation even at slow speeds!
Special versions for synchronous and asynchronous gearless winches with 50 MHz controller
card and options for different encoder systems (SSI combined encoder, 8-channel 1Vpp,
resolver, etc.).
Special versions with integrated shaft copy (for storage and retrieval unit and lifting axles).
User interface via a convenient PC program (under W95, W98, ME, W2000, NT, XP).
