coding
D2L can be summarized as a "crane hoisting motor control system, which controls the speed by changing the
frequency of supply voltage of a squirrel cage motor". A stepless speed adjustment can be achieved by this
method.

description
D2L has many advantages and offers many new features, when compared to other inverter based systems,
which might be used in crane applications.
Inverter
The inverter in D2L is a crane inverter. The specific crane features for the inverter hardware and the special
software are achieved by combining the experience and know-how of crane applications with the latest
technology. The inverter uses vector calculation for several different motor control modes.
Crane user interface
All D2L has exactly the same interface with pre-designed locations for typical crane functions. The main part of
this interface is carried out by a terminal strip, which has separated sections for signals with main, control and
electronics voltage levels.
Brake control
D2L include the brake contactor for disk brakes. D2L also includes it’s own DC-rectifier.
Electrical
Braking
D2L includes the braking transistor, which is dimensioned for every crane application. For resistor braking D2L
includes a braking resistor.
Control methods
D2L can be controlled by the electronic potentiometer control with 2-step or 3-step pushbuttons and by the
multistep control with 2-4-step controllers. Both these control methods are available with every D2L.
Limit switch functions
D2L has built-in slowdown (S11, S21) and stop limit switch (S12, S22) functions for both running directions.
Speed supervision
D2L includes a speed supervision unit SSU, which is separate from the inverter and not dependent on software.
This safety circuitry is used to monitor the speed of the motor. In case of speed difference, overspeed or stall the
speed supervision unit stops the motion immediately.
Protections
D2L includes a motor thermal protection, which is based on motor temperature measurement by thermistors
placed in motor windings. A great number of other protections included in every D2L are shown in the technical
data.
Tested parameters
D2L includes tested parameters with different motors for all power ratings. This is a benefit, which makes every
D2L delivery a proven solution The tested and pre-set motor parameters enable a quick start-up
