Crane control
Crane control using parameter settings, not programmed
Drive application: Crane control
Loads need to be lifted and moved in almost all industries
all over the world. For example, on construction sites, at
transshipment stations, in warehouses and in assembly and
production halls.
These loads are lifted and moved by tower and gantry cranes,
trolley traveling winches, hoists and trolleys. The drives
on this machinery must be operated either manually
(ground-controlled) or remotely (radio-controlled). It goes
without saying that required safety instruments such as load
recognition and limit switch controls must also be
installed.
A typical crane control application is the gantry crane. In
this case, crane control can be used not only for the travel
axes but also for the hoist axis. The travel distance on
both travel axes must be limited with a limit switch. In
addition to limit switches, speed reduction switches are
normally installed to reduce the speed towards the end of
the stretch. For safety reasons, limit switches must also be
monitored. Load-controlled speed reduction optimizes
utilization of the power installed on the hoist axis.
The solution with MOVIDRIVE®
Set parameters instead of programming
The drive solution with MOVIDRIVE® is based on
the “Crane Control” application module. The “Crane
Control” application module is part of the MOVITOOLS®
MotionStudio software for MOVIDRIVE® and can be
accessed as soon as the license is purchased. The
user-friendly interface guides you through the process of
setting the parameters. Only those parameters required for
the specific application, such as fixed setpoints, ramps and
speed, must be entered.
The application module uses this information to create the
control program and loads it into the inverter. MOVIDRIVE®
then takes over the entire motion control. Users can also
opt to control the inverter with variable speed selection or
by fixed setpoints.
Wide range of functions
No matter how large the variety of applications for crane
control, the wide range of functions provided by the
application module provides the right solution for every
task.
- 6 fixed setpoints for multi-stage switching
- Variable speed in motor potentiometer mode.
- Switchover option between fixed setpoints and variable
speed regulation during operation.
- Speed reduction and limit switches are monitored.
- Speed is reduced when the speed reduction switches are
reached.
Movement control with IPOSplus®
One of the main MOVIDRIVE® features used in the
application modules is IPOSplus® positioning and
sequence control. Based on the specifications, an IPOSplus®
program in MOVIDRIVE® controls the entire
motion sequence with the application module as
machine-oriented as possible.
Further applications
In addition to gantry cranes, the "Crane Control"
application module can be used for further applications.
Examples are:
The advantages at a glance
- Wide range of functions
- User-friendly user interface
- You only have to enter the parameters needed for the
application
- Guided parameter setting process instead of
complicated programming
- No programming experience required
- Rapid familiarization with the system
- Choice of ground or radio control
- Movement control is carried out completely by the
IPOSplus® program in MOVIDRIVE®
- Limit switch control and load recognition
