Examples of crane functionalities created with DriveAP
Main contactor control logic
Using Adaptive Programming (AP), you can create a main contactor control logic for
the 3-phase power supply of the ACS800 drive. With the help of the main contactor
control logic, the power supply of the drive is disabled when the crane is not used
(the standby energy-efficiency mode).
For an example how to create the AP file, see Main contactor control logic on page
297 .
Brake match
Brake match detects mechanical brake slips and downward movement of the load
when Mechanical brake control is in use, the operator has given the stop command
and the target is to close the brake. The slip detection is based on the motor encoder
position signal, and the function works only if an encoder is used. You can use the
function for an automatic restart of the crane or just for a warning (alarm) indication.
For an example how to create the AP file, see section Brake match on page 301 .
Redundancy in Master/Follower crane control
In the Master/Follower crane control, redundancy is implemented using a spare drive
unit that is ready to be used as a Master or a Follower. The spare unit usually
replaces the faulty Master or one of the Followers.
Adaptive Programming provides the ability to switch between the Master, Follower or
standby (spare unit) mode. This means that the Master and Follower are no longer
fixed, but can be changed when needed.
Using the Adaptive Programming (AP), you can create a redundancy control logic.
For an example how to create the AP file, see
Redundancy in Master/Follower crane
control on page 304 .
Scaling actual encoder position signal (mm) to analogue output as mA
The actual encoder position signal 02.21 POS ACT PPU (mm) can be scaled to
4 … 20 mA for analogue outputs and sent to other systems as an mA signal, for
example, for supervision or protection purposes.
Using Adaptive Programming (AP), you can create an AP file for scaling the actual
encoder position signal for an analogue output. For an example how to create the
AP file, see
Scaling actual encoder position signal (mm) to analogue output as mA
on page 310 .
Slack rope torque detection
Using Adaptive Programming (AP), you can create a function for detecting slackness
of the ropes on the drum. The detection is based on monitoring the motor torque. For
more information, see
Slack rope torque detection on page 311 .
Conical rotor motors
Using Adaptive Programming (AP), you can create a file for handling brake control of
conical rotor motors that do not have an external brake. With the help of Adaptive
Programming, the conical rotor motors can be used together with the Crane control
program. For more information, see
Conical rotor motors on page 313 .
