Standard applications
The standard applications encompass various pre-configured
projects, which are ready for use to address various crane appli-
cations:
•
Single-axis application for hoist, trolley or gantry with control
via the onboard terminal strip or via PROFIBUS DP
•
Two-axis application for master-slave closed-loop torque
control
•
Setpoint via a digital and an analog master switch
•
Selectable using a script screen form
These solutions are suitable for "ready-to-run" applications
(parameterized) or "ready-to-apply" applications (DCC). As a
consequence, expandability and flexibility have been taken
into account.

Technology
Brief description
1
Load-dependent field weakening
Calculates the supplementary speed setpoints dependent on the load. When compared to full loads,
partial loads automatically operate at a higher speed.
2
Prelimit switch (selectable limiting)
Allows the drive velocity to be limited when a pre-defined prelimit switch is reached.
3
Start pulse
Prevents "load sag" when hoists start with a suspended load.
4
Current distribution monitoring
Compares the current setpoints or actual values from the master and slave, and issues a signal for a
deviation from a specified value.
5
Master switch
(digital or analog)
Facilitates a high drive travel precision via a directly connected master switch for manual positioning.
6
Monitoring for overspeed
Monitors for overspeed or detects deviations between speed setpoints and actual values.
7
Time-optimized positioning for a single axis
Allows the drive to be precisely traversed to the target position with the specified, maximum velocity
and acceleration/deceleration within the shortest time.
8
Master-slave closed-loop torque control
When 2 motors operate on a common shaft, the master issues the torque setpoint for the slave. The
master operates either closed-loop speed controlled or position controlled. The master-slave drive
must be networked as part of the application (application engineering).
9
Brake control
The simple or extended brake control allows the user to parameterize rather than program the control. The
combination of start pulse and brake control simplifies the engineering and commissioning for the user.
10
Safety Integrated
If required, the SINAMICS Safety Integrated Basic and Extended Functions are available for the user,
e. g. STO, SLS.
