Hardware configuration
Typical hardware configurations used in mid-performance crane
applications are shown in the following examples. It involves an
overhead bridge crane (OHBC), controlled using I/O signals or
using PROFIBUS DP communication.
It is especially important to note that the crane can be controlled
just using the onboard I/O (see "Topology with onboard I/O") with
SIMOCRANE Drive-Based Technology V1.0 SP1 HF2.
For hoist applications, an encoder is required for safety reasons.

Software
•
Special SINAMICS Firmware V4.7 HF11 for crane applica-
tions. The following Power Modules and functions can be
operated using this firmware:
- PM340 Power Module (2-quadrant operation)
- Power Module in chassis format (2-quadrant operation)
- PM250 Power Module (4-quadrant operation)
- Safety Integrated functions
- Vector control,
V/f
control
- NO servo control
•
Crane technology in DCC blocks, e.g. load-dependent field
weakening, start pulse etc.
•
Standard applications via PROFIBUS or via onboard
I/O terminals for the single axis of the hoist, trolley or gantry
(selectable using the appropriate scripts)
•
SINAMICS functions, e.g.:
- Master-slave closed-loop torque control
- Brake control logic
- Time-optimized positioning
- Safety Integrated function
