Features & technology

SIMOCRANE Drive-Based Technology encompasses the following features:

  • All of the functions that have been proven in practice and required for mid-performance applications can be found on the new SINAMICS platform for parameterization

  • Preconfigured standard applications for hoist and trolley/gantry with control via PROFIBUS DP or via I/O signals (ready-to-run, only have to be parameterized using script)

  • Can be adapted to address customer-specific requirements - "ready-to-apply" (for adaptation by the user)


Technology

Brief description

Load-dependent field weakening (LoadDependingFieldWeak)

Using the LoadDependingFieldWeak DCC block, a supplementary speed setpoint is calculated as a function of the load. This speed increase for partial loads above the rated speed is required for cranes to increase the handling capacity.

Prelimit switch (selectable limit)(PreLimitSwitch)

Using this DCC block, when a pre-defined pre-limit switch is reached, the drive velocity can be limited.

Start pulse
(StartPulse)

Using this DCC block, "load sag" when starting hoisting gear with a suspended load is prevented.

Current distribution monitoring(CurrentDistribution)

This DCC block is used to compare the current setpoint or actual value of the master and slave. A signal is generated if a specified difference is exceeded.

Master switch
(MasterSwitch)

Using this DCC block, the drive can be moved with a high degree precision via a directly connected master switch for manual positioning.

Overspeed monitoring(OverSpeed)

Using the DCC block OverSpeed, the overspeed can be monitored or a setpoint-actual value deviation can be identified (this is not a fail-safe function).

Time-optimized positioning for a single axis
(basic positioner)

Using the function module "basic positioning" in SINAMICS, the drive can be moved to the target position as quickly as possible and precisely with the specified maximum velocity and acceleration/deceleration.

Master-slave torque control(Master-Slave-Torque-control)

Master-slave operation is used if two motors are connected to a common shaft. The master operates either in the closed-loop speed or position controlled mode, the slave operates in the closed-loop torque controlled mode. The master sends the torque as torque setpoint to the slave. The communication between master-slave drive must be realized as part of the application solution.
