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.
