Bosch Rexroth R911424959

What is the Bosch Rexroth R911424959?

With the ctrlX DRIVE Runtime licence ""Productivity"" for ctrlX DRIVE double-axes devices, the functional scope of the Runtime will be extended by the following features:

Motor control:

- Enhanced PWM switching (frequency halving in the standstill range, load-dependent and master-side switching)

- Motor holding brake with brake current monitoring (ECO)

- Axis control: Measuring wheel mode

Compensation functions/corrections:

- Precision axis error correction

- Reversal clearance compensation

- Friction torque correction

- Automatically compensating the load due to weight

- Temperature error correction

- Quadrant error correction

- Cogging torque compensation

- Adaptive velocity control loop gain

- Hybrid velocity control (velocity mixing)

- Hybrid position control

- External torque/force feedforward

- Velocity control with reference model

- Velocity control loop filter > 3

- Anti-vibration filter

Power supply:

- Internal DC bus short circuit at 24 V power failure

- Braking resistor to generate process heat

DC/DC converter:

- Load-dependent PWM frequency switching controlled by control unit

Island grid mode:

- Island grid mode, closed-loop controlled

- Island grid mode, open-loop controlled

- Dynamic switching from mains operation to island grid mode

- Synchronization to mains

- Mains transformer

- Voltage synchronization via characteristic curves

- Black start

Establishing the dimensional reference (encoder function):

- Set/shift coordinate system

Other encoder functions:

- Redundant motor encoder

Axis/inverter operation modes:

- Positioning block mode

Error reactions:

- Return motion

- Sensorless deceleration in the case of encoder error

Additional Motion functions:

- Spindle positioning
