VT-SWMA-1-1X/V0/0

The VT-SWMA-1-1X/V0/0 is a signal-processing module manufactured by Bosch Rexroth Indramat within the VT-SWMA Modules series. It is installed in hydraulic or electric drive cabinets to shape reference signals and manage motion profiles for proportional valves or inverters. By conditioning incoming setpoints and issuing controlled ramp commands, the module assists PLCs and motion controllers in achieving smooth acceleration and direction changes during industrial automation tasks.

The module accepts a differential command span of ±10 V, allowing a direct interface with common analog card outputs. All internal processing remains in the analog domain, so the analog signal path avoids conversion delays when controlling fast servo loops. Control electronics draw from a 24 VDC supply, simplifying power distribution because this level is standard for sensor and relay circuits in most machines. Field wiring is completed on plug-in screw terminals, which provide secure clamping and convenient access during maintenance. The housing snaps onto a DIN rail, so no additional brackets or screws are needed. It can be repositioned anywhere along the rail to optimize the panel layout.

During operation, the unit performs 4-quadrant recognition, so it automatically distinguishes between positive and negative velocities and responds accordingly without external logic. A dedicated input enables command value call-up, allowing an external switch to load predefined setpoints for rapid recipe changes. For motion sequences that require gradual transitions, a separate input activates ramp time call-up, overriding the internal time constant with a preset slope to prevent hydraulic shock or mechanical stress. The enclosure weighs only 0.22 kg, keeping additional mass in control cabinets to a minimum and allowing the device to be mounted on light-gauge DIN rails without reinforcement.
