Integrated Motion Controller (IMC)

The Integrated Motion Controller (IMC) functionality in VLT® AutomationDrive FC 302 and VLT® Decentral Drive FCD 302 enables high-precision positioning and synchronization tasks without requiring additional hardware or complex programming. It offers cost-effective alternatives to servo drives for single-axis applications, supporting sensorless control to further reduce costs and complexity.

Positioning Modes:

• Absolute positioning: Target position relative to a defined zero point.
• Relative positioning: Target position relative to the current position.
• Touch probe positioning: Target position relative to a signal on a digital input.

Synchronization Mode: Allows a drive to follow a master signal, with adjustable gear ratio and position offset.

Homing: Required after power-up to establish a reference for physical position, with various sensorless and sensor-based functions available.

Safety Features

The VLT® AutomationDrive family is delivered standard with the STO (Safe Torque Off) function, compliant with ISO 13849-1 PL d and SIL 2. This can be extended with options like SS1, SLS, and SMS using the VLT® Safety Option MCB 150 Series. MCB 150 and MCB 151 modules provide SS1 and SLS functionality, while MCB 152 enables safety functions via the PROFIsafe fieldbus.

Condition-Based Monitoring (CBM)

The VLT® Drive acts as a smart sensor, monitoring motor and application conditions in real-time. CBM functions establish baselines and threshold values to detect deviations and alert operators. It complies with standards like ISO 13373 and VDMA 24582, enabling proactive maintenance and reducing unplanned downtime.

Key CBM Functions:

• Motor-stator-winding condition monitoring: Detects motor isolation faults early.
• Mechanical-vibration monitoring: Monitors vibration levels using external transducers, adhering to ISO 13373 and ISO 10816 standards.
• Load-envelope monitoring: Compares actual load curves to initial values to detect unexpected operating conditions.

Drive as a Controller
