General Information

• Manufacturer: Siemens AG
• Product Series: SIMOVERT MASTERDRIVES
• Product Type: Control & Interface Module (Option Module for Frequency Converters)
• Status: Discontinued (Obsolete, legacy component for older MASTERDRIVES systems)
• Target Systems: Compatible with Siemens SIMOVERT MASTERDRIVES VC (Voltage Source Converter) and MC (Motion Control) series frequency converters, used to expand communication capabilities and integrate with upper-level control systems.

Communication Specifications

1. Supported Protocols:
   • PROFIBUS DP: Complies with IEC 61158-2, functioning as a PROFIBUS DP slave device for communication with master controllers (e.g., SIMATIC S7 PLCs).
   • Serial Interface: Integrated RS485 serial port (optional, depending on firmware version) for point-to-point communication with HMI devices or other industrial controllers.
2. Communication Parameters:
   • PROFIBUS DP Baud Rate: Up to 12 Mbps (auto-adaptive to the master controller’s baud rate setting).
   • Data Exchange: Supports cyclic data exchange (for real-time control signals, e.g., speed reference, motor current) and acyclic data exchange (for parameterization and diagnostics).
   • PROFIBUS DP Ident Number: Pre-assigned device identifier for easy integration into PROFIBUS networks.

Functional Features

1. Control Integration:
   • Enables remote control of the MASTERDRIVES converter via the PROFIBUS DP network, including start/stop commands, speed/torque reference signal transmission, and status feedback (e.g., running state, fault alerts).
   • Supports parameterization of the MASTERDRIVES converter through the upper-level PLC (e.g., modifying motor rated parameters, protection thresholds) without local operation.
2. Diagnostics & Monitoring:
   • Transmits real-time diagnostic data to the master controller, including converter fault codes (e.g., overcurrent, overvoltage), operating parameters (e.g., output frequency, DC link voltage), and warning signals.
   • Provides LED indicators on the module for visual status monitoring (e.g., PROFIBUS communication status, power supply status, module fault status).
3. Compatibility with Control Modes:
   • Works with all standard control modes of MASTERDRIVES converters, including V/f control, vector control (without encoder), and closed-loop vector control (with encoder).

Electrical & Power Specifications

• Power Supply: Draws power directly from the host MASTERDRIVES converter’s internal 24 V DC power rail, requiring no external power source.
  • Input Voltage: 24 V DC ±10% (derived from the converter’s control circuit).
  • Power Consumption: < 3 W (low-power design to avoid overloading the converter’s internal power supply).
• Electrical Isolation: Galvanic isolation between the communication interface (PROFIBUS/RS485) and the converter’s internal circuits (isolation voltage: 500 V AC for 1 minute), preventing interference from electrical noise.

Physical & Environmental Specifications

• Dimensions: Approx. 80 mm (Width) × 120 mm (Height) × 40 mm (Depth) (compact form factor for installation on the MASTERDRIVES converter’s control unit slot).
• Weight: Approximately 0.2 kg.
• Mounting: Plug-in installation into the dedicated option slot on the MASTERDRIVES converter’s control panel (no additional mounting hardware required).
• Protection Class: IP20 (dust-protected, suitable for indoor industrial environments when installed within the converter’s cabinet).
• Operating Temperature Range: 0°C to +40°C (same as the host MASTERDRIVES converter’s operating temperature range).
• Storage Temperature Range: -20°C to +70°C.
• Relative Humidity: 5% - 95% (non-condensing).

Application & Replacement Notes

• Typical Applications: Used in industrial systems requiring networked control of MASTERDRIVES converters, such as conveyor systems, pumps, fans, and machine tool spindle drives, where centralized control via a PLC is needed.
• Replacement Options: As an obsolete product, it is replaced by communication modules for Siemens’ modern SINAMICS G120/G150/S120 series converters, such as the PROFIBUS DP module (6SL3255-0AA00-4BA1) for SINAMICS S120. These modern modules offer higher communication speeds, extended protocol support (e.g., PROFINET), and better compatibility with digital control systems.
• Firmware Dependencies: Requires compatibility with the host MASTERDRIVES converter’s firmware version (minimum firmware version V4.5 recommended). Firmware updates for the module are no longer provided by Siemens.
