Siemens 6SE7090-0XX84-0FF5 SIMOVERT MASTERDRIVES CBP2 Communication Module

The Siemens 6SE7090-0XX84-0FF5, also cataloged as the 6SE7090-0XX84-0FF5 COMMUNICATION MODULE, operates as a dedicated hardware component for high-speed cyclic data transmission, motion control coordination, and PROFIBUS network interfacing within SIMOVERT MASTERDRIVES drive architectures.

Hardware Specifications

Industrial Control and Drive Integration

• Harmonic Distortion Suppression: The communication board is electrically decoupled from the main inverter bus using onboard galvanic isolation filters. This layout ensures that high-frequency electrical switching noise from the IGBT power section does not corrupt network frames, sustaining reliable harmonic distortion suppression across the physical PROFIBUS segment.
• Actuator Loop Feedback Response: Utilizing the PROFIBUS DP V1/V2 protocol with CBP2 hardware enables sub-millisecond bus synchronization cycles. This transmission speed allows the host PLC to read position, speed, and torque values instantly, maintaining a tight actuator loop feedback response for precise multi-axis motion control.
• Thermal Heat Sink Dissipation Profiles: The module installs directly into the drive’s internal option slot matrix, aligning flush with the internal cooling paths. This integration allows the board to operate reliably within the drive's thermal heat sink dissipation profiles, protecting the onboard communication processors from heat degradation.

Frequently Asked Questions

Q: What technical tracking behavior manifests inside the master controller if the PROFIBUS cable is disconnected from the CBP2 module during operation?

A: The CBP2 module registers the missing token or carrier wave instantly, tripping its internal bus watchdog timer. It flags a peripheral communication fault to the drive's main control board, which immediately executes a configured fault reaction (such as a coast-to-stop ramp) while sending a telegram timeout alarm to the upstream PLC.

Q: Can this 0.11 lbs CBP2 communication card be plugged into the MASTERDRIVES electronic box while the control electronics are powered?

A: No. The internal option slot backplane interface does not use staggered pin allocations or power pre-charging networks designed for hot-swapping. Inserting or extracting this option board while the drive’s 24 VDC auxiliary power or main DC link is active can cause severe electrical transients, risking permanent destruction of the logic processor on both the card and the drive unit.
