Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Siemens 6SE6400-1PB00-0AA0 is an optional PROFIBUS DP communication board designed for the MICROMASTER 4 family, integrating with MICROMASTER 420, 430, and 440 frequency inverters. Functioning as a fieldbus interface module, this unit plugs directly into the host drive's option slot and receives its internal 5 V DC supply voltage (drawing a rated current of 100 mA) directly from the inverter without needing external supply wiring. Featuring a compact form factor measuring 161 mm in height, 73 mm in width, and 43.5 mm in depth, the board facilitates centralized drive monitoring, remote speed reference control, and parameter management in industrial factory automation environments.
Network coupling is provided via a standard 9-pin Sub-D female RS-485 interface connector that supports transmission speeds from 9.6 kbps up to 12 Mbps. The module supports full PROFIBUS DP-V1 functionality, permitting fast cyclic process data exchange alongside acyclic parameter reading and writing. Engineering and integration are managed using tools such as STEP 7, STARTER, or DriveMonitor with standard GSD configuration files. When mounted on larger MICROMASTER 4 FX and GX frame sizes, the right-angle PROFIBUS connector 6GK1500-0EA02 must be utilized to maintain required physical clearance. Commissioning a replacement unit is simplified because drive network settings, including the PROFIBUS bus address in parameter P0918, are preserved directly within the host inverter's memory. ABC Industrial Parts can assist in verifying hardware replacement requirements and drive parameter configurations.
Visual status indication is provided through front-panel diagnostic LEDs that display module power, internal drive link activity, and fieldbus communication health. Advanced numerical diagnostic information can be read out through drive parameters r2054.00 through r2054.08, which present the ASCII module name, code line errors, and detailed diagnostic status. Network disruptions between the DP master and the option board generate fault code F0070 (CB setpoint fault), typically caused by disconnected bus cables, incorrect bus termination, or a stopped master controller. Initial troubleshooting should focus on inspecting cabling, termination resistors, and master PLC states. If internal electronic or hardware failures occur, sourcing a tested replacement module from ABC Industrial Parts offers an effective path to restoring drive system operation.

Programming and Configuration
Integrating the Siemens 6SE6400-1PB00-0AA0 option board into a host automation architecture is performed using standard Siemens software environments, including STEP 7, STARTER, or DriveMonitor. System setup requires loading the corresponding GSD file into the engineering station to define the drive node on the PROFIBUS DP bus. The software enables configuration of cyclic process data words, such as control words and velocity setpoints, as well as acyclic communication paths for extended parameter access.
Parameters controlling the fieldbus interface are maintained within the non-volatile memory of the host MICROMASTER 4 inverter rather than on the option board itself. Key settings, such as the PROFIBUS station address, are configured in inverter parameter P0918. Because network attributes reside in the inverter memory, swapping an existing option board with a replacement unit requires no software re-downloading, as the host drive retains and applies the existing network parameters automatically.
Communication and System Integration
The 6SE6400-1PB00-0AA0 provides fieldbus networking via a 9-pin Sub-D female RS-485 interface connector. Capable of communicating at data rates spanning from 9.6 kbps up to 12 Mbps, the module automatically detects and synchronizes to the active transmission rate designated by the PROFIBUS DP master controller.
Fully compliant with the PROFIBUS DP-V1 standard, the module supports both cyclic data transmission for real-time motor control and acyclic data exchange for detailed parameter reading and write access. For physical mounting on larger MICROMASTER 4 FX and GX frame sizes, the right-angle PROFIBUS connector 6GK1500-0EA02 is required to achieve correct cable orientation and mechanical clearance within the inverter assembly.
Diagnostics and Status Indication
Front-panel multi-state diagnostic LEDs provide continuous visual feedback regarding module operational health. These indicators monitor internal 5 V DC logic power delivery, internal communication link activity between the board and the host drive, and active connection status on the PROFIBUS fieldbus network.
Detailed software-based diagnostic feedback is available through host drive parameters r2054.00 through r2054.08. Parameter r2054.05 displays the module name in ASCII code, while r2054.06 indicates the internal code line associated with a detected error. Parameters r2054.07 and r2054.08 provide extended diagnostic error details to assist maintenance engineers during fault analysis.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Module Diagnostic LEDs | Multi-state | Indicates module power, internal communication status with the host inverter, and PROFIBUS fieldbus connection state. |
Replacement and Spare Part Considerations
When replacing a failed 6SE6400-1PB00-0AA0 board, parameter adjustments are minimal because operational settings and bus node addresses (P0918) are stored directly in the host MICROMASTER 4 inverter. Inserting a replacement board into an existing host drive allows the module to draw power and begin communicating immediately using the previously stored parameter set.
Mechanical considerations must be addressed when servicing larger drive frame sizes. While standard MICROMASTER 420, 430, and 440 drives accept standard straight PROFIBUS connectors, FX and GX frame sizes require the dedicated right-angle 6GK1500-0EA02 connector to prevent mechanical interference with surrounding enclosures.
If network link issues persist following hardware installation, technicians should verify that active bus termination resistors are powered and positioned correctly at both physical ends of the RS-485 cable segment. Reviewing parameter r2054 on the inverter operator panel helps confirm whether communication interruptions stem from external bus wiring or internal interface processing.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| F0070 | CB setpoint fault | Communication telegram failure between PROFIBUS DP master and the communication module during operational state. | PROFIBUS cable disconnected, master controller stopped, bus termination incorrect, or communication timed out. | Check PROFIBUS cable and connector, check master PLC state, check telegram timing settings, verify bus termination resistors. |
Frequently Asked Questions
Does the 6SE6400-1PB00-0AA0 module require an external power supply?
No. The module is powered internally from the host MICROMASTER 4 inverter via the option slot connection, drawing 5 V DC at a rated current of 100 mA.
Do I need to re-configure the PROFIBUS address when installing a spare module?
No. The PROFIBUS bus address is set in host drive parameter P0918 and saved in the inverter's non-volatile memory. A replacement module automatically uses the existing parameter stored in the drive.
Which software tools are used to configure the 6SE6400-1PB00-0AA0 module?
Configuration and drive integration are performed using Siemens engineering software such as STEP 7, STARTER, or DriveMonitor along with standard GSD files.
What connector is required for MICROMASTER 4 FX and GX frame sizes?
MICROMASTER 4 FX and GX frame sizes require the right-angle PROFIBUS connector 6GK1500-0EA02 to ensure proper mechanical clearance.
What causes fault code F0070 on a drive using this option board?
Fault code F0070 indicates a telegram communication failure between the PROFIBUS DP master and the option board. Common causes include a disconnected bus cable, incorrect bus termination resistors, a stopped PLC master, or telegram timeouts.
