Selection Guide
Use this guide to select the correct communication module for your MM430/MM440 drive:
- Step 1 – Identify your fieldbus protocol: PROFIBUS DP, DeviceNet, CANopen, or Modbus RTU?
- Step 2 – Confirm drive firmware version: Check P0018 on the drive keypad. Firmware ≥ 3.x recommended for full module support.
-
Step 3 – Match part number to protocol:
- PROFIBUS DP → 6SE6400-1PB00-0AA0 / A5E00677650
- DeviceNet → 6SE6400-1PC00-0AA0
- CANopen → 6SE6400-1PD00-0AA0
- Modbus RTU → 6SE6400-1PE00-0AA0
- Step 4 – Verify slot availability: MM430/MM440 supports one communication module slot. Remove existing module before installing.
- Step 5 – Contact Konmask: Not sure? Send us your drive nameplate data and network topology — we’ll recommend the right module.

Replacement & Compatibility FAQ
Q: Is A5E00677650 the same as 6SE6400-1PB00-0AA0?
A: These part numbers may refer to the same or closely related PROFIBUS module variants. Contact Konmask with your drive details for a definitive cross-reference confirmation.
Q: Can I use a third-party PROFIBUS module instead of the original Siemens part?
A: Third-party modules may work via RS485/PROFIBUS bridging, but full P-parameter access and Siemens warranty compliance require the original OEM module. Konmask can advise on validated alternatives.
Q: My MM440 shows fault F0070 after installing the module. What should I do?
A: F0070 indicates a communication module fault. Check that the module is fully seated, verify P0700 (command source) and P1000 (frequency setpoint source) are set to fieldbus (value 6), and confirm the PLC master is actively sending cyclic data.
Q: Does this module work with Siemens G120 drives?
A: No. The G120 series uses a different module interface. You need the PROFIBUS module 6SL3055-0AA00-2xx0 for G120 drives.
Q: What is the warranty on parts purchased from Konmask.com?
A: All genuine Siemens parts carry a 12-month warranty from date of shipment. Contact support@konmask.com for warranty claims.
