Application-Specific FAQ
Q: Can the 6SE6440-2UD31-5DA1 control a pump in a closed-loop PID configuration?
A: Yes. The MM440 has a built-in PID controller (P2200–P2285 parameter group) that accepts a 4–20 mA or 0–10 V feedback signal directly, eliminating the need for an external PLC for simple pressure or flow control loops.
Q: Is this drive compatible with SIMATIC S7 PLCs via PROFIBUS?
A: Yes, with the optional CB PROFIBUS DP module (6SE6400-1PB00-0AA0) installed, the drive integrates natively with S7-300, S7-400, and S7-1500 PLCs using standard GSD files.
Q: What motor types are compatible?
A: The 6SE6440-2UD31-5DA1 is designed for standard 3-phase asynchronous (induction) motors. It also supports permanent magnet synchronous motors (PMSM) in sensorless vector mode with appropriate parameter configuration.
Q: Can it be used in a hazardous area (ATEX zone)?
A: The drive itself is IP20 rated and not ATEX certified. However, it can control ATEX-certified motors installed in hazardous zones when the drive is mounted in a safe area control panel.
Q: What is the difference between 6SE6440-2UD31-5DA1 and 6SE6440-2UD33-0EA1?
A: The 6SE6440-2UD31-5DA1 is rated at 15 kW / 34 A, while the 6SE6440-2UD33-0EA1 is rated at 30 kW / 62 A. Both are MM440 series with identical control architecture but different power stages.
