6SE6400-0EN00-0AA0 Siemens MICROMASTER 4 Encoder Module TTL/HTL Incremental Encoder Board  MM440 Closed-Loop

Product Overview: Siemens 6SE6400-0EN00-0AA0

Parameter Specification
Brand Siemens
Order Number 6SE6400-0EN00-0AA0
Product Family MICROMASTER 4 (MM420/MM440) option module
Product Type Encoder evaluation / feedback module (option board) — not a drive or power module

Application & Fault Scenarios

Typical Uses: Adds real speed feedback to MM440 drives for closed-loop vector control in printing & converting lines, winders/unwinders, textile machines, long conveyors requiring master–slave synchronisation, and crane/hoist applications needing reliable four-quadrant operation. Also used where precise low-speed torque or "flying restart" onto a spinning motor is required.
Common Field Issues:
  • F0090 encoder signal loss → broken cable, wrong TTL/HTL DIP setting or reversed A/B channels; check shielding, continuity and P0408 ppr setting.
  • Unstable vector control / motor hunting → encoder direction disagrees with motor rotation; verify r0061 sign vs actual rotation, swap A/B or set P1820=1.
  • No speed feedback at all → 5 V/18 V supply missing or overloaded; check LK/18V link, encoder current draw (≤330 mA @5 V / ≤140 mA @18 V) and fit external supply if cable > 50 m.
  • Noise/interference after installation → run encoder cable separately from power cables, use twisted screened pair, earth screen at one end and avoid the 120 Ω terminator with HTL encoders.

FAQ

Q1: What is the Siemens 6SE6400-0EN00-0AA0?
A: It is the MICROMASTER 4 encoder evaluation module — an option board for MM440 that reads incremental TTL/HTL encoders (up to 300 kHz, 5000 ppr) to enable closed-loop vector control and hoisting applications.
Q2: Which encoders can I connect?
A: Single-channel or quadrature (A/B) incremental encoders, TTL (5 V) or HTL (18–24 V), selected by on-board DIP switches/links. Absolute encoders are not supported; zero-pulse inputs are ignored by MM4.
Q3: Do I need an external power supply for the encoder?
A: Only if the encoder draws more than 330 mA at 5 V or 140 mA at 18 V, or if the cable exceeds 50 m. Otherwise the board's own short-circuit-protected supply is sufficient.
