Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 16271812 (MCS09H41-RS0B0-RS0) is a permanent magnet synchronous servo motor from the Lenze MCS product family. Built in frame size 09 with length H, this motor delivers high dynamic responsiveness and compact power density for automated machinery, including packaging positioning drives, material handling gantries, and continuous rotary indexing tables. It features a rated speed of 4100 RPM, a continuous stall torque of 4.5 Nm, a rated torque of 3.8 Nm, and peak torque performance up to 18.5 Nm driven by a peak current capability of 22 A. Standardized with an IP65 protection rating, this version is configured without a mechanical holding brake (B0 designation), making it suitable for horizontal axes and applications utilizing external braking mechanisms.
Electrical power and resolver feedback connections are made via SpeedTec circular plug connectors, allowing reliable interface with matching SpeedTec cable assemblies. Commissioning a replacement unit requires transferring motor parameters and conducting resolver offset alignment within the host servo inverter, such as a Lenze 9400 HighLine or i700 series drive. Parameter configuration and calibration routines are executed using Lenze EASY Starter or Lenze Engineer software tools. When bringing a spare unit into operation, establishing accurate drive profile parameters and resolver commutation alignment is essential before placing the axis into continuous motion control. Technical assistance from ABC Industrial Parts can assist with parameter verification and commissioning requirements.
Thermal conditions within the motor windings are continuously monitored by an integrated KTY84-130 or PT1000 temperature sensor evaluated directly by the connected servo inverter. The host drive processes operational states, feedback integrity, and motor fault conditions, surfacing diagnostic notifications on the keypad or engineering software interface. Initial fault checks should focus on verifying SpeedTec connector seating, testing thermal sensor resistance, and inspecting resolver wiring for signal continuity. Internal stator, rotor, or bearing damage cannot be serviced in the field; replacing the motor or utilising tested repair services through ABC Industrial Parts provides a direct route back to active production.

Programming and Configuration
Commissioning the Lenze MCS09H41-RS0B0-RS0 servo motor is carried out through the connected Lenze servo drive using Lenze EASY Starter or Lenze Engineer engineering tools. The drive must be configured with the specific electrical and mechanical characteristics of the motor, including current limits, maximum torque levels, speed constraints, and thermal trip thresholds matching the motor winding specification.
Proper position feedback alignment is required during setup. The integrated resolver (RS0) must undergo zero-point offset calibration within the drive software to ensure correct commutation angle timing. Accurate offset alignment allows the servo drive to deliver precise vector control and maximum torque output up to the 4100 RPM rated speed limit.
Communication and System Integration
The Lenze 16271812 motor connects to power and feedback wiring using standardized SpeedTec circular plug connectors. These quick-locking connectors allow fast and secure connection using matching SpeedTec motor cables, helping streamline assembly and replacement procedures.
This motor integrates directly into automation systems powered by Lenze servo drives, such as the 9400 HighLine and i700 series inverters. The drive evaluates resolver signals for position and velocity feedback while continuously monitoring internal winding temperature via the integrated KTY84-130 or PT1000 thermal sensor over the feedback cable.
Diagnostics and Status Indication
Diagnostic feedback for the MCS09H41-RS0B0-RS0 motor is managed directly through the host servo inverter. Thermal conditions within the stator windings are monitored continuous by the embedded KTY84-130 or PT1000 temperature sensor, allowing the drive to register warnings or execute safe shutdowns before overtemperature damage occurs.
System operators can review diagnostic states, fault logs, and feedback health using the connected drive's operator keypad or software diagnostic windows. Drive-level diagnostics assess resolver signal quality, motor phase current draw up to peak limits of 22 A, and thermal sensor feedback to identify operational anomalies.
Replacement and Spare Part Considerations
When installing a spare motor to replace a faulty unit, confirm that the full part designation MCS09H41-RS0B0-RS0 matches. Critical features specified in this code include the frame size 09 length H, 4100 RPM rated speed, resolver feedback (RS0), and unbraked configuration (B0). Replacing this device with a motor that differs in feedback type or brake inclusion will cause drive fault conditions or improper axis operation.
Before applying operational power to a newly installed replacement motor, ensure that SpeedTec cable connectors are locked securely in position. Recommissioning requires verifying that the connected servo drive contains the correct motor parameter profile and executing a resolver offset calibration procedure in Lenze EASY Starter or Lenze Engineer software.
