Lenze 13314406 MDSKSAG071-03 AC Synchronous Servo Motor
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13314406 MDSKSAG071-03 is a three-phase AC synchronous servo motor from the Lenze MDSKS Series, designed for high-dynamic positioning and continuous-duty motion processing. Engineered in a compact 071 frame size with a 6-pole internal layout, this self-cooled motor operates on a 400V AC voltage category and provides a rated speed of 3000 rpm. It delivers a standstill torque of 4.2 Nm, a continuous rated torque of 3.3 Nm, and peak torque capabilities up to 15.5 Nm to support rapid acceleration cycles across automated production systems such as packaging lines, material handling equipment, machine tools, and textile machinery.
Connecting the MDSKSAG071-03 into a motion control system requires matched power and feedback cabling via SpeedTec circular connectors. The motor relies on an integrated resolver feedback system to transfer speed and positional data back to 400V or 480V mains-operated Lenze servo drives. When commissioning a replacement motor, drive parameters must be verified using engineering tools such as Lenze EASY Starter or Global Drive Control (GDC) software to align feedback zeroing and current thresholds (with a rated current of 3.1 A and maximum current limit of 16 A). Support from ABC Industrial Parts can assist maintenance teams in verifying component identity and drive configuration alignment to minimize machine downtime.
Diagnostic monitoring for the motor is managed through the connected Lenze servo inverter and internal monitoring sensors. An integrated KTY84-130 / PTC thermal sensor continuously feeds winding temperature measurements back to the drive to guard against thermal overload during heavy duty cycles. First-line troubleshooting for suspected drive faults includes verifying circular connector seating, inspecting power and resolver cables, and evaluating drive-based status messages in EASY Starter or GDC. If internal winding breakdown, mechanical bearing damage, or resolver faults occur, obtaining a tested replacement unit or utilizing repair options through ABC Industrial Parts provides a direct route back to reliable production status.

Programming and Configuration
Commissioning and parameter setup for the Lenze MDSKSAG071-03 are conducted through the host Lenze servo drive using Lenze EASY Starter or Global Drive Control (GDC) engineering software. Motor operating profile parameters—including rated speed (3000 rpm), continuous rated current (3.1 A), standstill current (3.6 A), and peak current capacity (16 A)—are established in the drive setup to maintain controlled dynamic performance.
Proper drive setup ensures closed-loop motor management by coordinating the drive controller's commutation vector with the 6-pole rotor orientation. When installing a spare unit, technicians must ensure the drive project parameters match the 400V operational rating and torque curve to prevent unwanted overcurrent trips or position deviations.
Communication and System Integration
Physical wiring for the MDSKSAG071-03 utilizes industrial SpeedTec / Intercontec circular connectors. These connectors combine high-voltage motor power wiring and sensitive resolver signal lines into standard circular fittings designed for industrial dynamic automation environments.
System integration connects the motor directly to Lenze 400V/480V mains-operated servo drives. The built-in resolver feeds real-time rotational angle and speed feedback into the drive's control loop, supporting fast dynamic positioning, rotary indexing, and continuous dynamic motion processing across multi-axis production systems.
Diagnostics and Status Indication
Operational monitoring for the MDSKSAG071-03 relies on internal sensing and connected drive feedback. An embedded KTY84-130 / PTC thermal sensor tracks stator winding temperature, passing continuous monitoring signals to the drive controller to trigger thermal safety alarms before insulation damage occurs.
Detailed diagnostics are accessible via the drive interface using Lenze EASY Starter or Global Drive Control (GDC) software. Resolver alignment, speed measurement integrity, and thermal status can be monitored continuously through the host drive's software environment.
Replacement and Spare Part Considerations
When selecting a spare or replacement motor for part number 13314406, verify that the replacement shares the exact MDSKSAG071-03 model code. Crucial attributes to verify include the 071 frame size, 6-pole internal layout, 400V voltage category, and self-cooled natural ventilation design.
Because the unit uses SpeedTec circular connectors and an integrated resolver, matching wiring harnesses and drive feedback options are required. For system modernizations where legacy equipment is updated, recommended successor series such as Lenze MCS or m850 series motors can be considered, provided mechanical footprint and drive feedback parameters are appropriately matched.
