Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 15001177 (Model MDSKARS071-22) is an industrial AC asynchronous servo motor engineered for high-dynamic positioning, speed accuracy, and precise motion control within automated production environments. As part of the Lenze MDSKA product family, this surface-cooled motor combines the mechanical robustness of an induction motor with high-dynamic responsiveness. Designed around a standardized 071 frame size and winding code 22, the unit utilizes natural convection self-ventilation, eliminating the need for external cooling fans in dust-sensitive operating conditions across packaging, textile, and material handling systems.
Interfacing directly with Lenze drive controllers such as the 9300 Servo, 9400 HighLine, and i700 Cabinet Servo drives, the MDSKARS071-22 relies on an integrated high-precision resolver for closed-loop vector control, accurate torque generation, and position feedback. Putting a replacement motor into service requires matching the mechanical shaft dimensions, mounting flange profile, and resolver wiring to the original machine setup. Commissioning and parameterization are managed via Lenze engineering software tools like EASY Starter, Global Drive Control (GDC), or L-force Engineer, where standard motor catalog parameters can be loaded directly onto the connected drive. Support from ABC Industrial Parts can assist in verifying motor parameter sets and configuring drives during field replacement.
Operational monitoring and status feedback for the MDSKARS071-22 are executed through the connected drive controller. Continuous thermal protection is provided by built-in PTC thermistors or KTY sensors wired to the inverter's thermal contact input, while resolver feedback errors are actively evaluated by the drive's monitoring routines. Initial troubleshooting of motion anomalies or thermal faults should focus on verifying resolver cable integrity, motor terminal connections, and drive overtemperature parameters. Internal motor winding or resolver sensor faults cannot be serviced in the field; installing a tested exchange unit or utilizing repair services from ABC Industrial Parts provides a swift route to restoring machine operation.

Programming and Configuration
Drive integration and parameter setup for the Lenze 15001177 MDSKARS071-22 motor are performed through Lenze software tools, including EASY Starter, Global Drive Control (GDC), and L-force Engineer. These software suites contain motor catalog databases that allow technicians to select the MDSKA motor family with winding code 22, automatically populating default electrical and thermal values into the drive parameter set.
When replacing an existing motor or commissioning a new drive controller, uploading the pre-defined motor data ensures optimal closed-loop vector performance and correct current limits. Parameters governing resolver feedback ratios and PTC or KTY thermal sensor evaluation must be aligned within the drive setup to protect the motor during dynamic acceleration cycles.
Communication and System Integration
The Lenze MDSKARS071-22 integrates into high-dynamic motion axes via dedicated feedback and power connections to compatible drive systems, including the Lenze 9300, 9400 HighLine, and i700 cabinet servo drives. Motor position and speed feedback are transmitted through an integrated resolver mechanism, providing continuous analog position signals required for closed-loop vector control.
In addition to feedback signals, thermal protection wiring connects the motor's internal PTC thermistors or KTY temperature sensors directly to the drive controller. This physical signal integration allows the inverter to monitor motor winding temperatures continuously and safely interrupt operation before thermal limits are exceeded in demanding applications such as conveyor lines and packaging machinery.
Diagnostics and Status Indication
The MDSKARS071-22 asynchronous servo motor relies on drive-based monitoring for system diagnostics and fault reporting. Thermal protection is managed by the drive controller via continuous evaluation of the motor's internal PTC thermistor or KTY temperature sensor input, triggering overtemperature faults when operating limits are breached.
Resolver feedback integrity is monitored continuously by the connected Lenze drive controller. Errors such as resolver signal loss, wiring breaks, or feedback evaluation discrepancies generate dedicated fault codes on the drive interface, enabling targeted troubleshooting of motor cabling and feedback connections.
Replacement and Spare Part Considerations
Although the Lenze MDSKA motor series has been discontinued by the manufacturer, the 15001177 MDSKARS071-22 remains a critical drop-in replacement component for existing equipment. When installing a replacement unit, maintenance technicians must verify mechanical compatibility, specifically the frame size 071 flange profile, shaft dimensions, and keyway alignment.
Electrical and feedback compatibility requires matching the winding code 22 setup and verifying resolver signal wiring against the original installation. Following mechanical mounting, technicians should reload the catalog parameters using Lenze EASY Starter, GDC, or L-force Engineer software to ensure proper current limits, thermal trip thresholds, and resolver configuration on the host drive.
