Lenze TT140 – Tension Control Module | Drive-Based Closed-Loop Winding Controller
Engineering Background: Precise web tension is critical in converting, printing, and textile machinery. Uncontrolled tension causes web breaks, wrinkling, and scrap. The Lenze TT140 is a dedicated tension control technology module that integrates directly into the Lenze 8400 / E94 drive platform, delivering closed-loop tension regulation without an external PLC or standalone controller.
Product Positioning: The TT140 is engineered for OEMs and system integrators who require deterministic, drive-native tension control in winding, unwinding, and dancer-regulated web-handling lines. It eliminates external hardware, reduces cabinet footprint, and shortens commissioning time.

Engineering Advantages
- Drive-native integration: Eliminates external tension controller hardware and associated wiring
- Taper tension algorithm: Automatically compensates roll diameter growth/reduction for consistent tension throughout the reel
- Dual feedback modes: Supports both load-cell and dancer-roll feedback; switchable at runtime
- Rapid commissioning: Pre-parameterized function blocks within Lenze Engineer software
- Deterministic response: Tension loop executes within drive scan cycle for minimal latency
- Compact footprint: Module slot installation; no additional DIN rail space required
System Architecture & Signal Flow
The TT140 plugs into the technology module slot of a compatible Lenze 8400 or E94 series inverter. Tension feedback (load cell mV/V or dancer potentiometer 0–10 V) is wired to the drive’s analog input. The TT140 firmware processes the feedback signal, computes the tension error, and outputs a corrective torque/speed setpoint to the drive’s motor control loop. Diameter calculation is performed internally using a configurable ramp model or an optional encoder-based actual-diameter measurement. Fieldbus setpoints (tension reference, enable, mode select) are exchanged via the host drive’s communication interface.

Technical FAQ
Q: Which Lenze drive series is the TT140 compatible with?
A: The TT140 is designed for the Lenze 8400 StateLine/HighLine/TopLine and E94 series inverters that feature a technology module slot. Confirm slot availability in your drive’s hardware manual before ordering.
Q: Can the TT140 work with both load cells and dancer rolls?
A: Yes. The module supports both feedback types. Selection is made via parameter setting in Lenze Engineer software.
Q: Is an external PLC required?
A: No. The TT140 runs entirely within the drive. A PLC or HMI may still be used for setpoint and mode commands via fieldbus, but the tension control loop itself is drive-internal.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. Out-of-stock items are quoted individually.
Q: Do you provide a datasheet or wiring diagram?
A: Yes. Contact support@konmask.com with your order reference and we will supply available documentation.
