Product Introduction & Supply Chain Strategy
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. The Lenze ESMD113L4TXH509 is an 11 kW (15 HP) 3-phase AC variable frequency drive designed for precise speed control in pumps, fans, conveyors, and general material handling machinery.
Securing this unit as New Surplus offers vital protection against costly motor control downtime. Because the Lenze SMD series has reached legacy status, an unexpected drive failure often forces entire panel redesigns to accommodate newer drive footprints and programming structures. Carrying a genuine, unaged ESMD113L4TXH509 unit on-site ensures zero lead-time replacement, keeps your control cabinet wiring intact, and minimizes total cost of ownership (TCO).
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
High-Voltage DC Bus Danger
Disconnect main AC power and wait at least 3 minutes for internal DC bus capacitors to fully discharge before servicing. Measure DC voltage across terminals UG+ and UG- to confirm voltage is below 50 V DC.
- Perform Lock-Out/Tag-Out (LOTO) on the main 400/480 V AC supply circuit breaker.
- Put on an ESD-grounded wrist strap before opening terminal covers or handling internal memory chips.
- Label all power leads (L1, L2, L3, U, V, W), braking resistor lines, and control terminal block wires.
- Remove the Electronic Programmable Module (EPM) memory chip from the old drive to prepare for parameter transfer.
Stage 2: Removal
- Disconnect the main AC power input lines (L1, L2, L3) and motor output lines (U, V, W) from the heavy-duty power terminal block.
- Unplug the control terminal strips (digital I/O, analog reference, relay connections).
- Loosen the four enclosure mounting screws securing the heatsink frame to the cabinet backplate.
- Carefully unmount the drive, taking care not to damage neighboring wiring ducts or line chokes.
Stage 3: Installation (Clone & Seat)
- Mount the new ESMD113L4TXH509 vertically on the enclosure panel, ensuring a minimum clearance of 100 mm (4 inches) above and below for forced-air heat dissipation.
- Insert the original EPM memory chip into the designated EPM slot on the front of the new drive to instantly clone all parameter settings.
- Reconnect the motor cable (U, V, W) and main supply cable (L1, L2, L3) to their respective power terminals. Torque screw terminals according to manufacturer specifications.
- Secure the PE earth ground conductor directly to the drive’s grounding stud. Reattach all control terminal strips.
Stage 4: Power-On & Testing
- Apply 400/480 V AC supply power to the unit.
- Verify the front LED display lights up without showing fault codes (e.g.,
F.11orF.12). - Issue a low-frequency run command (5 to 10 Hz) and verify correct motor rotation direction, smooth acceleration, and normal output current readouts.

Firmware/Software Versions & Upgrade Notes
- EPM Memory Cloning: Parameter retention on the ESMD113L4TXH509 relies on Lenze’s pluggable Electronic Programmable Module (EPM). All drive parameters (ramp times, motor data, V/f curves) are stored on this removable chip.
- EPM Programmer Compatibility: Parameters can be copied using a handheld Lenze EPM Programmer or transferred directly by moving the physical EPM chip from the existing drive to the replacement unit.
- Firmware Notes: Ensure the hardware revision of the replacement unit supports your application’s control mode. Swapping EPM chips between identical ESMD model numbers is fully backward and forward compatible.
Frequently Asked Questions (FAQ)
Q: Is this Lenze ESMD113L4TXH509 drive brand new or refurbished?
A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
Q: Why choose New Surplus over a lower-cost refurbished Lenze drive?
A: Refurbished drives often contain degraded DC bus electrolytic capacitors and thermally stressed IGBT power modules. A failed drive can trigger motor winding damage or cause days of unscheduled production outage. Purchasing New Surplus guarantees factory-fresh internal components and full operational lifespan.
Q: Do I need software to configure this drive during a replacement?
A: No software or laptop connection is required if you have the original drive’s EPM chip. Simply unplug the EPM chip from your old drive and insert it into the new to clone 100% of your parameter configurations immediately.
Q: Can this drive accept both 400 V and 480 V AC main inputs?
A: Yes. The supports a broad 3-phase input supply range from 320 to 528 V AC, making it fully compatible with both European 400 V and North American 480 V industrial power grids.
Q: What warranty coverage is provided with this unit?
A: Every Lenze drive comes backed by a comprehensive 1-year functional replacement warranty, complete with serial number tracking and pre-shipment electrical testing verification.
