SCHNEIDER ELECTRIC ATV71LD10N4Z Altivar Lift Elevator Variable Speed Drive

Overview

The SCHNEIDER ELECTRIC ATV71LD10N4Z is an elevator-specific variable speed drive from Schneider Altivar Lift ATV71 series. The SCHNEIDER ELECTRIC ATV71LD10N4Z is rated for 4 kW / 5 HP, 380–480 V three-phase supply, and supports both asynchronous and synchronous elevator motors with encoder feedback. It delivers smooth speed regulation, precise landing control and dedicated lift safety logic for passenger and freight elevators. The SCHNEIDER ELECTRIC ATV71LD10N4Z comes with integrated EMC filter and built-in heat sink, and the suffix Z indicates it is equipped with the basic 7-segment keypad instead of the graphic terminal. It is a discontinued commonly stocked spare for elevator modernization and on-site maintenance.

Features

The SCHNEIDER ELECTRIC ATV71LD10N4Z adopts high-performance flux vector control algorithm to achieve low-speed high-torque output and stable ride comfort. It includes dedicated elevator functions such as S-curve acceleration and deceleration, brake sequence control, load torque compensation and landing positioning logic. The SCHNEIDER ELECTRIC ATV71LD10N4Z supports Modbus and CANopen communication for elevator group control and remote monitoring. It integrates comprehensive protection functions including overcurrent, overvoltage, undervoltage, motor overload, encoder fault and overspeed detection. The SCHNEIDER ELECTRIC ATV71LD10N4Z complies with EN 12015 and EN 12016 elevator EMC standards without requiring an external filter. Parameter backup and upload can be completed via Schneider SoMove software or simple loader.

Specs

Device Type: Elevator dedicated variable speed drive Model: SCHNEIDER ELECTRIC ATV71LD10N4Z Series: Altivar Lift ATV71 Rated Power: 4 kW (5 HP) Supply Voltage: 380 V ~ 480 V three-phase Control Mode: Flux vector control, encoder feedback Communication: Modbus, CANopen Built-in: EMC filter, heat sink Keypad: 7-segment basic display terminal Certification: CE, UL, CSA Protection Grade: IP20 Operating Temperature: -10°C ~ +50°C Application: Passenger elevator, freight elevator, elevator renovation, lift control cabinet

Principle

The SCHNEIDER ELECTRIC ATV71LD10N4Z receives run commands and floor position signals from the elevator main controller. It outputs adjustable frequency and voltage three-phase power to the traction motor. The encoder feeds back real-time speed and position to the drive for closed-loop regulation. The SCHNEIDER ELECTRIC ATV71LD10N4Z coordinates with the brake contactor to manage the opening and closing sequence of the holding brake, ensuring smooth start and accurate leveling. It continuously monitors operating status and triggers safety shutdown and fault codes when abnormal conditions occur.

Applications

The SCHNEIDER ELECTRIC ATV71LD10N4Z is widely used as traction machine drive for passenger elevators and freight elevators in commercial buildings, residential buildings and industrial plants. It serves stable speed regulation and safety control for modernized lift systems. The SCHNEIDER ELECTRIC ATV71LD10N4Z applies to spare stock and emergency replacement of legacy Altivar Lift elevator drive assemblies. It also supports elevator control cabinet renovation and parameter setting re-tuning projects.
