Overview
The Lenze M1110SB is a constant-horsepower variable frequency drive designed for precise motor speed and torque control in industrial automation and motion control applications. Part of the MC Series lineup, this 1HP drive delivers reliable performance with Enhanced Torque System (ETS) technology and a compact, rugged steel enclosure rated NEMA 1 for factory floor environments.
Key Features
- Enhanced Torque System (ETS): Highly efficient sine coding algorithm with auto-voltage boost delivers maximum starting and accelerating torque even under fluctuating load conditions
- Rugged NEMA 1 Enclosure: Durable steel construction withstands daily factory floor conditions
- 16-Character LCD Display: Easy-to-read keypad interface with Start, Stop, Up, Down, Forward/Reverse, Program/Run, Auto/Manual, and Enter buttons for intuitive operation
- Built-in Motor Protection: UL-approved thermal overload provides full motor protection
- Programmable I/O: Extensive programmable functions support simple ramped start/stop and speed control to advanced PID set-point control applications
- Quick Start Presets: Factory presets and English-language programming via touch keypad reduce commissioning time
