The provided document is a user guide for the Nidec Leroy-Somer Digistart D5 Digital Soft Starter.
Function Description:
The Digistart D5 is a digital soft starter designed to control the starting and stopping of motors. It offers a streamlined setup process with configuration profiles for common applications and a multi-language, easy-to-understand interface with descriptive option names and real-time performance graphs. The soft starter supports energy efficiency, being IE3 compatible and 99% energy efficient when running, and utilizes soft start technology to avoid harmonic distortion. It provides extensive input and output options, including remote control inputs (2 fixed, 2 programmable), relay outputs (2 fixed, 2 programmable), and an analog output. For advanced applications, optional features like smart cards, various communication options (DeviceNet, Ethernet/IP, Modbus RTU, Modbus TCP, Profibus, Profinet), and ground fault protection are available.
The soft starter can be started and stopped via digital inputs, a remote keypad, a communication network, a smart card, or scheduled auto-start/stop. It offers versatile starting and stopping options such as Scheduled Start/Stop, Adaptive Control, Constant Current, Current Ramp, Pump Clean, Timed Voltage Ramp Soft Stop, Coast To Stop, DC Brake, Soft Brake, and Reverse Direction. Customisable protection features include Motor Overload, Excess Start Time, Undercurrent/Overcurrent, Underpower/Overpower, Undervoltage/Overvoltage, Current Imbalance, Input Trip, and Motor Thermistor.
The soft starter can be connected to the motor in-line or inside delta (three-wire and six-wire connection). It automatically detects the motor connection type and calculates the correct inside delta current level. For models 0735C~1220C, dedicated bypass terminals allow the soft starter's protection and monitoring functions to work even when externally bypassed. Power factor correction can be controlled by connecting the PFC contactor to a programmable relay set to "Run".
