Altistart 48 Enclosed Altistart 48 Soft Starters Page 6 Introduction

6 Altistart 48 soft starters for asynchronous motors Introduction Product (continued) Advanced soft starter performance Exclusive Torque Control System (TCS) patented by Schneider Electric Constant control of the torque supplied to the motor during acceleration and deceleration periods (significantly reducing pressure surges) Adjustments for ramp and the starting torque The soft starter can be bypassed using a contactor at the end of the starting period while maintaining electronic overload protection (bypass function) Wider frequency tolerance for generator set (source) power supplies Intelligent machine and motor protection Built-in motor thermal overload protection Processing of information from PTC thermal probes Monitoring of the starting time Protection against underloads and overcurrents during continuous operation Extended I/O functions for integration into control systems 4 logic inputs, 2 logic outputs, 3 relay outputs, and 1 analog output Pull-apart terminal connectors Function for configuring a second set of motor parameters and easy-to-adapt settings Display of electrical values, running conditions, and operating time RS-485 serial link for connection to a Modbus system Communication The ATS48 soft starter can be connected directly to a Modbus system using an RJ45 connector. It communicates over the RS-485 serial link (2-wire) using the Modbus system's RTU protocol. The communication function provides access to the configuration, adjustment, control, and signalling functions of the soft starter. The ATS48 soft starter can be connected to other buses or networks using the communication modules and accessories below. 4 5 3 4 3 ATS48 6 1 2 1 DeviceNet communication module ( LUFP9 ) 2 Modbus Systems hub (LU9GC3) 3 Modbus Systems drop cable (VW3A8306R pp ) 4 Line terminator (VW3A8306RC) 5 Modbus Systems splitter cable (VW3A8306TF pp ) 6 To other buses or networks Example Altistart 48 communication network Performance Protection Integration
