The programme is parametric and can easily bemodified by the end user.- Various chopper configurations can be selected by the user, without the need forhardware modifications.- Future technological updates are made easy for the user.The communication protocol will continue to evolve, thereby offering increas-ing possibilities of interaction and expansion. For this reason, the Zapimosfamily offers a standard dialogue mode with external systems. This allowsinterfacing withcommercially available machines. Zapi can offer a range of individually designedConsole Software with various features and prices.- SEM-Zero meets the requirements of (IP54). This provides excellent protectionagainst spray (water, acid.), and against the ingress of dust or small foreign particles.Access to the control logic is very simple, and allows simple substitution or replace-ment.- The SEM-Zero family of Choppers are suitable for operating on DC voltages from 24to 36V inclusive, with maximum armature current up to 200A.The choppers may be used to control DC Separately Excited Motors with powerratings up to 2.0kW.ACLZP0CB - SEM-ZERO - User manualPage 4 of 382 GENERAL CHARACTERISTICS2.1 TECHNICAL SPECIFICATIONChopper for Separately Excited DC motors ................................................... 0.5 ÷ 2.0kWRegenerative Braking.Voltage Range ................................................................................................. 24-36VDCMaximum Field Current (all the versions) ................................................................. 35 AArmature Switching Frequency ............................................................................... 16kHzField Switching Frequency ........................................................................................ 1kHzMaximum Ambient temperature ............................................................................. + 40°CMinimum Ambient temperature ................................................................................-30°CMaximum temperature of Chopper ........................................................................ + 80°CVERSIONSMAXIMUM CURRENTBOOSTER CURRENTVOLTAGE DROP INFULL CONDUCTION0.23V at 50A, 25°C0.23V at 50A, 25°C24 / 36V24 / 36V150A (3')200A (2')180A (10'')230A (10")2.2 CONTROL UNITS2.2.a Microswitches- Microswitches should have a contact resistance lower than 0.1Ω, and a leakagecurrent lower than 100 µA.- When full load current is being drawn, the voltage drop across the Key Switch contact must be lower than 0.1V.- If an Electromagnetic Brake is used, the Handle Microswitch must be able to operatethe Brake Coil.- The Microswitches send a voltage signal to the microprocessor when an operatingrequest (running) is made.ACLZP0CB - SEM-ZERO - User manualPage 5 of 38 [ Pobierz całość w formacie PDF ]
