DescriptionSiemens MICROMASTER 430 Frequency Inverter | 7.5 kW - 250 kW
OverviewThe MICROMASTER 430s are a range of 3AC-frequency inverters for controlling the speed of three phase AC motors. The various models available range from the 7,5 kW input to the 250 kW input.The MICROMASTER 430 is especially well suited for use with pumps and ventilators when used with its factory set functions and settings.The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A special pulse-width modulation method with selectable Pulse frequency permits quiet motor operation. Comprehensive protective functions provide excellent inverter and motor protection.
Key FeaturesEasy installation Easy commissioning Rugged EMC design Can be operated on IT line supplies Fast repeatable response time to control signals Comprehensive range of parameters enabling configuration for a wide range of applications Simple cable connection Output relays Analog outputs (0 – 20 mA) 6 Isolated and switchable NPN/PNP digital inputs 2 Analog inputs:- • AIN1: 0 – 10 V, 0 – 20 mA and -10 to +10 V- • AIN2: 0 – 10 V, 0 – 20 mA The 2 analog inputs can be used as the 7th and 8th digital inputs BiCo technology Modular design for extremely flexible configuration High switching frequencies for low-noise motor operation Detailed status information and integrated message functions External options for PC communications, Basic Operator Panel (BOP-2)
Performance CharacteristicsU/f control- • Linear U/f control with flux current control (FCC)for improved dynamic response and motor control- • Multiple point U/f control Automatic restart Flying restart Slip compensation Fast Current Limitation (FCL) for trip-free operation Motor holding brake Built-in DC injection brake Compound braking to improve braking performance Setpoint input via:- • Analog inputs- • Communication interface- • Motorized potentiometer- • Fixed frequencies Ramp function generator- • With smoothing- • Without smoothing Technology controller (PID) parameter set switch-over- • Motor data sets (DDS)- • Command data sets and setpoint sources (CDS) Rating for operation with variable torque (VT) Free Function Blocks
PROFIBUS Communications ModulePump & Fan Features:- • Motor Staging (Control of additional drives via output relay)- • Energy Saving Mode- • Hand / Auto (manual / automatic) with BOP-2- • Belt failure detection (e.g. detects if pumps have run dry)- • Bypass
Protection characteristicsOvervoltage/undervoltage protection Overtemperature protection for the inverter Ground fault protection Short-circuit protection I²C thermal motor protection PTC/KTY for motor protection
