Yaskawa CIMR-F7Z4045 Varispeed F7S Series 45 kW AC Drive
The Yaskawa CIMR-F7Z4045 is a high-performance AC drive from the Varispeed F7S series of frequency converters, engineered for precise speed regulation and torque control of three-phase AC motors. This 45 kW drive is designed to convert fixed frequency AC mains power into adjustable voltage and frequency output, enabling variable speed control of pumps, fans, compressors, conveyors, and other industrial machinery. The CIMR-F7Z4045 is part of Yaskawa comprehensive range of AC drives known for their reliability, efficiency, and advanced control features, suitable for heavy-duty industrial applications.
Technical Specifications
The Yaskawa CIMR-F7Z4045 operates on three-phase 380-480 V AC input voltage, compatible with mainstream industrial power architectures. The maximum applicable motor capacity is 45 kW, with a rated output capacity of 69 kVA and rated output current of 91 A, enabling stable driving of medium and high-power AC motors in demanding industrial scenarios. The output frequency range is adjustable from 0 to 400 Hz, with overload capacity of 150% for 60 seconds for enhanced performance during demanding operations. The standard protection level is IP20, with optional IP21/IP54 protection kits available to meet installation needs in control cabinets or light dust environments.
Control Modes and Performance
The CIMR-F7Z4045 supports multiple control modes including V/F control and sensorless vector control (without encoder), allowing flexible switching according to load types and adaptation to multiple working conditions. The drive features Yaskawa advanced 3-level control technology, energy-saving vector performance, and accurate torque protection. Low-speed torque boosting function enables stable torque output even at low speeds, making the drive suitable for constant torque loads such as cranes and conveyors. The drive optimizes PWM modulation technology with intelligent air cooling design, resulting in low operating noise suitable for applications with high quietness requirements.
Communication and Protection
The CIMR-F7Z4045 is equipped with standard RS-422/485 communication interface, with optional industrial bus cards such as PROFIBUS-DP and DeviceNet for system integration. Built-in multiple protection functions including overload protection, overvoltage protection, undervoltage protection, and overtemperature protection quickly respond to circuit abnormalities, safeguarding motor and inverter safety. The working temperature range extends from -10°C to 40°C, with stable temperature resistance capable of adapting to temperature fluctuations in most industrial sites. The drive supports both base installation and DIN rail mounting, providing flexible installation options for different distribution cabinet layout requirements.
Applications
The Yaskawa CIMR-F7Z4045 is deployed in industrial applications requiring variable speed control of 45 kW motors. Typical applications include pump control for flow regulation in water treatment and irrigation systems, fan control for air handling and ventilation systems, conveyor systems in material handling, and compressor control for industrial gas and refrigeration systems. The drive is also used in packaging machinery, textile equipment, injection molding machines, CNC machine tools, and any industrial application where adjustable motor speed provides energy savings and process control benefits compared to fixed-speed operation.
