VARIATOR

Product catalog summary

Overview: The document provides detailed information about the Verlinde Variator stepless speed control systems, specifically designed for crane applications. These systems, VARIATOR LM for hoisting and VARIATOR TM for travelling, utilize advanced inverter and vector control technology to enhance crane productivity, safety, and reliability.

Specifications: The systems are engineered to meet the requirements of both new and existing cranes, offering excellent torque and brake control management. They feature robust mechanical construction and user interfaces suitable for a wide range of crane applications. The systems support a frequency control range of 0-60Hz and offer speed control accuracy of ±2% of nominal speed at a speed range of 20-100%.

Key Features: The VARIATOR systems provide stepless speed control, which results in significant benefits such as reduced maintenance costs, improved reliability, and enhanced safety through easier load handling and minimized load swing. Additional safety is provided by a separate and independent hoisting speed supervision control.

Control and Protection: The systems include features like modulation sine wave PWM, open loop flux vector control, and various protection mechanisms such as stall prevention, motor overload protection, inverter overload protection, and short circuit protection. They also have ambient condition specifications, including operating temperatures from -10°C to +50°C and vibration resistance conforming to IEC standards.

Performance and Installation: The VARIATOR LM utilizes open loop flux vector control with type-tested motors and a hoisting speed feedback system. The NOVA speed supervision unit ensures safety by monitoring the actual speed of the hoisting motor and stopping motion in case of overspeed or other errors. The systems are designed for easy installation and quick start-up due to standardized user interfaces and setup functions.

Power and Output: The document provides detailed power and output specifications for different voltage series, including overloadability and maximum output voltage. The systems are capable of handling various power outputs and currents, ensuring flexibility for different crane applications.

Global Support: Verlinde operates globally, providing customer service and solutions for material handling processes. Their experts offer installation and service agreements to ensure a prompt return on investment.
