FEATURES
Energy saving
• Advanced optimum excitation control, which has been newly developed, provides a large starting torque while maintaining the motor efficiency under the conventional Optimum excitation control.
• The tuning function enables operation of other manufacturers’ induction motors and PM motors, which increases the use in the energy saving applications.
• With the 24 VDC external power supply, the input MC signal can be turned OFF after the motor is stopped, and turned ON before activating the motor. The inverter enables self-power management to reduce standby power.
Functions ideal for fans and pumps
• The rating can be selected between the two types (LD (light duty) or SLD (superlight duty)) depending on the load of the fan/pump to be used (multiple rating).
• The inverter can perform PID control of the motor operation and control the external equipment at the same time (PID multiple loops). The system cost can be reduced.
• By controlling the pumps connected in parallel (up to four pumps) by the PID control, water volume, etc. can be adjusted by one inverter (multi-pump function).
• Foreign matter on the impellers or fans of pumps can be removed by repeating forward/reverse rotation and stopping of the motor (cleaning function).
Security & safety
• Controls with safety functions can be easily performed (safety stop function).
• With the 24 VDC external power supply, the parameter setting and communication operation can be done without turning ON the main circuit power.
• The inverter is equipped with a temperature sensor, which outputs a signal when the internal temperature is high.
• The operating status immediately before the protective function is activated can be stored (trace function). A USB memory device and the inverter setup software (FR Configurator2) facilitate the trouble analysis at a separate location.
Compatibility with the environment
• A built-in noise filter (EMC filter) minimizes the EMI emitted from inverters.
• By installing a DC reactor (FR-HEL), which is available as an option, they can conform to the Architectural Standard Specifications (2013 revision) supervised by the Ministry of Land, Infrastructure, Transport and Tourism of Japan.
Easy setup & easy to use
• A USB host connecter (A type) is equipped. Parameters can be copied to commercial USB memory devices.
• Highly reliable and easily wired spring clamp terminals have been adopted for control circuit terminals.
