CIMR-G7A25P5 Yaskawa Variable Frequency Inverter 380 - 480VAC 2450/2500RPM
CIMR-G7A25P5 Description
The Yaskawa CIMR-G7A25P5 is a high-reliability, general-purpose vector control AC variable frequency drive (VFD) from the iconic Varispeed G7 series. Engineered for 200V class three-phase power supplies, this drive is specifically rated for 5.5 kW (7.5 HP) three-phase induction motors. It integrates advanced vector control technology and 3-level PWM output, delivering exceptional low-speed torque, precise speed regulation, and reduced electrical noise. With robust overload capacity, comprehensive protection mechanisms, and user-friendly operation, it is widely used in medium-duty industrial automation applications requiring stable, efficient motor control.
CIMR-G7A25P5 Key Features
- Dual Vector Control Modes: Supports V/f control, open-loop vector control, and closed-loop vector control to adapt to diverse application needs.
- 3-Level PWM Technology: Minimizes motor surge voltage, reduces electromagnetic interference (EMI), and extends motor winding and bearing lifespan.
- Strong Overload Capability: Handles 150% overload for 60 seconds (heavy-duty operation) and 200% overload for 0.5 seconds (peak load), ensuring reliability in demanding scenarios.
- Wide Frequency Range: Output frequency adjustable from 0.01 Hz to 400 Hz, suitable for both low-speed precision control and high-speed applications.
- Built-in PID Controller: Integrated process control function for automatic regulation of flow, pressure, temperature, or tension, ideal for pump, fan, and process control systems.
- Power Loss Ride-Thru: High-speed search and automatic restart function enables seamless recovery after momentary power interruptions, reducing production downtime.
- Comprehensive Protection: Equipped with overcurrent, overvoltage, undervoltage, overheating, input/output phase loss, motor overload, and stall prevention protections.
- Network Compatibility: Supports RS-485 communication for easy integration into industrial control networks; optional fieldbus modules available for expanded connectivity.
- User-Friendly Interface: 5-line backlit LCD keypad with parameter copy/backup functionality, supporting multiple languages for convenient operation and maintenance.
- Energy-Saving Design: Optimizes motor excitation current to reduce power consumption, especially in variable-load applications like pumps and fans.
