Description
Optimizing motor speed and torque, the Mitsubishi Electric FR-CS84-230-60 functions as a highly compact three-phase variable frequency drive designed for precise control of 11 kW induction motors. Engineered within the space-saving FR-CS80 micro-drive series, this inverter provides reliable, high-torque motor control with built-in magnetic flux vector control capabilities, making it ideal for standard industrial drive applications requiring high dynamic response and robust electrical protection.
Features
- Optimized for 11 kW (15 HP) motor capacities with a continuous rated capacity of 17.5 kVA.
- Robust dual overload rating profile handling 150% of rated current for 60 seconds and 200% for 0.5 seconds.
- Accepts wide AC input voltage ranging from 380 V to 480 V (fluctuates safely between 325 V and 528 V).
- Equipped with an advanced cooling system utilizing forced air cooling to maintain thermal stability.
- Compact physical footprint engineered for close-mounting configurations inside industrial control enclosures.
Applications
- Industrial conveyor lines and material handling machinery.
- Centrifugal pumps and fan flow regulation systems.
- High-speed packaging systems and automatic sorting equipment.
- Machine tool spindles and manufacturing auxiliary drives.

Empirical Engineering Insights
Alternative Models & Compatibility
The FR-CS80 series offers a highly streamlined, physical footprint compared to the high-end FR-E800 or legacy FR-D700 series. When upgrading to the FR-CS84-230-60 from a legacy drive, confirm control logic and parameter settings, as the micro-drive series utilizes simplified parameter groups optimized for core applications.
Application Pitfalls & Engineering Notes
Thermal management is a critical consideration for 11 kW micro-drives. When mounting multiple FR-CS84-230-60 units in a single electrical cabinet, ensure vertical alignment with at least 50 mm of top/bottom clearance. Continuous low-speed operation under heavy load can cause motor overheating; consider using an external cooling fan on the motor or setting parameter limits to prevent prolonged operation below 6 Hz.
Commissioning & Wiring Tips
To minimize electromagnetic noise, run all control wiring (analog signals, start/stop commands) using shielded twisted-pair cables separate from high-power line cables (R/L1, S/L2, T/L3 and motor connections U, V, W). Ensure the shield is terminated only at the drive's dedicated grounding point to avoid ground loops.
Installation Guidelines
CRITICAL WARNING
Disconnect all main power supplies before starting wiring work. After turning off the input power, wait at least 10 minutes for internal capacitors to fully discharge, and confirm that the onboard charge lamp is completely extinguished before touching any electrical terminals.
1
Mount the inverter vertically onto a flat, heat-resistant, non-combustible vertical wall or panel surface.
2
Connect the 3-phase AC input power line to terminals R/L1, S/L2, and T/L3. Never connect power lines to output terminals.
3
Securely connect the three-phase motor leads to output terminals U, V, and W.
4
Establish a high-integrity, low-impedance connection from the drive's grounding terminal to the protective earth (PE) system.
