Pump & Fan Drive Solution – YASKAWA CIMR-L5JJ4011 | L5 Series
Where This Product Is Used
The YASKAWA CIMR-L5JJ4011 is a 15 kW (20 HP), 400 V class variable frequency drive from the YASKAWA L5 Series, purpose-engineered for variable-torque loads in building services and light industrial environments. Typical deployment scenarios include:
- HVAC Systems – Supply and return air fans in commercial buildings, AHUs, and rooftop units where energy savings through speed control are critical.
- Pump Stations – Centrifugal water pumps, booster pumps, and chilled-water circulation loops requiring smooth ramp-up and pressure regulation.
- Cooling Towers – Fan speed modulation to maintain condenser water temperature setpoints.
- Industrial Ventilation – Exhaust and supply fans in manufacturing plants, clean rooms, and process facilities.
- Water Treatment – Aeration blowers and transfer pumps in municipal and industrial water/wastewater plants.
- OEM Machinery – Embedded in packaged pump skids, fan arrays, and compressor systems where compact footprint and reliable V/f control are required.

Why Engineers Specify This Model
- Variable-Torque Optimized: The L5 Series is factory-configured for fan and pump loads, delivering up to 30–50% energy savings versus across-the-line starters through affinity-law speed reduction.
- Proven Reliability: YASKAWA’s L5/G5 platform has millions of installed units globally across HVAC and water infrastructure — a benchmark for mean time between failures (MTBF) in the VFD industry.
- Built-in PID Control: Closed-loop pressure or flow control without an external PLC, reducing panel complexity and BOM cost.
- Modbus RTU Native: Direct integration with BMS/SCADA systems via RS-485 without additional gateways.
- Dynamic Braking Transistor: Enables fast deceleration for applications requiring controlled stop cycles.
- Auto-Restart & Fault Ride-Through: Minimizes unplanned downtime in critical infrastructure applications.
- Compact Panel Footprint: Optimized chassis dimensions for retrofit into existing MCC or control panel enclosures.
Complete System Bill of Materials
For a fully commissioned CIMR-L5JJ4011 drive installation, engineers typically specify the following complementary components:
- Input Line Reactor – 3% impedance AC reactor for harmonic mitigation and protection against line transients
- EMC Input Filter – Class C2/C3 filter for CE compliance in sensitive environments
- Dynamic Braking Resistor – External resistor for high-inertia load deceleration (if duty cycle exceeds internal transistor rating)
- Output dV/dt Filter – Motor protection filter for long cable runs (>50 m) to prevent winding insulation stress
- Bypass Contactor Assembly – Manual or automatic bypass for maintenance continuity in critical HVAC systems
- Remote Operator Panel – YASKAWA JVOP-182 or compatible remote keypad for panel-door mounting
- RS-485 Communication Cable – Shielded twisted-pair for Modbus RTU BMS integration
- Fused Disconnect Switch – Upstream protection per NEC/IEC installation requirements
Compliance & Industry Standards

Application-Specific FAQ
Q: Can the CIMR-L5JJ4011 control a 15 kW pump motor directly?
A: Yes. The drive is rated for 15 kW normal-duty (variable torque) loads. For constant-torque or heavy-duty applications at 15 kW, verify the output current against your motor’s FLA and consider the next frame size up.
Q: Is this drive compatible with BACnet or LonWorks BMS systems?
A: The CIMR-L5JJ4011 natively supports Modbus RTU via RS-485. BACnet/IP or LonWorks integration requires an optional YASKAWA SI-B3 or third-party protocol gateway.
Q: What is the replacement/equivalent current-generation YASKAWA model?
A: The functional successor is the YASKAWA GA500 (CIPR-GA50B4011ABB) or GA700 series for higher-performance vector control requirements. Konmask can supply both legacy and current-generation units.
Q: Can I use this drive for a constant-torque conveyor application?
A: The L5 Series is optimized for variable-torque (fan/pump) loads. For constant-torque conveyors or hoists, the YASKAWA A1000 or GA700 with open-loop vector control is the recommended specification.
Q: What is the warranty and return policy?
A: Please contact support@konmask.com for current warranty terms applicable to your order. We offer pre-shipment inspection reports on request.
