Yaskawa CIMR-JC4A0007BAA J1000 AC Drive

The Yaskawa CIMR-JC4A0007BAA is a compact AC drive from the J1000 series, designed for simple, cost‑effective motor speed control in applications up to 0.4 kW (0.5 HP). This drive accepts single‑phase 200‑240 V AC input and provides three‑phase output to control standard induction motors. It is ideal for small machines such as fans, pumps, conveyors, and other light‑duty automation equipment. The J1000 series is known for its ease of use, compact footprint, and robust performance, making it a popular choice for original equipment manufacturers and panel builders. The CIMR-JC4A0007BAA includes built‑in digital operator panel, analog and digital I/O, and Modbus communication.

Technical Specifications

Rated input: single‑phase 200‑240 V AC, 50/60 Hz (allowable fluctuation: -15% to +10%). Output: three‑phase 200‑240 V AC, 0.1‑400 Hz. Rated output current: 2.6 A continuous. Motor capacity: 0.4 kW (0.5 HP) for 200 V class motors. Overload capacity: 150% of rated output current for 60 seconds (150% for 60s, 200% for 3s for vector control). Control method: V/f control (with or without PG) and simple vector control. Frequency resolution: 0.01 Hz (digital reference) or 0.1% of max frequency (analog reference). Speed regulation: ±0.5% (for V/f) and ±0.2% (for vector). The drive includes 4 digital inputs, 1 digital output, 2 analog inputs (0‑10 V, 4‑20 mA), and 1 analog output (0‑10 V). Built‑in communication: Modbus RTU (RS‑485). Protection functions: overcurrent, overvoltage, undervoltage, overheating, ground fault, motor overload. Dimensions: 108 mm (H) × 68 mm (W) × 128 mm (D). Weight: approx. 0.7 kg. Operating temperature: -10 °C to +40 °C (with derating). Protection rating: IP20.

Key Features

• Compact, space‑saving design (occupies 68 mm width)

• Single‑phase input for easy installation in standard electrical panels

• Simple V/f control and sensorless vector control for improved low‑speed torque

• Built‑in digital operator panel with potentiometer for quick adjustments

• Modbus RTU communication for integration with PLCs and HMIs

• Removable terminal block for easy wiring

• Standard analog inputs (0‑10 V, 4‑20 mA) and outputs

• Dynamic braking circuit (external resistor required)

• Pre‑programmed application macros (fan, pump, etc.)

• CE, UL, cUL certified, RoHS compliant

Control and Operation

The J1000 drive offers two primary control modes: V/f control (for general purpose applications) and simple vector control (for applications requiring better low‑speed torque). The built‑in digital operator has a 4‑digit LED display and five buttons for run/stop, programming, and navigation. The drive supports both keypad and terminal block start/stop. Acceleration and deceleration times are independently adjustable from 0.0 to 6000.0 seconds. The drive also features a built‑in PID controller, allowing direct connection of a process feedback sensor (e.g., pressure or flow) for closed‑loop control without an external controller. The Modbus RTU interface allows reading/writing of drive parameters and monitoring of output frequency, current, and status.

Applications

The CIMR-JC4A0007BAA is suitable for small machinery such as lab exhaust fans, small water recirculation pumps, conveyor drives in packaging lines, agitators and mixers, and HVAC fan coils. The compact size allows direct panel mounting. It is also used in OEM equipment where a simple variable speed drive is needed without complex programming. The analog inputs can be connected to a 0‑10 V speed potentiometer or a 4‑20 mA signal from a PLC.

Installation and Wiring

Mount the drive vertically on a DIN rail or directly on a panel using M4 screws (4 required). Ensure sufficient clearance (≥30 mm above and below) for cooling airflow. Connect single‑phase power to terminals L1 (R) and L2 (S). Connect the three‑phase motor to terminals U, V, W. Connect the ground terminal to the panel ground. For control wiring, use shielded cables for analog signals. The digital inputs can be configured for forward/stop, reverse/stop, multi‑speed selection, and external fault. The drive includes an internal braking transistor; for dynamic braking, connect an external braking resistor between terminals B1 and B2 (or B1 and B+). All external wiring must comply with local codes. Never connect power to output terminals U, V, W.

Maintenance and Troubleshooting

The drive requires no routine maintenance beyond periodic cleaning of the cooling fan and ventilation slots (check every 6‑12 months). The drive has a fault memory that stores the last 10 faults. Common fault codes include: OC (overcurrent), OV (overvoltage), UV (undervoltage), OH (overheat), and GF (ground fault). Use the digital operator to view the fault history. The drive can be reset by cycling power or via a digital input (if configured). If the drive repeatedly trips, check the motor insulation resistance, cable length, and load conditions. The cooling fan has an expected life of approximately 40,000 hours; replace the fan when it becomes noisy or fails.

Conclusion

The Yaskawa CIMR-JC4A0007BAA J1000 AC drive delivers reliable, simple motor speed control in a compact package. Its single‑phase input, 0.4 kW rating, and built‑in operator panel make it a practical choice for small industrial machines and fans. The Modbus RTU capability and analog I/O allow easy integration into automation systems.
