Variable Speed Drive Solution — YASKAWA CIMR-G7A43P7 | G7 Series
Where This Product Is Used
The YASKAWA CIMR-G7A43P7 is a 3.7 kW (5 HP), 480 V three-phase AC inverter drive from the G7 Series — one of YASKAWA’s most field-proven general-purpose drive platforms. It is specified across a wide range of industrial applications where precise motor speed control, energy efficiency, and robust protection are non-negotiable.
- Pump & Fan Control — HVAC systems, cooling towers, water treatment plants, and building management systems rely on the G7 for smooth flow regulation and significant energy savings via variable torque operation.
- Conveyor & Material Handling — Logistics centers, packaging lines, and assembly conveyors use the G7’s V/f and vector control modes to maintain precise belt speed under variable load.
- Machine Tool & CNC Spindle Drives — The G7’s high carrier frequency and low-noise PWM output make it suitable for spindle motor control in milling, turning, and grinding machines.
- Compressor & Blower Drives — Industrial compressors and process blowers benefit from the G7’s built-in PID controller and auto-tuning for stable pressure regulation.
- Crane & Hoist Applications — With dynamic braking support and torque boost functions, the G7 handles regenerative loads in overhead crane and hoist systems.
- Food & Beverage Processing — Wash-down-adjacent environments use the G7 with appropriate enclosures for mixer, agitator, and conveyor drives.
- Water & Wastewater Treatment — Municipal pump stations and aeration blowers leverage the G7’s multi-pump control and sleep/wake functions.

Why Engineers Specify This Model
- Proven G7 Platform — The G7 series has accumulated millions of operating hours globally across heavy industry, making it a low-risk specification for critical processes.
- Flux Vector Control — Closed-loop vector mode delivers high starting torque (200% at 0 Hz with encoder feedback), essential for hoists, extruders, and servo-like positioning tasks.
- Built-in PID & Multi-Function I/O — Eliminates the need for external PLC logic in simple closed-loop applications such as pressure or flow control.
- Auto-Tuning — Rotational and stationary auto-tune routines reduce commissioning time and optimize motor performance without manual parameter calculation.
- Comprehensive Fault Diagnostics — Fault history log, output waveform monitoring, and DriveWizard PC software support rapid troubleshooting and predictive maintenance.
- Scalable Communication — Native Modbus RTU with optional fieldbus cards (DeviceNet, PROFIBUS-DP, EtherNet/IP) integrates seamlessly into existing SCADA and DCS architectures.
- Energy-Saving Functions — Energy-saving mode, sleep/wake, and DC injection braking reduce operating costs in pump and fan applications.

Application-Specific FAQ
Q: Can the CIMR-G7A43P7 run a 4 kW motor?
A: The G7A43P7 is rated for 3.7 kW in heavy-duty (HD) mode. Running a 4 kW motor is possible in normal-duty (ND) mode with the 9.2 A output rating, but verify the motor’s full-load current does not exceed this threshold. Consult YASKAWA’s drive sizing guidelines or contact us for confirmation.
Q: Is an encoder required for this drive?
A: No. The G7 operates in open-loop V/f or open-loop vector mode without an encoder. A PG feedback card is only required for closed-loop flux vector (zero-speed torque) applications.
Q: What fieldbus protocols are natively supported?
A: The drive natively supports MEMOBUS/Modbus RTU via the RS-485 port. DeviceNet, PROFIBUS-DP, and EtherNet/IP require optional SI-series option cards.
Q: Can this drive be used for single-phase input?
A: The CIMR-G7A43P7 is designed for three-phase 380–480 V input. Single-phase operation is not supported and will void the warranty.
Q: What is the typical lead time for this model?
A: In-stock units ship within 1–3 business days. For out-of-stock situations, lead time is typically 2–6 weeks depending on sourcing channel. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all drives sold. Extended warranty options are available on request.
