The ZONCN Z2400-3R7G/5R5P is a high-performance variable frequency drive (VFD) from the Z2400 series, designed for industrial motor speed and torque control. Rated at 3.7kW in constant torque (G-type) and 5.5kW in variable torque (P-type) operation, this compact inverter delivers reliable performance for a wide range of industrial applications including air compressors, fans, pumps, conveyors, and general-purpose motor drives.
Dual Control Modes – Supports SFVC and V/F control. Vector mode ensures precise speed/torque; V/F mode offers simple, reliable operation.
High Starting Torque – In vector mode, G-type delivers 150% rated torque at 0.5 Hz for heavy-duty starts.
Strong Overload Capacity – G-type: 150% rated current for 60 s; 180% for 3 s.
Wide Speed Range & High Accuracy – 1:100 speed range with ±0.5% speed stability.
Wide Frequency Output – 0–320 Hz in vector mode; 0–3200 Hz in V/F mode, covering standard drives and high-speed spindles.
Built-in PID & RS485 – Onboard PID enables closed-loop control; RS485 with Modbus-RTU supports PLC, HMI, and SCADA integration.
AVR – Maintains stable output voltage during mains fluctuations.
Compact & Easy to Install – Space-saving design, removable control panel, and optional built-in EMC filter.

Q1: What is the difference between G-type and P-type ratings?
G-type is designed for constant torque loads (conveyors, compressors, extruders) with heavy-duty overload capability. P-type is for variable torque loads (fans, pumps) with lower overload requirements. The Z2400-3R7G/5R5P supports both ratings in one unit.
Q2: Can this VFD run a permanent magnet (PM) motor?
Yes. The Z2400 series supports PM motor control. Please confirm the specific PM motor parameters with us before ordering.
Q3: What communication options are available?
Standard RS485 with Modbus-RTU protocol. This allows integration with PLC, HMI, and SCADA systems for remote monitoring and control.
Q4: Does it come with a built-in EMC filter?
The standard model does not include a built-in EMC filter. However, an EMC filter version is available as an option. We recommend using an external EMI filter on the input side for optimal electromagnetic compatibility.
Q5: What is the warranty period?
We offer a standard 12-month warranty. Extended warranty options are available. Please contact us for details.
Q6: Can you provide technical support and commissioning guidance?
Yes. We provide 24/7 online technical support, remote commissioning assistance, and comprehensive after-sales guidance.
Q7: Is this model suitable for air compressor applications?
Absolutely. The Z2400 series is specifically optimized for air compressor applications, with simple terminal design for easy installation and compatibility with ZONCN HMI controllers.
