MX2-ZV1 Frequency Converter Inverter| 200% Torque at 0.5Hz, Compact Power for Global Precision Drives
MX2-ZV1 Frequency Converter Overview
The MX2-ZV1 series is high-performance compact inverter designed for global small-to-medium industrial applications. With power coverage from 0.1kW to 18.5kW, it supports single-phase 200V and three-phase 200V/400V grids, adapting seamlessly to 50/60Hz global power systems. Equipped with sensorless vector control, it delivers 200% starting torque at 0.5Hz, making it ideal for both constant-torque loads like conveyors and variable-torque loads such as fans and pumps.

Application Scenarios
Small Electronics Assembly
Micro feeder axes for SMT pick-and-place machines, light-load conveyor rollers for PCB inspection equipment. The 0.1kW power is perfect for small loads with compact size fitting inside equipment enclosures.
Laboratory & Medical Applications
Speed control for reagent mixers and small centrifuges. Compatible with local single/three-phase grids with ±0.01% speed accuracy ensuring consistent mixing/centrifugation.
Packaging Workshops
Labeling axes for compact labelers, light-load conveyors for packaging machines. Multi-speed settings allow quick switching of labeling/conveying speeds.
Food Processing
Hot air fans for small coffee roasters, micro vibratory screens for dried fruit sorters. Wide temperature range handles roastery heat effectively.
Horticultural Equipment
Low-power pumps for micro drip irrigation systems, small greenhouse ventilation fans. Single/three-phase compatibility works with scattered farm power supplies.
Frequently Asked Questions
Q: We're in North America with a 120V single-phase local grid. Can this 200V single-phase inverter work directly?
A: No, this model only accepts 200-240V single-phase power. You'll need a step-up transformer or consider a 120V-compatible inverter model.
Q: We connected it to a small fan but it trips "OL" (overload) immediately on startup. What's wrong?
A: Extend the acceleration time and switch to VT (light-load) mode. Fans have high startup torque that requires proper configuration.
Q: The speed fluctuates when adjusting the analog knob—how to stabilize it?
A: Use shielded cable for 0-10V control wires and increase the analog filter time to smooth out signal jitter.
Q: Can we directly connect this inverter to a PM motor?
A: Yes, but you must adjust settings to enable PM motor control and perform auto-tuning for optimal performance.
Q: The display shows "STO"—what does this mean?
A: "STO" indicates Safe Torque Off is active. The safety input terminals need to be properly connected to unlock the inverter.
