Frequently Asked Questions
Can I use the single-phase model (2R2G-S2) with my three-phase 2.2kW motor?
Yes. The 2R2G-S2 accepts single-phase 230V input and provides three-phase 230V output to power standard three-phase motors—ideal for workshops without 3-phase grid access. The inverter generates the missing phases electronically. Note: Current draw is higher (23A vs. 11A)—ensure your supply circuit can handle the load. Full 2.2kW output is available.
Do I need an external brake resistor with the built-in brake unit?
The brake chopper is built-in, but the braking resistor is external. You only need to connect an external braking resistor if your application requires rapid deceleration or handles high-inertia loads. For most pump, fan, and general automation applications with gradual deceleration, the resistor is optional. This integrated design saves approximately $50-100 in external component costs.
How does sensorless vector control improve my CNC application?
Sensorless vector control provides ±0.5% speed accuracy and 150% starting torque at 0.5Hz—critical for CNC spindle orientation. Unlike standard V/Hz control, it maintains constant speed during cutting operations for better surface finish and longer tool life. No encoder wiring is needed, reducing system complexity versus traditional closed-loop systems.
Can I integrate this VFD with my existing PLC using Modbus?
Yes. The RS485 port supports Modbus RTU protocol with slave address configuration and baud rates up to 115200 bps. You can remotely control start/stop, frequency, and direction; monitor output current and fault status. For non-Modbus systems, analog inputs (0-10V, 4-20mA) and digital I/O are available for hardwired control.
What protection features prevent motor damage?
The 100PV provides comprehensive protection: over-current (150% for 60s), over-voltage, under-voltage, motor overload, and inverter over-temperature. The auto-tuning function measures motor resistance and inductance to optimize current control. Additional features include stall prevention and automatic torque boost for heavy starts—significantly extending motor lifespan.
