FAQ for 3G3MX2-A4007-V2

What's the difference between ND and HD ratings?
ND (Normal Duty): 150% overload for 60 seconds, for pumps/fans. HD (Heavy Duty): 180% overload for 60 seconds, for conveyors/constant torque. Size HD for high starting torque applications.
Can I run single-phase motor with this VFD?
No, MX2 output is three-phase only. For single-phase motor speed control, use dedicated single-phase VFD or replace motor with three-phase. Input can be single or three-phase depending on model.
Do I need an output reactor?
For motor cable runs under 50m, no reactor needed (built-in EMC filter suffices). For 50-100m runs, add output reactor. Over 100m, use sine-wave filter. Long cables cause voltage reflection that can damage motor insulation.
How do I control speed from PLC?
Three methods: 1) Modbus RTU via RS-485 (most common), 2) Analog input (0-10V or 4-20mA), 3) Digital inputs (multi-step speed). Modbus allows speed control, monitoring, and parameter changes from PLC.
What braking options are available?
Built-in brake chopper accepts external brake resistor for dynamic braking. Calculate resistor value based on deceleration requirements and duty cycle. For holding brake (vertical axis), use motor-mounted electromagnetic brake.
