Frequently Asked Questions
Do I need an external braking resistor with the built-in brake unit?
The brake chopper is built-in, but the braking resistor is external. The 100PV 4kW models (004G-2, 004G-4) include an internal IGBT brake chopper circuit that manages regenerative energy during deceleration. You must connect an appropriately sized external braking resistor (typically 80-150Ω, 1-2kW rating for 4kW drives) to dissipate this energy as heat. For standard pump and fan applications with gradual deceleration ramps, the resistor may be optional. For CNC spindles, hoists, or high-inertia loads requiring rapid stops, the resistor is essential. Contact our technical team for sizing calculations based on your duty cycle.
Should I choose the 230V (-2) or 400V (-4) model for my 4kW motor?
Select based on your facility’s nominal voltage. The 004G-2 (230V) model accepts three-phase 200-240V input, common in North American industrial settings (where 208V or 240V three-phase is available) and some Asian regions. It delivers 16A output current. The 004G-4 (400V) model accepts three-phase 380-440V input, the European/International industrial standard, delivering 9A output at higher voltage (lower current = less copper loss). Both provide identical motor control performance. Critical: Verify your motor’s voltage rating matches the inverter output—230V motors on 400V inverters will fail immediately. When in doubt, check your motor nameplate or contact our technical support.
Can this 4kW VFD replace my existing star-delta starter for energy savings?
Yes, with significant operational benefits. Replacing a star-delta starter with the 100PV 4kW VFD provides three key advantages: (1) Soft-start capability eliminates mechanical shock, water hammer in pumps, and belt slippage; (2) Variable speed control optimizes flow/pressure via speed rather than inefficient throttling, delivering 30-50% energy savings at partial loads; (3) Built-in braking enables controlled deceleration versus coast-to-stop. For a 4kW motor running 6,000 hours/year at 75% average load with €0.12/kWh electricity, annual savings typically exceed €800—payback in 12-18 months. The RS485 interface also enables remote monitoring impossible with traditional starters.
How do I integrate this VFD with my Siemens/Mitsubishi PLC?
Integration is straightforward via RS485 Modbus RTU. Connect the inverter’s RS485+ and RS485- terminals to your PLC’s communication port. Configure the drive parameters: set the slave address (1-247), baud rate (9600-115200 bps), and parity to match your PLC network. The 100PV supports standard Modbus function codes 03 (Read Holding Registers), 06 (Write Single Register), and 10 (Write Multiple Registers). Key parameters accessible: output frequency (register 0001), output current (0002), DC bus voltage (0003), and fault status (0004). For non-Modbus systems, hardwired control via digital inputs (3-wire/2-wire) and analog input (0-10V or 4-20mA) is always available. We provide sample PLC programs and parameter lists for common brands upon request.
