EV200-0007G-S2: Compact 1HP Single Phase VFD | 0.75kW, 220V
Why Choose This 0.75 kW (1HP) 220V Single Phase VFD?
The EV200-0007G-S2 is the definitive solution for users needing to drive 1HP three-phase motors from a standard household outlet while minimizing installation footprint.
Ideal for 1HP Machine Upgrades:Â This model is perfectly sized for converting fixed-speed 1HP machinery (like drill presses or band saws) to variable speed, offering better control and energy efficiency.
Ultra-Compact Footprint: The narrow body design means you can fit this drive into existing, cramped electrical boxes where traditional, bulkier 1HP drives simply won’t fit.
Reliable in Dusty Environments: Unlike open-chassis drives, the independent air duct helps protect the internal circuit boards from conductive dust found in ceramics or grinding applications.
Cost-Effective Performance:Â It strips away unnecessary features like a built-in braking unit (not required for this power range)Â Â to focus on delivering high-performance vector control at a competitive price point.

Frequently Asked Questions (FAQ)
Can I use this VFD to run a 1HP single-phase motor?
No, absolutely not. The EV200-0007G-S2 is designed to convert a single-phase 220V input into a three-phase 220V output. Connecting a single-phase motor (which has start capacitors) to the output terminals (U, V, W) will damage both the motor and the VFD. You must use a three-phase asynchronous motor.
Does the EV200-0007G-S2 require an external braking resistor?
This specific model (0.75kW) does not have a built-in braking unit, so you cannot directly connect a braking resistor to it. For applications requiring fast stopping, you can use the DC braking function parameters (P6-10 to P6-14) to stop the motor electronically.
What is the recommended input circuit breaker size?
The rated input current for this model is 8.2A. We recommend using a molded case circuit breaker (MCCB) or a fuse rated slightly higher than this, typically around 15A or 20A, to handle the input current without nuisance tripping.
Is the cooling fan always on?
By default, the fan may run continuously, but the EV200 series typically allows for intelligent fan control settings (refer to parameter P8-48) to run the fan only when the unit is running or hot, prolonging fan life and reducing noise in quiet workshop environments.
Quick Start Guide (How-To)
Warning: The following steps are a basic guide. All electrical work must be performed by qualified personnel. Ensure power is off before wiring.
Step 1: Installation
Mount the EV200-0007G-S2 securely on a non-flammable vertical surface. The compact 73mm width allows it to fit into small enclosures or between other devices. Use the 60x129mm mounting hole pattern.
Step 2: Main Circuit Wiring
Connect your Single-Phase 220V supply lines to terminals L1 and L2 (or R/T).
Connect the three wires of your 0.75kW (1HP) three-phase motor to terminals U, V, and W.
Step 3: Control Circuit Wiring
For a simple external run switch, connect a toggle switch between S1 and COM.
For speed control, wire a 1kΩ – 10kΩ potentiometer to the analogue input terminals (+10V, AI, GND).
Step 4: Parameter Setup
Power on the VFD. Navigate to Group P1 and input your motor’s nameplate data (0.75kW, Voltage, Current, Frequency, RPM).
Set P0-02 to “1” to enable the external terminal start switch.
Set P0-03 to “2” (or appropriate value) to enable the potentiometer for speed control.
Step 5: Test Run
Flip the S1 switch. The motor should start smoothly. If it spins backwards, power down and swap any two motor output wires (e.g., U and V).
Core Features & Advantages
High Power Density: Delivers 0.75kW (1HP) of reliable vector control power in a chassis that is only 73mm wide, allowing for maximum performance in minimal cabinet space.
Side-by-Side Mounting:Â Specifically designed for zero-clearance side-by-side installation, enabling high-density configuration for multi-axis machines like textile winders or printing lines.
Superior Low-Speed Torque: Capable of producing 150% starting torque at 0.5Hz, ensuring powerful and smooth startups for high-inertia loads like pottery wheels or flywheel-driven machinery.
Independent Air Duct Design:Â Features a straight up-and-down independent cooling channel that separates airflow from electronic components, significantly improving dust resistance in environments like ceramic studios or woodshops.
