For the first run of a Hope65 Series Smart AC Drive / VFD, confirm the drive model and supply voltage, connect the input supply to the correct input terminals, connect the motor to U/V/W, and make sure the drive and motor are properly grounded.
For safe initial testing, use keypad command mode, digital frequency setting, a low test frequency such as 5 Hz to 10 Hz, then press RUN and check motor rotation, current, vibration, and fault status.
Stop commissioning and contact technical support if there is visible damage, repeated fault after reset, suspected output short circuit, incorrect voltage class, unsafe wiring, or uncertainty about electrical checks.
Only trained and qualified electrical personnel should install, wire, commission, inspect, or troubleshoot the AC drive / VFD.
Before touching terminals, wiring, braking resistor connections, motor cables, or internal components, switch off all input power, wait at least 10 minutes, and confirm that the DC bus voltage has discharged to a safe level. Do not perform wiring, inspection, or component replacement while power is ON.
The Hope65 Series Smart AC Drive is used to control the speed and operation of three-phase AC motors in industrial applications such as manufacturing lines, pumps, fans, blowers, conveyors, mixers, and general machinery. It supports V/F control, sensorless vector control, integrated G/P mode, keypad operation, terminal operation, analog frequency reference, RS485 communication with Modbus RTU, automatic torque boost, built-in dynamic braking unit, and output frequency control up to 500 Hz where supported by the motor and machine.
This article is written as a practical commissioning workflow. It helps you verify the AC drive model, confirm correct wiring, set basic parameters, run the motor at a low test frequency, verify rotation direction, and identify common setup errors before releasing the machine for production operation.

| Input Type | Terminals | Technical Check |
|---|---|---|
| Single-phase input | L1 / L2 | Use only for compatible 220 V class models. Confirm model before energizing. |
| Three-phase input | R / S / T | Use only for compatible 380 V class models. Check line voltage and phase balance. |
| Protective earth | PE / ground symbol | Drive and motor must be connected to reliable protective earth. |
Connect the three-phase motor output cable to U / V / W. These terminals carry PWM drive output and must go only to the motor. Do not connect capacitors, power-factor correction units, or incoming mains supply to the drive output.
The Hope65 Series includes a built-in dynamic braking unit. A braking resistor may be required when the machine has high inertia, frequent stop/start cycles, fast stopping requirement, or overvoltage faults during deceleration. Connect the braking resistor only to the designated braking resistor terminals according to the exact model wiring diagram.
An AC drive is a power-electronic device. Panel temperature, ventilation, dust, moisture, cable routing, grounding, and altitude directly affect reliability. The Hope65 has IP20 protection and force-air cooling, so it should be installed inside a suitable electrical panel or protected enclosure.
| Check Point | Requirement | Why It Matters |
|---|---|---|
| Mounting direction | Vertical mounting | Supports natural and forced airflow through the heat path. |
| Operating temperature | -10°C to +50°C, with derating where required | High temperature causes overheating trips and reduced component life. |
| Humidity | 20% to 90% RH, no condensation | Condensation can damage PCB and power modules. |
| Cable routing | Separate power, motor, analog, and communication cables | Prevents unstable analog reference and RS485 communication issues. |
| Altitude | Below 1000 m without derating; derate above 1000 m | Air density reduces at altitude, lowering cooling effectiveness. |
Before switching ON the AC drive, complete this checklist. Do not skip these checks even if the panel wiring appears simple.
| No. | Check | Pass Condition |
|---|---|---|
| 1 | Drive model and supply voltage | Supply voltage matches the exact drive voltage class. |
| 2 | Input wiring | Supply is connected only to L1/L2 or R/S/T as applicable. |
| 3 | Motor wiring | Motor is connected only to U/V/W. |
| 4 | Grounding | Drive and motor are properly earthed. |
| 5 | Mechanical load | Motor shaft and machine are free to rotate, or load is safely isolated for first test. |
| 6 | Cooling path | Drive ventilation path is not blocked and panel airflow is available. |
| 7 | Loose objects | No screw, wire strand, cable piece, or conductive object is inside the panel or drive area. |
For the first test, use the keypad as the command source and digital setting as the speed source. This avoids confusion from external pushbuttons, PLC commands, analog wiring, or Modbus settings during initial commissioning.
F0-21 Command Source Select keypad, terminal, or communication run command. | F0-02 Frequency Source Select digital, analog, pulse, PID, multi-speed, or communication speed reference. | F0-01 Preset Frequency Use 5–10 Hz for the first motor rotation test. |
F0-13 / F0-14 Ramp Time Increase acceleration/deceleration time for heavy or high-inertia loads. | F3 Group Motor Data Enter rated power, voltage, current, frequency, and speed from motor nameplate. | First-Test Rule Keypad command + digital frequency + 5–10 Hz + safe ramp time + verified motor data. |
| Function | Parameter | First-Test Setting | Technical Purpose |
|---|---|---|---|
| Control method | F0-00 | V/F for simple first test; vector control after motor data setup if required | Selects the motor-control algorithm. Vector control needs accurate motor parameters. |
| Preset frequency | F0-01 | 5.00 Hz to 10.00 Hz | Reduces mechanical risk during first rotation check. |
| Frequency source | F0-02 | Digital setting | Ensures the speed reference is controlled from the keypad setting, not from missing analog/communication input. |
| Command source | F0-21 | Operation panel / keypad command | Allows RUN and STOP from keypad during commissioning. |
| Maximum frequency | F0-09 | Set according to motor/application requirement | Prevents accidental operation above machine or motor limit. |
| Acceleration time | F0-13 | Increase for heavy load | A very short acceleration time can cause overcurrent trips. |
| Deceleration time | F0-14 | Increase for high-inertia load | A very short deceleration time can cause DC bus overvoltage. |
Motor nameplate data must be entered correctly when the application requires better torque response, vector control, motor protection accuracy, or stable low-speed operation. Incorrect motor current, voltage, frequency, or speed values can cause weak torque, overload trips, failed tuning, or unstable running.
| Parameter | Description | Commissioning Note |
|---|---|---|
| F3-00 | Motor rated power | Enter from motor nameplate. Do not guess from machine size. |
| F3-01 | Motor rated voltage | Match motor connection and supply class. |
| F3-02 | Motor rated current | Critical for overload protection and vector control behavior. |
| F3-03 | Motor rated frequency | Usually 50 Hz or 60 Hz depending on motor and region. |
| F3-04 | Motor rated speed | Required for accurate control and speed estimation. |
After wiring and parameter checks are complete, perform the first test using keypad operation. Keep the first test short and controlled.
After the motor runs correctly from the keypad, configure the required final control method. Do not troubleshoot terminal, analog, or Modbus operation until keypad operation has been verified.
| Control Requirement | Setup Direction | Main Checks |
|---|---|---|
| Keypad start/stop and keypad speed | Use keypad command and digital frequency setting. | Check F0-21, F0-02, F0-01, RUN/STOP operation. |
| External pushbutton or selector switch | Use terminal command source and assigned digital input functions. | Check DI wiring, source/sink selection, active level, and terminal command mode. |
| Potentiometer speed control | Use analog input or built-in potentiometer frequency source. | Check AI jumper, 10V/GND wiring, shielded cable, and AI curve settings. |
| PLC analog speed control | Use AI1 with correct voltage/current jumper and parameter setup. | Confirm 0–10 V or 4–20 mA signal type, scaling, and common reference. |
| RS485 / Modbus control | Use communication command and/or communication frequency reference. | Check RS485 A/B polarity, slave address, baud rate, parity, and Modbus master settings. |
