Safety regulations

2.1 Warning System

The manual divides safety warnings into two levels, clarifying the consequences of risks and operational requirements:

Typical scenario examples of warning type meanings

Warning: Incorrect operation may result in death or serious injury. Disassembling the front cover while live, connecting input power to output terminals, and operating without grounding

Incorrect handling of the solution may result in minor injuries or property damage. Touching the heat sink, using incompatible chemicals, and installing in a vibrating environment

2.2 Mandatory Safety Requirements

Grounding: D-type grounding (formerly Class 3 grounding) must be used, and the grounding wire diameter should be ≥ 3.5mm ² (refer to the terminal specification table for details) to ensure safe conduction of leakage current in case of fault.

Power off waiting: After disconnecting the input power, wait for at least 15 minutes to confirm that the charge light is off and the DC main circuit voltage is ≤ 45V before touching the terminal.

Installation base: It needs to be fixed on a metal base that can withstand the weight of the equipment to prevent it from falling; Choose NEMA 3R protection model (such as 5000 series) for outdoor/harsh environments.

Emergency stop: It must be equipped with an emergency stop device independent of the frequency converter (such as mechanical braking), and the frequency converter alone cannot achieve immediate shutdown.

Modify parameters: Press the ENT key to enter editing, and then use the △/▽ keys to adjust the values;

Save parameters: Press the ENT key again, and the parameters and values will alternate to indicate successful saving;

Reset default: Set the basic parameter "Eyp" to 3 to restore all parameters to their factory default values (with the need to shut down first).

Installation and wiring

4.1 Installation environment requirements

Temperature: Operating environment temperature * * -10 ℃ -50 ℃ * *. When the ambient temperature is greater than 40 ℃, the warning label on the top of the equipment should be removed and the rated output current should be reduced (such as the current of the 2007P model dropping from 4A to 3.6A at 40-50 ℃);

Humidity: Relative humidity of 20% -93%, no condensation;

Vibration: Vibration acceleration<5.9m/s ² (10-55Hz), avoid installing near strong vibration equipment such as machine tools;

Other: No dust, corrosive gases, oil mist, keep away from heat sources (such as transformers, heaters).

4.2 Terminal Wiring Specification

Main circuit terminals:

Screw specifications: M3 (low power)/M3.5 (high power), tightening torque of 0.8N · m/1.0N · m respectively;

Wiring requirements: Connect the input (R/L1, S/L2, T/L3) to the power supply, and the output (U/T1, V/T2, W/T3) to the motor. Reverse connection is prohibited as it may damage the inverter;

Grounding terminal: It needs to be independently grounded with a wire diameter of ≥ 3.5mm ² (refer to section 10.1 wiring table).

Control circuit terminals:

Screw specifications: M2/M3, wire diameter 0.3-1.5mm ², sheath stripping length 5-6mm;

Wiring taboos: Control circuit and main circuit wiring should be separated (not parallel, not bundled, different conduit) to avoid interference.

4.3 Wiring precautions

It is prohibited to connect capacitive devices (such as noise filters and surge absorbers) on the output side, as this may cause a fire;

The length of the main circuit line is ≤ 30m, and if it exceeds this limit, the wire diameter needs to be increased (for example, for a 200V level 0.75kW motor, a wire length>30m requires a wire of ≥ 2.5mm ²);

When multiple inverters share a power supply, each one needs to be equipped with an independent MCCB (circuit breaker) to avoid the spread of faults.

Operation and monitoring

5.1 Operating Mode

Panel control: Set CMod=1, start with RUN key, stop with STOP key, adjust frequency with △/▽ key;

Terminal control: Set CMod to 0 and control operation by short circuiting the F-CC (forward rotation) and R-CC (reverse rotation) terminals;

Jog operation (JOG): Set the input terminal function to "JOG", the motor runs at a fixed frequency of 5Hz when short circuited, and stops freely after disconnection;

Preset speed operation: By allocating SS1-SS4 terminals (a total of 4 terminals), 15 levels of preset speed can be achieved (F287-F294 parameters need to be set).

5.2 Status Monitoring

Monitoring content: The output frequency, load current (%/A), input voltage (DC), output voltage (%/V), cumulative running time (0.01=1 hour), etc. can be viewed through the "status monitoring mode" (press MON button twice);

Fault display: When tripped, the LED displays a fault code (such as "OC1" indicating acceleration overcurrent), and the FL relay operates (fault output);

Alarm message: Non trip warning (such as "rEr" indicating retry), only prompts not to stop the machine, and attention should be paid to the equipment status.

Fault handling

6.1 Common tripping faults and remedies

Fault code, fault type, possible cause, remedial measures

OC1 acceleration overcurrent acceleration time is too short, motor impedance is too small, extending ACC time (such as changing from 10s to 20s), checking motor insulation

OP2 deceleration overvoltage deceleration time too short, excessive regenerative energy prolongs dEC time, F305 is enabled (overvoltage limited operation)

OH inverter overheating fan fault, poor ventilation, environment overheating. Replace the fan, clean the ventilation opening, and improve environmental heat dissipation

OL2 motor overload, excessive load, long low-speed operation time to reduce load, adjust electronic thermal protection level (OLn=4 compatible with VF motor)

6.2 Fault reset method

Panel reset: In the shutdown state, press the STOP button to display "LLr", then press the STOP button to reset (the fault needs to be eliminated first);

External reset: Short circuit the control terminal RST to CC and disconnect it (RST function needs to be assigned first);

Power off reset: Disconnect the input power supply, wait for 15 minutes, and then power it back on (used in emergency situations, not recommended for frequent operation).

Maintenance and Quality Assurance

7.1 Regular Maintenance Plan

Maintenance Type Cycle Maintenance Content Precautions

Daily inspection of environmental temperature, vibration and noise, load current, and alarm light status without stopping the machine. Visual and instrument checks are required

During the 3-6 month maintenance cycle, terminal tightening, dust removal (ventilation/circuit board), and capacitor inspection must be carried out by cutting off the power for 15 minutes and confirming that the voltage is ≤ 45V before operation

Long term storage: Power on for more than 5 hours every 2 years (motor disconnected), gradually increase the voltage with a transformer to restore capacitor performance, and avoid direct commercial power supply

7.2 Service life and replacement of vulnerable parts

Cooling fan: With a lifespan of approximately 30000 hours (2-3 years of continuous operation), it should be replaced in case of abnormal noise or stoppage;

Electrolytic capacitor: The lifespan of the smoothing capacitor in the main circuit is about 5 years (normal environment). Check for no leakage and ensure that the safety valve is not protruding. Otherwise, replace it;

Fuse: with a lifespan of about 10 years, regularly inspect the appearance, and replace it with the same specification (such as CC/J grade 8A) after melting.

7.3 Warranty Scope

Warranty period: 12 months from the delivery date, only covering the frequency converter host;

Free repair: Parts malfunctions that occur under normal use (such as fans and capacitors);

Disclaimer:

Improper use (such as overload, misconnected power supply);

Self modification/repair;

Natural disasters (fire, earthquake) or abnormal voltage;

Out of range applications (such as driving single-phase motors).

Compliance and Disposal

8.1 Certification Compliance Requirements

CE certification:

EMI filters need to be installed on the input side (such as EMFA2006Z suitable for 200V low power);

Shielded wires are used for the main circuit/control circuit, and the shielding layer is grounded (with a distance of less than 10cm from the inverter);

UL/CSA certification:

Use copper wires above 75 ℃, equipped with CC/J level fuses (such as 4A fuses for the 2002P model);

Branch circuit protection must comply with local electrical regulations (such as NEC in the United States and CEC in Canada).

8.2 Equipment disposal

Mandatory requirement: Waste frequency converters must be disposed of by professional industrial waste disposal institutions (self disassembly is prohibited);
