Installation gap: Single driver up and down ≥ 100mm, left and right ≥ 30mm; for parallel installation, L8-35=1 should be set, and for horizontal installation, some models require an external cooling fan (such as B001-B012, which requires a 0.18m ³/min air flow fan)

Disassembly and assembly operation: The front cover/keyboard requires a specified size screwdriver (blade width ≤ 2.5mm) to avoid touching the internal capacitors (after power failure, wait for voltage ≤ 50Vdc)

2. Electrical installation specifications

Main circuit wiring:

Terminal functions: R/L1/S/L2/T/L3 (input), U/T1/V/T2/W/T3 (motor output), B1/B2 (braking resistor), grounding terminal (200V class ≤ 100 Ω, 400V class ≤ 10 Ω)

Wire specifications: Recommended 2.5mm ² for 200V single-phase B001 model, 25mm ² for 400V three-phase 4060 model, tightening torque 0.5-5.5N · m (depending on terminal size)

Control circuit wiring:

Signal mode: MFDI supports Sink/Source mode, switched through SC-SP/SC-SN jumper

Wiring requirements: Shielded twisted pair, length ≤ 50m, distance from main circuit ≥ 30cm, to avoid electromagnetic interference

Startup and Debugging Process

1. Operation preparation

Parameter settings:

General setting mode (SrUP): including 26 core parameters such as control mode (A1-02), acceleration and deceleration time (C1-01/C1-02), motor parameters (E2-01~E2-04), etc

Application preset (A1-06): Automatically optimize parameters for specific scenarios, requiring initialization (A1-03=2220/3330)

Keyboard operation: Supports LOCAL/EMOTE switching, RUN/STOP keys (STOP key priority can be disabled through o2-02), can backup/restore parameters (o3-01)

2. Auto Tuning

Tuning type:

Applicable scenarios for motor type tuning method parameter settings

Induction motor rotation tuning T1-01=0. The motor can disconnect from the load and requires a no-load rate of ≥ 30%

Induction motor static tuning T1-01=1 motor cannot rotate, load ≤ 30%

PM motor rotation tuning T2-01=4 needs to disconnect the load and automatically detect motor parameters

PM motor static tuning T2-01=1 motor fixed, suitable for non rotating scenarios

Prerequisite: Enter the motor nameplate parameters (rated power, voltage, current, number of poles), disable safe disable input during tuning, and avoid personnel approaching rotating parts.

3. Test Run

No load test: Start at a frequency of 6Hz, gradually increase to the rated frequency, and check the motor direction, vibration, and current (≤ rated current)

Load testing: Verify acceleration/deceleration response and torque output, fine tune parameters through C4-01 (torque compensation) and n1-02 (anti oscillation gain)

Checklist: Confirm power supply voltage, wiring correctness, protection parameters (L1-01 motor overload protection), and control signal effectiveness

Standard Compliance and Safety

1. Main compliance standards

EU CE: Complies with LVD (2014/35/EU), EMC (2014/30/EU), Machinery Directive (2006/42/EC), requires the use of built-in EMC filters (model suffix E) and proper grounding

UL in the United States and Canada: Compliant with UL 61800-5-1, branch circuit protection requires designated fuses (such as FWH-25A14F for B001), and control circuits require UL certified Class 2 power supply

China RoHS: Restricting harmful substances such as lead and mercury, providing a list of hazardous substances

2. Core safety requirements

Electrical safety: Wait for at least 5 minutes after power failure, prohibit live wiring/cover removal, grounding wire cross-section ≥ 10mm ² (copper core)

Mechanical safety: It is prohibited to grip the keyboard/front cover during lifting, the installation area should be free of flammable materials, and the emergency stop circuit should be independent of the frequency converter

Functional safety: Safe Disable input (H1/H2/HC) requires Source mode, with a wiring length of ≤ 30m

Operation and maintenance

1. Network communication

Supporting protocol: MEMOBU/Modbus (RS-485), with a maximum baud rate of 115.2kbps, supports master-slave configuration, and can communicate with PLC

Communication settings: The terminal resistor is enabled through DIP switch S2, and the last slave needs to be set to ON. The message format includes address, function code, and data segment

2. Troubleshooting

Common faults: OV (overvoltage), oL1 (motor overload), STPo (motor out of step), oC (overcurrent)

Troubleshooting process: After the fault occurs, power off for cooling, check the wiring → parameter settings → load status → motor insulation, and monitor the operating data (output frequency/current/voltage) through U1 xx

3. Maintenance and disposal

Regular inspection: daily (operation status, abnormal noise), regular (cooling fan replacement, 2-5 years according to model), storage (-20~70 ℃, moisture-proof)

Scrap requirements: Follow the WEEE directive, classify and dispose of electronic components and metal casings, and prohibit the indiscriminate disposal of oil/hazardous substance containing components
