Installation Guide (Mechanical+Electrical)

1. Mechanical installation specifications

(1) Environmental requirements

Temperature: IP20/UL Open Type is -10 ° C~+50 ° C, IP20/UL Type 1 is -10 ° C~+40 ° C, freezing is prohibited;

Humidity: ≤ 95% RH and no condensation, to avoid internal short circuits caused by condensation;

Altitude: Maximum 1000m, with a 1% reduction in output current for every 100m increase in the 1000-4000m range;

Environmental cleanliness: Pollution level 2 (IEC 60664-1), free of impurities such as oil mist, dust, corrosive gases, metal powders, etc.

(2) Installation operation

Installation method: Supports vertical, horizontal, and rotary installation. For small models (such as B001-B012) installed horizontally, an external cooling fan is required;

Installation gap: Reserve ≥ 100mm vertically and ≥ 30mm horizontally for a single frequency converter. When installing side by side, set parameter L8-35=1 and align the top of the drive for easy fan replacement;

Disassembly and assembly of components: The front cover needs to be unlocked with a straight screwdriver with a blade width of ≤ 2.5mm and a thickness of ≤ 0.4mm. The keyboard can be disassembled by pressing the right buckle. Remote installation requires a dedicated extension cable (up to 3m in length).

(3) Heat dissipation and protection

Heat dissipation requirements: The driver needs to be cooled naturally or by an external fan, and when installed horizontally, the airflow direction should be ensured to be unobstructed;

Temporary protection: During installation, a temporary cover plate is needed to cover the driver to prevent foreign objects such as metal shavings and wire heads from entering the interior.

2. Electrical installation specifications

(1) Main circuit wiring

Terminal function:

Input terminals: L/L1, N/L2 for single-phase use; Three phase use R/L1, S/L2, T/L3;

Output terminals: U/T1, V/T2, W/T3 (connected to motor);

Auxiliary terminals:+1,+2 (connected to DC reactor, default jumper needs to be removed), B1, B2 (connected to braking resistor);

Grounding terminal: For 200V class, the grounding resistance should be ≤ 100 Ω, for 400V class, it should be ≤ 10 Ω, and the minimum cross-sectional area of the protective grounding wire should be 10mm ² (copper core).

Wire selection:

Material: UL certified copper core wire, temperature resistance of 75 ℃, voltage resistance of 600V;

Specification: Choose 0.75-25mm ² according to different models, such as 2.5mm ² for B001 and 25mm ² for 4060;

Tightening torque: 0.5-0.6N · m for M3 screws, 1.5-1.7N · m for M4 screws, and 5-5.5N · m for M6 screws to avoid overheating or damage to terminals due to excessive looseness.

(2) Control circuit wiring

Signal mode:

Input mode: MFDI supports Sink/Source modes, which can be switched between SC-SP (Sink mode) or SC-SN (Source mode) jumper. It is prohibited to close both SC-SP and SC-SN simultaneously;

Input signal: Digital input (S1-S7) supports forward rotation, reverse rotation, fault reset and other functions, while analog input (A1/A2) supports 0-10V voltage signal or 4-20mA current signal (A2 terminal is switched through DIP switch);

Output signal: Digital output (MA/MB/MC) is relay output, analog output (AM) supports 0-10V/4-20mA signal, pulse output (MP) maximum 32kHz.
