2. **Structural Design**

   - **Installation Method**: Supports rail mounting or wall-mounted installation. It is necessary to maintain a vertical installation plane within an inclination range of ±10°.Siemens servo motor 1FL6032-2AF21-1LG1and the SINAMICS V90

   - **Protection Level**: IP20, and it needs to be used in a dry indoor environment.

   - **Dimensions**: 57mm×125mm×165mm (width×height×depth), and the weight is approximately 3.5kg.

 II. Wiring and Installation

1. Main Circuit Wiring

- **Power Input**: Connect L1/L2/L3 to three-phase alternating current (200-480V). Note that the phase sequence does not need to be strictly corresponding.

- **Motor Output**: Connect U/V/W to the motor windings, and ensure that the wiring is firm (recommended wire cross-sectional area: 1.5-2.5mm²).

- **Bypass Contactor**: There is a built-in bypass contactor, and no additional installation is required. The thyristor will be automatically bypassed after the starting is completed.

2. Control Circuit Wiring

- **Control Power Supply**: Connect 24V AC/DC to terminals 1 (+) and 2 (-). Shielded wires need to be used to avoid interference.

- **Start/Stop Signals**:

  - **Passive Contacts**: Connect the start signal (such as a button) to terminals 3 and 4 (default normally closed contacts, start when closed).

  - **Fault Reset**: Terminals 5 and 6 are used for fault reset (default normally closed contacts, reset when closed).

- **Status Feedback**:

  - **Operation Indication**: Terminals 7 and 8 output the operation signal (24V DC).

  - **Fault Indication**: Terminals 9 and 10 output the fault signal (24V DC).

3. Installation Precautions

- **Environmental Requirements**: The operating temperature is from -25°C to +60°C, and the storage temperature is from -40°C to +80°C. Avoid dust and corrosive gases.

- **Wiring Specifications**: The main circuit and the control circuit need to be wired separately, with a distance of ≥10cm to prevent electromagnetic interference.

- **Prohibited Operations**: It is not allowed to connect capacitive components (such as reactive power compensation devices) between the soft starter and the motor.

 III. Parameter Setting and Debugging

1. Basic Parameters

- **Starting Time**: The default is 5 seconds (adjustable range: 0.5-60 seconds), adjusted according to the load characteristics.

- **Stopping Time**: The default is 3 seconds (adjustable range: 0.5-60 seconds), used to control the voltage drop rate during shutdown.

- **Current Limit Value**: The default is 3 times the rated current (adjustable range: 1.5-5 times), to avoid excessive starting current.

2. Advanced Parameters (Need to be set through the operation panel)

- **Overload Protection Threshold**: The default is 1.15 times the rated current (adjustable range: 0.5-1.5 times), and it needs to be calibrated according to the parameters on the motor nameplate.

- **PTC Sensor Configuration**: If an external PTC thermistor is connected, this function needs to be enabled in the parameters and the trigger temperature needs to be set.

- **Undervoltage Protection**: The default is 70% of the rated voltage (adjustable range: 50%-90%), to prevent equipment damage caused by too low voltage.

3. Operation Panel Instructions

- **LED Indicators**:

  - **RUN**: The green light is on during operation.

  - **FAULT**: The red light is on in case of a fault and will go out after reset.

  - **STATUS**: Flashing indicates that the parameters are being set, and a steady light indicates normal standby.

- **Button Functions**:

  - **SET**: Enter the parameter setting menu.

  - **▲/▼**: Select parameters or adjust values.

  - **RESET**: Reset the fault status.

 IV. Fault Diagnosis and Maintenance

1. Common Fault Codes

2. Maintenance Suggestions

- **Regular Inspections**:

  - Check whether the wiring terminals are loose every 6 months and clean the internal dust.

  - Test the conduction voltage drop of the thyristor every year (normally about 1.5V). If it is abnormal, the module needs to be replaced.

- **Replacement of Vulnerable Parts**:

  - **Bypass Contactor**: The service life is about 100,000 times. When starting frequently, the contact wear needs to be checked regularly.

  - **Electrolytic Capacitor**: Replace the filter capacitor of the control circuit every 5 years to prevent voltage fluctuations.

- **Long-term Shutdown**: Disconnect the power supply and power it on for 30 minutes every 3 months to maintain the activity of the electronic components.

V. Typical Application Scenarios

1. **Water Pump Control**: Reduce the water hammer effect through soft starting and extend the service life of the pipeline.

2. **Conveyor Belt Drive**: Smooth starting to avoid goods slipping, and support the synchronous operation of multiple soft starters.

3. **Fan Control**: Reduce the starting current and minimize the impact on the power grid.

VI. Precautions

- **Safe Operation**:

  - Wait for 5 minutes after powering off or use a 200Ω/10W resistor to discharge the DC bus capacitor to avoid electric shock.

  - Disconnect the main power supply and the control power supply during maintenance to ensure that there is no residual voltage.

- **Compatibility Issues**:

  - It does not support the parallel use of the frequency converter and the soft starter, which may lead to harmonic interference.

  - If it is necessary to connect to a PLC, it is recommended to isolate the control signal through an intermediate relay.
