User Manual Guide for Sanken SAMCO-vm05 Series Inverter

Basic Settings and Function Adjustments for the Inverter

1. Torque Compensation Function and Startup Mode Configuration

The Sanken SAMCO-vm05 series of inverters offers flexible torque compensation and startup mode settings to meet various operational requirements.

Torque Compensation Function

The torque compensation function allows fine-tuning of the inverter’s output to compensate for variations in motor load and maintain stable operation. To set the torque compensation:

• Navigate to the function code menu (Cd004).
• Enter the desired compensation percentage (0-20%). A higher percentage increases the output voltage at low frequencies, enhancing torque output.

Startup Mode Configuration

The startup mode determines how the inverter initiates the motor. To configure the startup mode:

• Navigate to the function code menu (Cd009).
• Select the appropriate startup mode:
  • Cd009 = 1: Start from the set startup frequency.
  • Cd009 = 2: Start with speed tracking (for smooth transitions from motor coasting to active control).
  • Cd009 = 3: Apply DC brake before starting from the set startup frequency (useful for loads that may be rotating unexpectedly).

2. Configuring Frequency Parameters

Proper configuration of frequency parameters is crucial for smooth and efficient motor operation.

Startup Frequency (Cd010)

This sets the initial frequency at which the motor begins to accelerate. To set:

• Navigate to the function code menu (Cd010).
• Enter the desired startup frequency (0.05-20 Hz).

Run Start Frequency (Cd011)

This sets the minimum frequency required to maintain motor operation. To set:

• Navigate to the function code menu (Cd011).
• Enter the desired run start frequency (0-20 Hz). Ensure it is lower than the startup frequency to prevent unintended motor stops.

Lower Limit Frequency (Cd008)

This sets the minimum allowable output frequency. To set:

• Navigate to the function code menu (Cd008).
• Enter the desired lower limit frequency (0.05-200 Hz).

Upper Limit Frequency (Cd007)

This sets the maximum allowable output frequency. To set:

• Navigate to the function code menu (Cd007).
• Enter the desired upper limit frequency (30-600 Hz, depending on the model).

3. Activating DC Brake and Configuring Related Parameters

The DC brake function helps quickly stop the motor by applying a DC current to the motor windings.

Activating DC Brake

To activate the DC brake:

• Ensure the DC brake function is enabled in the function code menu (typically defaulted to enabled).
• Configure the DC brake start frequency (Cd014), brake time (Cd015), and brake strength (Cd016) as required.

Configuring DC Brake Parameters

• DC Brake Start Frequency (Cd014): Sets the motor speed at which the DC brake engages (0.2-20 Hz).
• DC Brake Time (Cd015): Sets the duration of the DC brake application (0.1-10 seconds).
• DC Brake Level (Cd016): Sets the strength of the DC brake (1-10 levels).

By carefully configuring these parameters, you can optimize the performance and reliability of your Sanken SAMCO-vm05 series inverter, ensuring smooth and efficient motor control tailored to your specific application needs.
