Integration & Application FAQs

Which Yaskawa servo motors are compatible with this drive?

The Yaskawa SGD7S-2R8A00A is designed for Sigma-7 series motors up to 0.4 kW, such as the SGM7J-04AFC6S. Ensure the motor's rated current is within the drive's 2.8A continuous rating for optimal matching.

What does the “2R8A00A” suffix in the model number indicate?

This suffix defines key specs: '2R8' denotes the continuous output current (2.8A), and 'A00A' specifies the voltage class (200V), basic functionality, and standard communication interface (pulse train).

Do I always need an external brake resistor with this drive?

Yes, for most applications. The drive has limited internal capacity to absorb regenerative energy from the motor during deceleration. An external resistor meeting the 40 Ω minimum requirement is necessary to prevent overvoltage faults.

Can I use this drive for simple speed control without a complex controller?

Yes. You can set the drive to "Speed Control Mode" and provide a simple analog voltage signal (0 to ±10V) to command motor speed. This allows operation directly from a PLC analog output or a potentiometer.

What is a common commissioning mistake with Sigma-7 drives?

Skipping the auto-tuning procedure. After connecting the motor, you must perform a rotational or stationary auto-tuning. This allows the drive to identify the motor's electrical characteristics and optimize its control loops for stable, responsive motion.
