Frequently Asked Questions
What is the primary advantage of torque control mode?
Torque control allows precise force application regardless of speed changes. Therefore, it is ideal for tension control, pressing, and other force-critical processes.
Can this drive operate with three-phase input power?
No, the SGDG-04GT is designed specifically for single-phase input. For three-phase applications, consider other models in the Yaskawa range.
What servo motors are compatible with this amplifier?
It is optimized for Yaskawa Σ-V series motors rated between 100W and 750W. However, it can also work with other brands with proper parameter tuning.
Is external braking resistance required?
Typically, no. The built-in dynamic brake resistor is sufficient for most applications. However, high-duty cycle regeneration may require additional external resistors.
From practical experience, what is crucial during installation?
Proper grounding is essential. Always use the designated ground terminal with a thick, short cable connected directly to the earth ground to minimize electrical noise.
How does natural cooling affect installation spacing?
Since it uses convection cooling, maintain at least 50mm clearance on all sides, especially above and below the unit, for adequate air circulation.
Can this drive be used in a master-follower configuration?
Yes, the SGDG-04GT supports follower operation when synchronized with a master controller via analog or digital torque command input.
