Frequently Asked Questions about SC726A-001-PM2009:
Q: How does the 320 VDC internal bus voltage benefit the SC726A-001-PM2009 system?
A: The internal 320 VDC regulation enhances energy conversion consistency. This ensures reduced voltage ripple and improved motor response stability.
Q: Why is a 3-phase 240 Vac input preferred in the SC726A-001-PM2009 controller?
A: The 3-phase input reduces electrical losses and improves efficiency under continuous industrial loads. It also supports smoother torque generation during demanding cycles.
Q: Why is a 40 kW peak shunt regulator integrated in the SC726A-001-PM2009 model?
A: The peak shunt regulator absorbs excess dynamic energy during braking or sudden load drops. It protects connected drives from voltage overshoot and damage.
Q: How does the SC726A-001-PM2009 optimize performance at 3000 rpm?
A: The operating speed of 3000 rpm balances torque and velocity. It ensures responsive behavior in fast-cycle manufacturing tasks.
Q: What mechanical advantage is gained from the 28.8 Nm continuous stall torque?
A: The high stall torque maintains force without movement, essential in holding or press-fit applications. This keeps mechanical loads firmly controlled under stress.
