Frequently Asked Questions
How does this servo motor ensure load stability in vertical axes or during unexpected power interruptions?
The motor includes a 6.5 Nm holding brake for reliable mechanical locking. It maintains position under load when power is disengaged.
Is this servo motor suitable for heavy-duty automation systems with continuous torque demand?
It delivers 9.2 Nm continuous torque, enabling stable drive output in sustained high-load operations. This supports conveyors, press systems, and rugged actuators.
What drive tuning behavior can be expected when optimizing force output in closed-loop control?
It features a 0.875 Nm/A torque constant, providing predictable torque per amp of input. This simplifies precise gain tuning in motion control loops.
Can this servo motor withstand high short-term load surges without tripping or overheating?
Its 54 A peak current capacity handles torque bursts during acceleration or impact. This allows reliable performance under dynamic or shock-loaded conditions.
How does the rotor inertia affect responsiveness in axes with rapid speed transitions?
It has 22×10⁻⁴ kg·m² rotor inertia, balancing torque stability with speed agility. This improves control in systems requiring fast directional shifts.
