Frequently Asked Questions
What are the installation considerations for the A-Side power connector?
The A-Side placement constrains cabling routing: long runs or tight bends may increase voltage drop and electromagnetic interference, so twisted-shielded power lines and careful layout are essential.
In what cases might one prefer optical Hiperface over digital encoders in closed-loop motion control?
Optical Hiperface offers very low jitter, high accuracy over long cable runs, and built-in multiturn absolute feedback, which improves precision especially in servo loops with fast dynamics.
What is the practical impact of “128 signal periods” on motion resolution?
128 signal periods means the encoder completes 128 full cycles per revolution, giving finer angular discrimination and improved interpolation accuracy for velocity and position control loops.
How does the 120 Nm electrically-released holding brake influence safe operation?
The brake must be energized to release, so loss of power causes immediate locking which is good for safety, but the control system must provide adequate coil current and timing to reliably engage/disengage.
How does winding inductivity (3,200 mH) influence current control bandwidth?
High inductance slows current change (di/dt), reducing achievable bandwidth and making the choice of drive current loop gains and PWM frequency more critical to avoid instability.
