1.4 Section 3:  Series Servos (Digital Mode)
The Digital

Series Servo features include:
•
World-leading reliability
•
Low maintenance, no component drift, no commutator brushes
•
All parameters digitally set; no re-tuning required
•
Absolute encoder eliminates re-homing (requires optional battery kit)
•
An optional motor brake is available
•
Optional IP67 environmental rating is also available for most motors
•
High resolution 64K count per revolution encoder feedback (incremental or
absolute)
The Servo motors, proven on over three million axes installed worldwide, offer the highest
reliability and performance. The latest technologies such as high-speed serial encoders and
high efficiency Integrated Power Modules (IPMs), further enhance customer benefits.
The servo system is unique in that all the control loops - current, velocity and position - are
closed in the motion controller. This approach reduces setup time and delivers significant
throughput advantages even in the most challenging applications.
The servo drives are less costly to integrate and maintain. Control circuits are unaffected by
temperature changes. There are no personality modules. The servos have a broad
application range, that is, a wide load inertia range, flexible acc/dec and position feedback
configurations, etc.
Extensive customization features are available to optimize performance and overcome
machine limitations. IPM based servo amplifiers require 60% less panel space than
conventionally switched amplifiers and produce 30% less heat.
