Ultra3000i Indexing Digital Servo Drives
In addition to the standard Ultra3000 features, the Ultra3000i indexing drive features:
• 64 configurable index profiles for absolute, incremental, registration-type positioning (stored in
non-volatile memory), and jog.
• Menu-driven parameter entry allowing up to 64 stored motion profiles, selectable via I/O or linked via
software sequencing.
• Ability to blend indexes without coming to a complete stop.
• Built-in homing routines.
• Ability to stop an index via digital inputs or serial inputs.
• Jog motion profiles.
• Eight preset positions for simple replacement of pneumatic cylinders.
The Ultra3000i indexing drive can execute up to 64 different trapezoidal position moves initiated by digital
I/O and the sequencing of unlimited indexes through the use of the host command language. The benefit
of indexing is that it allows the drive to be cost-effective, high performing and flexible in applications
where past electronic motion control systems were not. The Ultra3000i simplifies and helps reduce costs
by eliminating the need for the command source typically provided by motion controllers, stepper
controllers and PLC servo and stepper cards.
The Ultra3000i indexing drive supports the following four types of index moves:
• Incremental - distance move executed relative to current position
• Registration - distance move executed relative to the registration sensor digital input
• Absolute - position move executed in reference to the home position
• Jog - input level-sensitive move executed while input remains high or maximum distance defined is
achieved
