2.3 Selecting Other System Components
Selecting an
indexer
The 6430 drive requires STEP and DIRECTION inputs.
Select an indexer that provides, as a minimum, these
commands. A compatible indexer will provide the capability to
drive the input circuits shown in Section 2.5.4. For most
applications that operate at speeds above 300 RPM, an indexer
that can ramp the step frequency is required.
Selecting a
motor
The 6430 is designed for use with Pacific Scientific’s line of
hybrid stepper motors or most other 2 phase stepper motors.
The drive works with either the standard line or the enhanced
high performance line of stepper motors. The motor winding
current rating must be compatible with the output current of
the drive package.
Refer to the Torque/Speed Curves in the Pacific Scientific
“Motion Control Solutions Catalog” or contact your local
Pacific Scientific distributor for sizing and motor compatibility
assistance.
