2.2 Selecting a Motor
Selecting a
motor
The 5645 is designed for use with Pacific Scientific’s line of
hybrid stepper motors. The drive works with either the standard
line or the enhanced high performance line of stepper motors.
Use the system Torque/Speed curves for the 5645 shown in the
Pacific Scientific “Motion Control Solutions” Catalog to select
the right motor for your application.
To use a motor not included in the system selections, observe the
following rules:
The motor winding current rating must be equal or greater
than the drive’s output current (5.0, 6.0, 7.5, or 8.0 Amps
RMS depending upon jumper settings).
The electrical and magnetic losses of the motor must not
exceed the motor power dissipation rating. This is of special
concern at high speed and with low inductance motors. The
motor case temperature should not exceed 100 degrees C.
If you need help in selecting a motor, contact your local Pacific
Scientific distributor for sizing and motor compatibility assistance.
2.2.1 Selecting System Components
Introduction
Match your 5645 unit to your other components.
Serial
communications
interfaces
The 5645 requires a serial communication link in order to
develop StepperBASIC software (using PacCom). A serial
interface may be used under software control to interface the
5645 with other user-supplied equipment such as:
Operator displays
Host computers
Programmable controllers (PLC)
The 5645 uses serial communication interfaces supported by the
RS-232 and RS-485 hardware specifications.
