Description
The PDO5580 is stepper drive packaged in a rugged
steel case painted black with white epoxy silkscreen. Integral
heat sink, mounting brackets, switch covers and
connectors are included with each drive. The drive has
been matched with twelve recommended NEMA 23 and
34 motors in order to create a complete stepper motion
solution.
The PDO5580 provides the user with four modes of operation
to choose from, Self test, Pulse & Direction, Joystick
or Oscillator. The specific operation mode desired
is selected during set up via DIP switch. DIP switchs are
also provided for setting the drive’s step resolution as
well as the motor current.
Self Test Mode is used for troubleshooting. If you are
unsure about the motor or signal connections to the
drive you can use the self-test.
Pulse & Direction Mode allows the PDO5580 to receive
step pulses from an indexer such as the Applied
Motion’s Si-100 or Si-1, or from a PLC or any other external
controller.
Joystick Mode allows speed and direction to be determined
by an external analog voltage. STEP and DIR inputs
can be used for limit switches. SPEED input selects
speed range. LO SPEED and HI SPEED pots adjust the 2
speed ranges.
Oscillator Mode can control speed by onboard potentiometers
and/or by an external analog voltage. STEP input
starts and stops the motor. DIR input controls direction
of rotation. SPEED input selects the speed range.
The PDO5580 also provides a Tach Output and Enable
Input.
A Tach Out signal is provided for measuring the motor
speed. It generates 100 pulses per revolution. If connected
to a frequency counter, speed reads out in revs/
second with two decimal places.
ENABLE allows the user to turn off the current to the
motor by setting this signal to logic 0. The logic circuitry
continues to operate, the drive “remembers” the step
position even when the amplifier is disabled.
Factory set to operate at 110-volt input; the PDO5580
can be reset by the user to operate at 220-volt input by a
simple switch selection.
Pluggable screw terminal blocks are provided for the
motor, AC input and 8-position signal input/output. Mating
connectors are provided with the drive.
The PDO5580 is both CE and TUV compliant.
