描述 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.
