STATUS LED'S AC power (red).

 

DIGITAL OSCILLATOR Precise speed control with automatic ramps between speeds. The accel/decel rates are set by an on board potentiometer, and are adjustable from 10 to 12,000 steps/sec/sec.
SPEED SETTINGS AND RANGE On-Board: Speed potentiometer. High speed: 100–12,000 steps/sec/sec. Low speed: 10–1,200 steps/sec/sec.
External: External potentiometer capable.
MODES OF OPERATION Two modes dip switch selectable:
Pulse and Direction: works with pulse and direction controllers Oscillator: on-board potentiometers and/or an external 0–5 V analog voltage, control speed.
STEP AND DIRECTION INPUTS Optically isolated: 5–24 VDC. Steps requires a 10 microsecond minimum pulse width. The direction signal setup time is 50 microsecond minimum.

Description

The PDO2035 is stepper drive packaged in a rugged steel case painted black with white epoxy silk screen. Integral heat sink, mounting brackets, switch covers and connectors are included with each drive.

The drive has been matched with nine recommended NEMA 11, 14, 17 & 23 motors in order to create a complete stepper motion
solution.

The PDO2035 provides the user with two modes of operation to choose from, Pulse & Direction or Oscillator. The specific operation mode desired is selected during set up via DIP switch. DIP switches are also provided for setting the drive' s step resolution as well as the motor current.

Pulse & Direction Mode allows the PDO2035 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.

Oscillator Mode can control speed by an onboard potentiometer and/or by an external analog voltage. STEP input starts and stops the motor. DIR input controls direction of rotation.

The PDO2035 also provides a Tach Output and Enable Input.

A Tach Out signal is provided for measuring the motor speed. It generates 1 pulse per motor step. ENABLE allows the user to turn off the current with a signal. 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 PDO2035 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 as well as a 4 and 5 position signal input/output. Mating connectors are provided with the drive.
