The PDO2035 stepper drive is packaged in a rugged steel case. Integral heat sink, mounting brackets, and connectors are included with each drive. The drive comes factory set for 110 VAC operation, but can be switched to operate on 220 single-phase VAC as well. The drive is recommended for use with NEMA 11, 14, 17, and 23 frame step motors to create a complete stepper motion solution. Pluggable mating screw terminal blocks are provided with each drive for connecting the motor, AC input, and I/O.
The PDO2035 provides the user with two modes of operation to choose from, Pulse & Direction or Oscillator, selectable during set up via DIP switch. DIP switches are also provided for setting the step resolution and motor current. Pulse & Direction mode allows the PDO2035 to receive step pulses from an indexer, motion controller, PLC, or other external controller. Oscillator mode controls the speed of the motor relative to an on-board potentiometer. An external analog voltage or potentiometer may also be used to control speed. In oscillator mode the STEP input starts and stops the motor, while the DIR input controls direction of rotation.
The PDO2035 also provides a tach output and an enable input. The tach output provides a means for measuring motor speed. It generates 1 pulse per motor step. The enable input allows the user to turn off the motor current with a digital signal. When the enable input is activated the drive cuts power to the motor, which means the motor is disabled and has no torque.
