Parker: Stepper Drive (OEM650)

The OEM650 Drive is intended to be a high-performance basic engine around which the original equipment manufacturer (OEM) designs his motion control system. Its single-power DC input makes it a convenient and cost effective motion control module. The drive offers a basic set of customer configurable features. These features are designed to meet the needs of most customers. The OEM650 is optimized to operate size 23 and 34 motors.

The OEM650 is a bipolar, recirculating, microstepping drive designed to drive two-phase permanent magnet hybrid step motors. The drive uses a custom ASIC, surface mount, and MOSFET technologies to give high performance in a small package while providing short circuit protection. The OEM650 is compatible with all Compumotor indexers.

The mechanical design is a fully enclosed product that uses a heatplate technique to provide a heat dissipation path. The user must attach the OEM650 module to a suitable mounting surface.

OEM650/ OEM650X Features:

• Microprocessor controlled microstepping provides smooth operation over a wide range of speeds.

• Full short circuit protection for phase-to-phase and phase-to-ground short circuits.

• Motor regeneration protection

• Over-temperature protection

• Uses low-inductance motors for improved high-speed performance (23, 34 frame size motors available with torques from 65 - 400 oz-in).

• Three-state current control for reduced motor/drive heating

• LED status indicators: POWER and FAULT (latched)

• Optically coupled step, direction, and shutdown inputs are compatible with all Compumotor indexers (25-pin D connector).

• A fault output to signal other equipment if a fault occurs

• 24VDC - 75VDC single power input

• 16 jumper selectable motor resolutions (200 - 50,800 steps/rev)

• 2 Mhz step input

• Waveform correction and phase offset for improved smoothness.

• Built-in indexer (position controller)

• -M2 option allows users to store programmed sequences in nonvolatile memory

• I/O for motion and basic machine coordination
