Rohnert Park, CA ‚â€“ Parker‚â€™s Electromechanical Automation Division announces the release of the new Compumotor-brand Open Frame Stepper (OFS) microstepping drives.
OFS drives are an economical alternative to more expensive, full-featured, packaged AC powered step drives. The OFS drives deliver all the performance required in a high-value, low-frills approach to motion control.
Although incredibly easy to set up and use, the OFS step drives feature 3-state, PWM, MOSFET H-Bridge technology. Capable of delivering 3.5 amps peak current per phase, the smaller-than-average step drive is capable of driving from size 11 through size 34 step motors.
The OFS is available in two models: the OFS350-DRI, which is a drive-only version requiring step and direction inputs, and the OFS350-OSC, which has basic onboard control capability. Both drives measure just 4‚â€ x 3‚â€ x 1.5‚â€.
Parker complements the release of the OFS drives with a full line of high-value accessories, including the LV step motors and STP power supply. The LV line of low-voltage motors is optimized for high performance at lower DC bus voltages similar to those used with the OFS drives. The LV motors come in frame sizes 11, 17, 23 and 34 in both single and triple stacks. The STP-32PRK4 is a 40VDC, 4A power supply designed and optimized specifically for use with the OFS drives.
