SureStep high-voltage ac drives are available with compatible high-torque motors. The drive is powered from 90 to 240 Vac and is intended for use with step motors designed to handle a high bus voltage of 340 Vdc. MTRAC motors are specially designed to work with high bus voltages, providing higher torque, especially at higher speeds. Stepper drive auto-setup measures motor parameters and configures motor current control and antiresonance gain settings. The drive uses ac input of 90 to 240 Vac. Output current is selectable from 0.6-2.5A/phase (peak of sine). Motors are available in NEMA frame sizes 23 and 34 with torque available from 75 to 1,841 oz-in.
