Product Details

The STAC5-S-N120 stepper drive employs sophisticated current control designed for optimal smoothness over a wide speed range. Anti-resonance, torque ripple smoothing, and microstepping work together to bring step motor performance to a new high. To complement the drive Applied Motion offers a specially matched set of low-loss NEMA 23 and 34 frame motors , all specifically designed with high voltage operation in mind. Power to the drive comes from single-phase 120 VAC, and the drive can output up to 5.0 A/phase (peak-of-sine) to the step motor. Protection features like over-voltage, over-temperature, and over-current prevent damage while running in adverse conditions.

The STAC5-S-N120 can operate in pulse & direction, velocity, and streaming serial (SCL) control modes. Selecting the control mode, setting up the motor, and configuring other drive parameters is done with the ST Configurator™ software.

For connecting to external devices such as limit switches, proximity or photoelectric sensors, PLC I/O, lamps, and other devices, the drive comes with 4 digital inputs, 2 digital outputs, and 1 analog input. The drive also features an Ethernet port for configuration and communications. The Ethernet port is fast 10/100 Mbit, and the drive supports both TCP and UDP communication protocols.

This step motor drive is UL Recognized (File No. E332730), CE approved, and RoHS compliant.
