The ST5-Si-NN stepper drive is a DC-powered microstepping drive for controlling two-phase, bipolar step motors. It offers advanced current control and a sophisticated 3rd generation anti-resonance algorithm that electronically dampens motor and system resonances to improve motor smoothness and usable torque over a wide speed range. The drive also employs electronic torque ripple smoothing and microstep emulation to greatly reduce motor noise and vibration. The drive must be powered from 24-48 VDC and can output up to 5.0 A/phase (peak-of-sine) to the step motor. Over-voltage, over-temperature and over-current protection features prevent damage while running in adverse conditions. The drive is complemented by a specifically matched set of NEMA 11 through NEMA 23 frame stepper motors (see Related and Recommended products below).
The ST5-Si-NN can operate in all of the same control modes as the Q models, plus it has the ability to run a stand-alone Si program stored in non-volatile memory. Si programs are created using the Si Programmer™ software, which provides unparalleled simplicity in indexer-drive programming via Applied Motion’s unique and powerful icon-based programming environment. Preconfigured motor setup files included with Si Programmer™ make it easy to set up the drive for optimum results.
For connecting to external devices such as control signals, incremental encoders, limit switches, proximity or photoelectric sensors, PLC I/O, lamps, and other devices, the drive comes with 8 digital inputs and 4 digital outputs. Adjustable digital filters are present on the digital inputs for enhanced reliability in noisy environments. Note: 2 single-ended analog inputs, which can be wired together as 1 differential analog input, are also available, but not in Si program mode.
The drive comes with an RS-232 port for configuration and programming.
All ST drives are CE approved and RoHS compliant.
