The ST5-IP-EN 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-IP-EN incorporates EtherNet/IP network communications, the widely used industrial protocol for

manufacturing automation applications. With EtherNet/IP users can control, configure and query the drive using an

open, standards-based, industrial Ethernet connection at speeds up to 100 MBits/sec. The ST-IP drives run all of

the same control modes as ST-Q drives, with the addition that all drive features can be accessed over

EtherNet/IP, including more than 100 commands and 130 registers for controlling motion, I/O, configuration,

polling, math, register manipulation, and Q programming.

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, 4 digital outputs,

and 2 single-ended analog inputs (analog inputs can be wired together as 1 differential analog input). Adjustable

digital filters are present on the digital inputs for enhanced reliability in noisy environments.

In addition to EtherNet/IP the drive supports Ethernet TCP and UDP protocols for sending commands from Applied

Motion’s proprietary Serial Command Language (SCL). The same 10/100 Mbit Ethernet port on the drive is also

used for configuring and programming the drive using the ST Configurator™ and Q Programmer™ software

applications, respectively.

All ST drives are CE approved and RoHS compliant.
