The ST10-IP-EE 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 24-80 VDC and can output up to 10.0 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 23 and NEMA 34

frame stepper motors (see Related and Recommended products below).

The ST10-IP-EE 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.

The ST10-IP-EE comes with an encoder feedback connector for applications that demand a higher level of

position control than ordinary open-loop step motor systems can provide. Use our double-shaft step motors with

incremental encoders and activate either Stall Detection or Stall Prevention in the drive. Stall Detection notifies the

system as soon as the required torque is too great for the motor, which results in a loss of synchronization

between the rotor and stator, also known as stalling. Stall Prevention automatically adjusts motor speed to

maintain synchronization of the rotor to the stator under all conditions. This unique feature allows step motors to

operate in a much broader range of applications than previously possible, such as torque-control. The Stall

Prevention feature also performs static position maintenance, which maintains the position of the motor shaft when

at rest. Additionally, the inclusion of the optional encoder allows the motor to be precisely homed to the index

(marker) pulse.

All ST drives are CE approved and RoHS compliant.
