The ST5-C-CE 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-C-CE is designed to operate on a CANopen communication network and conforms to Can in Automation

(CiA) DS301 and DSP402 specifications. It supports Profile Position, Profile Velocity, and Homing modes, as well

as the ability to run stored Q programs via Applied Motion-specific CANopen objects. The drive is setup and

configured using Applied Motion’s ST Configurator™ software. Preconfigured motor setup files included with ST

Configurator™ 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, 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.

The drive comes with an RS-232 port for configuration and programming. It also comes with a CANopen port for

connecting to the CANopen data network.

The ST5-C-CE 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.
