Description
This stepper drive with model number ending in -NF is designed to accept encoder feedback. Be sure to order a
compatible stepper motor with the encoder option (i.e. -WAA, -ZAA, or -YAA).
The ST10-Q-NF 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-Q-NF can operate in all of the same control modes as the S model (pulse & direction, velocity,
streaming commands, SiNet Hub operation), plus it has the ability to run stand-alone Q programs stored in non-
volatile memory. Q programs are created using the
Q Programmer™
software, which provides multi-tasking, math
functions, conditional processing, data register manipulation, and more features in a robust yet simple text-based
programming language. 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, serial communications and programming.
The ST10-Q-NF includes a quadrature encoder feedback input 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.
The ST10-Q-NF also features a separate, buffered encoder output so that other devices can monitor the motor
position in real time.
All ST drives are CE approved and RoHS compliant.
