The ST10-Si-NE 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-Si-NE 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.
The ST10-Si-NE 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.
