The
STM17Q-3AE integrated stepper is a drive+motor unit, fusing a NEMA 17
step motor and a sophisticated 2.0 A/phase (peak-of-sine) stepper drive
into a single device. Power to the drive, located at the rear of the
motor, must be supplied by an external DC supply. See Related and
Recommended Products below for compatible 24 and 48 volt DC
power supplies.
The STM17Q-3AE integrated stepper can operate in all of the same
control modes as the S option, plus the ability to run a Q program
stored in non-volatile memory. Q programs are created using Applied
Motion’s
Q programmer™
software, which provides powerful commands for motion, I/O, conditional
processing, multi-tasking, math functions, and more. All STM17 units
are setup and configured using Applied Motion’s
ST Configurator™ software.
An integral 1000-line (4000 count/rev) incremental encoder is housed
inside the same enclosure as the drive electronics, providing protection
from dust and debris. The integration of the encoder means the
STM17Q-3AE can perform special functions not available otherwise. 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 actually
prevents stalling of the step motor by dynamically adjusting 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 available to step motors,
such as torque-control applications. The Stall Prevention feature also
performs static position maintenance, which maintains the position of
the motor shaft when at rest.
Each STM17 integrated stepper comes with 3 digital inputs, 1 digital
output, and 1 analog input. The digital inputs accept signals of 5-24
VDC and can be used for connecting pulse & direction signals,
end-of-travel limit switches, jog switches, quadrature encoder signals,
PLC outputs, sensors, or many other signal types. The digital output
can be connected to PLC inputs, counters, lights, relays, or other
devices. The analog input accepts 0-5 VDC signals and can be used for
velocity and position control.
The STM17Q-3AE comes with an RS-232 port for programming and serial communications.
