The
STM24C-3CE integrated stepper is a drive+motor unit, fusing a NEMA 24
step motor and a sophisticated, 6.0 A/phase (peak-of-sine) step motor
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 STM24C-3CE integrated stepper 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. All STM24 integrated steppers
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 stepper
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. 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.
The STM24C-3CE comes with 3 digital inputs and 1 digital output. The
digital inputs accept signals of 5-24 VDC and can be used for connecting
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 unit also comes with 1 analog input that accepts 0-5 VDC
signals, which can be used for velocity and position control.
The STM24C-3CE comes with an RS-232 port for programming and a CANopen port for network communications.
