The STAC6-Si-220 stepper drive is a powerful, two-phase, bipolar step motor
drive for high-speed, high-torque applications. It employs
sophisticated current control designed for optimal smoothness over a
wide speed range. Anti-resonance, torque ripple smoothing, and
microstepping work together to bring step motor performance to a new
high.
The STAC6-Si-220 operates on single-phase 220 VAC and outputs up to
3.2 A/phase (peak-of-sine) to the step motor. It features over-voltage,
over-temperature, and over-current protection and is complemented by a
specially matched set of low-loss NEMA 23 and NEMA 34 frame step motors.
The STAC6-Si-220 can operate in all of the same control modes as a Q
drive, plus it has the ability to run stand-alone Si programs 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.
For connecting to external devices such as limit switches, proximity
or photoelectric sensors, PLC I/O, lamps, and other devices, the
STAC6-Si-220 stepper drive comes with 15 digital inputs and 7 digital
outputs.
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 STAC6-Si-220 stepper drive comes with an RS-232 port for
configuration and programming. It also provides an RS-485 port for
streaming serial (SCL) and Q commands in single-axis applications when
used in the SCL or Q Program control modes.
Each STAC6 drive 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.
The STAC6-Si-220 is CE approved and RoHS compliant.
