The STAC6-Si 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 operates on single-phase 120 VAC and outputs up to 6.0 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 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 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 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 is UL Recognized (File No. E310506), CE approved, and RoHS compliant.
