STAC6, AC Advanced Microstep Drive

The STAC6-C 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-C 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-C 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. For connecting to external devices such as limit switches, proximity or photoelectric sensors, PLC I/O, lamps, and other devices, the STAC6-C stepper drive comes with 7 digital inputs, 3 digital outputs, and 2 single-ended analog inputs (analog inputs can be wired together as 1 differential analog input). The STAC6-C stepper drive comes with an RS-232 port for configuration and programming. It also comes with a CANopen port for connecting to the CANopen data network. 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-C is UL Recognized (File No. E310506), CE approved, and RoHS compliant.
