aSTEM Hybrid Control System
AlphaStep products are stepper motor based hybrid motors with a unique hybrid control system combining the benefits of “open loop control” and “closed loop control”. The position of the motor is always monitored, and then the driver automatically switches between 2 types of control depending on the situation.
Normally Operates in Open Loop Control for the Same Ease of Use as a Stepper Motor
High Response
By utilizing the high responsiveness of the stepper motor, moving a short distance for a short time is possible. The motors can execute commands without lag.
Holding the Stop Position without Hunting
During positioning, the motor stops with its own holding force without hunting. Because of this, it is ideal for applications where the low rigidity of the mechanism requires absence of vibration upon stopping.
Tuning-Free
Because it is normally operated with open loop control, positioning is still possible without gain adjustment even when the load fluctuates due to the use of a belt mechanism, cam or chain drive, etc.
Switches to Closed Loop Control during Overload for More Reliable Operation like a Servo Motor
Continues Operation Even with Sudden Load Fluctuation and Sudden Acceleration
It operates synchronously with commands using open loop control during normal conditions. In an overload condition, it switches immediately to closed loop control to correct the position.
Alarm Signal Output in Case of Abnormality
If an overload is applied continuously, an alarm signal is output. When the positioning is complete, and END signal is output. This ensures the same level of reliability as a servo motor.
