- 1. Network Based Motion Control
- A maximum of 254 axes can be operated from a PC/PLC through Ethernet communications. And daisy-chain connection is available through internally equipped Ethernet HUB. All of the Motion conditions are set through the network and saved in Flash ROM as a parameter. Motion Library(DLL) is provided for programming under Windows 7/8/10.
- 2. Position Table Function
-
Position Table can be used for motion control by digital input and output signals of host controller. You can operate the motor directly by sending the position table number, start/stop, origin search and other digital input values from a PC/PLC.
The PC/PLC can monitor the origin search complete, moving/stop, step ready and other digital output signals from a drive. A maximum of 256 positioning points can be set from PC/PLC. 
- 3. Microstep and Filtering(High precision Microstep function and Filtering)
- The high-performance MCU operates at step resolutions of 1.8 ° up to maximum 0.0072 ° (1/250 steps) and Ezi-STEPⅡ adjusts PWM control signal in every 50 μsec, which makes it possible for more precise current control, resulting in high-precision Microstep operation.
- 4. Software Damping(Vibration suppression and high-speed operation)
-
Vibration suppression and High-speed operation (Patent pending) Motor vibration is created by magnetic flux variations of the motor, lower current from the drive due to back-emf from the motor at high speeds and lowering of phase voltages from the drive.
Ezi-STEPⅡ drive detects these problems and the MCU adjusts the phase of the current according to the pole position of the motor, drastically suppressing vibration. This allows the smooth operation of the motor at high speeds. 
- ※ This is real measured speed that using 100,000 [pulse/rev] encoder.
