- 1. CC-Link Based Motion Control
Ezi-STEPⅡ CC-Link is a stepping motor control system that supports CC-Link with high speed fieldbus (max.10Mbps). Ezi-STEPⅡ CC-Link is a remote device module supporting CC-Link network. Multi-function control is possible by occupying 1 station and 2 station in CC-Link, and motion and monitoring functions are processed by device commands.
- 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.
- 5. Improvement of High-Speed Driving
Depending on the speed of a stepping motor, Ezi-STEPⅡ automatically increases the supply voltage and prevents the torque lowering due to the low operating voltage to the motor caused by back-emf voltage, this enables high-speed operation. Additionally, the software damping algorithm minimizes the vibration and prevents the loss-of-synchronization at high-speed.
