The purpose-designed asynchronous servo axis optimized for asynchronous geared motors. Practical spectrum of functionalities for modern positioning and control drives.
Features
* Multi encoder support: it can support differential encoder; ABZ encoder; Resolver and so on.
* Power dip ride-through, load feedback energy compensates for any voltage reduction, allowing the drive to continue to operate for a short time during power dips.
* Overvoltage and overcurrent stall control: the system limits the output current and voltage automatically during operation to prevent frequent or excessive trips.
* Torque limit and control: the system limits the torque automatically to prevent frequent overcurrent tripping during operation. Torque control is applied in vector control.
* Onboard multiple preset position: the system implements up to 16 position by using simple PLC function or by using digital input signals.
