AMD Series - AC Asynchronous Spindle Servo Drives

AMD  series spindle servo drive is designed for numerical control machine of  new type and high precision and it has new functions like positioning  control, pulse synchronous control and so on. It supports close loop  control towards the spindle motor with encoder. This drive has high  respoonding ability towards speed as well as smooth speed. 

It can achieve various functions like warrant stop of spindle, rigid  tapping, indexing positioning and so on by cooperating with different  numerical control system.

Features

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 ips.

  • 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.

Power dip ride throughThe load feedback energy compensates the voltage reduction so that  the AC drive can continue to run for a short time
Overvoltage/overcurrent stall controlThe current and voltage are limited automatically during the  running process so as to avoid frequent tripping due to over voltage/over  current
Torque limit and controlIt can limit the torque automatically and prevent frequent over  current tripping during the running process. Torque control can be  implemented in the FVC mode.
Onboard multiple preset speedsIt implements up to 16 speeds via the simple PLC function or  combination of X terminal states
