Production introduction
AS850T is a new tailor made spindle controlling frequency inverter for CNC, machining center, packing, textile, etc. It can achieve to high accuracy speed, torque and position control through close loop servo control, which based on brand new hard ware and soft ware platform.
Perfect performance and powerful function is your machine best selection.
Function features
Rigid tapping, C axis function, accuracy stop control, 0 speed lock, Electronic CAM, pulse synchronous, index plate function, and big torque cutting when low speed.
Points position control
The pulse can be set by functional code, even no pulse command, the position control of fix route can set by external terminal as well.
Pulse synchronization position control
To achieve high accuracy continuous route control by pulse train, also can realized multiple motor synchronous speed control by pulse train.
Reduce the speed response effectively by variable gain control. Compare to previous products, the deceleration time reduce sharply.
Zero speed servo control
It will automatically go to 0 speed servo control status and keep still when motor speed low to 0 value. AS850T can output 180% rated torque output with PG connection.
Electric gear
Through gear ratio of electric gear setting, can set motor movement value that equivalent to input pulse freely. Configure 4 groups electric gear, it can be set freely by terminal configuring.

Software funciton
| Function | Application | Purpose | function describe |
| points positioning | mechanical transmission | auto process control | The servo motor will run when receiving a command, and move to setting point. When arriving the set point, it will stop and sent a signal back |
| reciprocating position running | mechanical transmission | auto process control | Perform reciprocating movement between two points, the speed can be set. |
| multiple points positioning | mechanical transmission | auto process control | Up to 256 points can be set. When corresponding input signal is valid, motor will move to that point. |
| synchronous driving | mechanical transmission | synchronous speed control | The motor speed swill synchronize with the input pulses, the synchronize ratio can be set. Used in print and textile. Etc filed |
| torque control | pressing machine | output torque adjustable | The motor torque can be adjusted by analog input or communication method. Ensure every motor has the same torque |
| cut to length | transverse cutter, | auto to realize fixed length cutting | The drive will measure the cutting length by external encoder, and calculate the initial point, it will activate cutting when arriving the cutting length. |
| parallel drive | roller rail | to realize same output | To achieve the same output for every motor when multiple drives serving a load by communication mode. |
