Function features
Software function
| 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. |
Main features of AS850 Servo Drive
Points positioning 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.
