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.
