LINEAR MEASUREMENT ACCESSORIES
-Length measurement and positioning
APPLICATION
DW
DrawWire
The draw wire accessory is used with the encoder for
length measurement and position control applications.
The accuracy is given by the ratio between the draw wire
drum circumference and the encoder resolution, e.g.:
204.8 mm / 8192 CPR = 0.025 mm per code
200 mm / 10000 PPR = 0.02 mm per pulse
