(3)Cable Length Design
Design the length of cables as the sum of voltage drop by K1 and K2 becomes 0.2V or less.
Note that voltage drop of K1 is caused by the total current consumption of High
Resolution Serial Output Circuit C and linear encoder.
［Example of calculation］
Case that HEIDENHAIN LS486C is used and 10m length cable is used for K1.
（Max. Current of HEIDENHAIN LS486C is = 150mA ）
①Voltage drop by K1：Vd
5V,0V
Vd = ( 0.25A+0.15A
)×{ 38.7Ω/km ÷３×(10m×2)÷1000m}
↑ ↑ ↑
Total current(max.) 0.5mm
2
(number of wire)
= 0.1032V
②Maximum length of K2：L2
L2 = ( 0.2V - 0.1032V )÷ 0.15A ÷ ( 38.7 Ω/km
×２÷1000 )
(Note)
= 8.3m
(Note)
The resistance of standard head cable of HEIDENHAIN LS486C.
(The standard LS486C head cable has two wires of 0.25mm

for 5V and 0V respectively. )
