Encoder signals input ■
The encoder signals input include two combinations of signal inputs: XEA,XEB and YEA,YEB.
Phase differential signals or pulse signals in independent direction can be input.
Input timing of phase difference signal ● Address counter ●
・ Digital filter initial value (100 ns)
When the multiplier is 2:t1, t2, t3, t4＞ 100 ns
EA input
t1＋ t2＞ 200 ns、 t3＋ t4＞ 200 ns
When the multiplier is 4： t1, t2, t3, t4≧ 200 ns EB input
・ When set to 0 by digital filter applied function
＞ 50 ns t1 t2 t3 t4 When the multiplier is 2:t1, t2, t3, t4
t1＋ t2≧ 200 ns、 t3＋ t4≧ 200 ns
When the multiplier is 4： t1, t2, t3, t4≧ 200 ns
