Since the output phase difference is 90
°±
45
°
, the minimum phase difference
produced by this encoder is as follows:
90
°
– 45
°
= 45
°
Because the C200H-CT001-V1 requires a minimum phase difference of 4.5 4.5
must be less than 45
°
/360
°
. T must therefore be less than 36 meaning the maxi-
mum frequency, 1/T, would be 27.7 kcps (54 rps for 500 pulses per revolution).
This would be the maximum frequency at which this encoder could be used with
the C200H-CT001-V1. With the C200H-CT002, a minimum phase difference of
3 is required. Computing as above shows a maximum frequency of 41.7 kcps
when using the C200H-CT002 with this encoder.
Note The minimum pulse width must be considered when using input Z to reset
the counter. With the C200H-CT001-V1, the pulse width of input Z must be
0.1 ms or greater, and the return frequency must be 5 kcps or less. With the
