6.13 Outline of FCUA-DX13 Unit Pulse Input Circuit
When connecting a pulse generator other than the manual pulse generator (FCUA-HD60) to the
FCUA-DX13
unit, use within the specifications range given below.
Commercially available pulse generators include the 25P/R type and the 100P/R type. A pulse is
multiplied by four internally, so use the 25P/R type.
Input/output conditions
Input pulse signal format
A-phase and B-phase difference 90° (Refer to waveform (e)
below)
Input signal voltage H level 3.5V to 5.25V, L level 0V to 0.5V
Input pulse maximum
frequency
100kHz
Pulse generator power voltage
12VDC ± 10%
Maximum output current 300mA
Number of pulses per rotation 25P/R (FCUA-HD60 is 25P/R)
Input waveform
The phase difference of the input waveform (∆e) must be ±45° or less.
e : A-phase and B-phase difference
∆e : Rising phase error of A phase or B phase (-45° ≤ ∆e ≤ 45°)
T : A or B phase cycle (minimum 10
µs)
