A/D converter: Speed:
4000 times/sec. (max.) when one input is used.
2000 times/sec. (max., X-axis measurement)
when two inputs are used.
Changeable to 100, 200, 500, 1000, 2000 times/sec.
according to the input waveform.
Resolution:
Approx. 1/26000 relative to 20mA
23-2. Pulse Input Section
(When the option is mounted, the analog input becomes exclusive to Y-axis
measurements.)
Maximum input frequency: 50kHz
Internal counting range: 0 ~ 65535. However, a dividing function of 1/4, 1/16 or 1/
64 can be added in the prestage of the counter by setting.
External supply power: 5V DC (150mA max.)
Applicable sensor: The specifications of the sensor connectable to this option
are as follows:
Output:
Incremental type two-phase output (A and B signal output)
Also adaptable to one-phase output.
(The A-phaseinput is used. Pulses are all counted as in the
positive direction.)
Output stage circuit specifications:
1. Open collector
(NPN type, Vceo=10V or more. Ice=30mA or more.)
2. Line driver (In accordance with the RS-422.)
23-3. Display Section

Display area: 118.2W × 89.4H [mm]
Dot
configuration:
320 × 240 [dot]
Dot pitch: 0.12W × 0.36H [mm]
Measured value display: 4-digit
Sign:
Only a negative sign is displayed at the first digit of
the measured value display.
Display rate: 0.1 ~ 9.9 sec./display update selectable
(There is no connection with the A/D conversion speed.)
Increment: Setting in the range of 1 ~ 100.
