Differential phase pulse input mode, pulse + direction input
mode, up/down pulse input mode, increment mode
Input frequency: 10 Hz to 500 Hz; 20 Hz to 1 kHz; 300 Hz to 20 kHz
Input numbers: 00000, 00001, and 0002
Output numbers: 01000 and 01001
Settings for synchronized pulse control: Input mode, input frequency
SYNC(––): For beginning synchronized pulse control and changing the scaling factor.
INI(61): For stopping synchronized pulse control.
PRV(62): For reading the high-speed counter frequency and the synchronized pulse
control status.
