Set Number of Pulses
Specify the number of pulses to be output in independent mode.
Port specifier (000: Pulse output 0; 010: Pulse output 1)
Type of Pulse Output (000: Relative pulses; 001: Absolute pulses) (See note.)
Beginning word of setting for number of pulses
Rightmost 4 digits
Leftmost 4 digits
Number of pulses (Rightmost, leftmost digits)
Register the number of pulses to be set.
96,777,215 to 16,777,215
Negative numbers are expressed by turning ON
the leftmost bit.
Type of Pulse Output
000:
Relative pulses (SV for number of pulses = Number of pulses moved)
001:
Absolute pulses (SV for number of pulses = The next PV on the absolute coordinate system,
i.e., the pulse output PV + number of pulses moved)*
*Absolute pulses can only be specified by PULS(65) when the PV coordinate system
in the PC Setup is set for an absolute coordinate system.
