Pulse Outputs Section 5-2
SET PULSES: PULS(886) PULS(886) is used to set the pulse output amount (number of output pulses)
for pulse outputs that are started later in the program using SPED(885) or
ACC(888) in independent mode.
SPEED OUTPUT:
SPED(885)
SPED(885) can be used to perform pulse output without acceleration or
deceleration. Either independent mode positioning or continuous mode speed
control is possible. For independent mode positioning, the number of pulses is
set using PULS(886).
SPED(885) can also be executed during pulse output to change the output
frequency, creating stepwise changes in the speed.
Operand Contents
P Port specifier 0000 hex: Pulse output 0
0001 hex: Pulse output 1
T Pulse type 0000 hex: Relative pulse output
0001 hex: Absolute pulse output
N First number
of pulses word
N and N+1 contain the number of pulses setting. (N contains
the rightmost 4 digits and N+1 contains the leftmost 4 digits.)
Relative pulse output:
0000 0000 to 7FFF FFFF hex (0 to 2,147,483,647)
Absolute pulse output:
8000 0000 to 7FFF FFFF hex (-2,147,483,648 to
2,147,483,647)
