Pulse Outputs Section 7-6
Pulse output
operation mode
(Only in
Independent Mode)
Description Compatible instructions
(1)
Relative pulse output
Positions to a relative position from the present position.
The number of output pulses (actual output amount) in
the specified direction is the target number of pulses.
• The frequency can be changed during pulse output.
• The direction and the target number of pulses cannot
be changed during pulse output.
PULS(886) + SPED(885) or
PULS(886) + ACC(888)
(PULS(886) sets the number of pulses
and SPED(885) or ACC(888) starts the
pulse output.)
PLS2(887)
(Sets number of pulses and starts
pulse output.)
(2) (3)
Absolute pulse out-
put
Positions to an absolute position from the origin.
The number of output pulses is calculated automatically
from the difference between the present position (pulse
output PV) and target pulse amount.
Number of output pulses (actual output amount) =
|Present position − Target position|
• The frequency can be changed during pulse output.
• The direction and the target number of pulses cannot
be changed during pulse output.

(2) Linear mode Operates as linear counter with pulse
output values ranging from 8000 0000
to 7FFF FFFF hex.
Same as for (1).
(3) Circular
mode
Operates as circular counter with pulse
output values ranging from 0000 0000
to the circular value.
When the pulse output PV exceeds the
circular value, it is automatically
returned to 0000 0000. Conversely,
when the pulse output PV is decre-
mented from 0000 0000, it is automati-
cally returned to the circular value.
PULS(886) + SPED(885) or
PULS(886) + ACC(888)
(PULS(886) sets the number of pulses
and SPED(885) or ACC(888) starts the
pulse output.)
(4)
Electronic cam con-
trol (linear)
(5)
Electronic cam con-
trol (circular)
Positions to an absolute position from the origin.
The difference between the present position (pulse output
PV) and target pulse amount is calculated automatically.
Number of output pulses (actual output quantity) =
|Present pulse position − Target position|
• The direction is recognized automatically (CW direction
when the present position < target position, and CCW
direction when the present position > target position).
• The frequency and target position can be changed dur-
ing pulse output. The pulse output will stop if the direc-
tion is changed during pulse output.
PULS(886) (Sets the number of pulses
and starts the pulse output.)
ACC(888)
PLS2(887)
