Pulse outputs 0, 1: 1 Hz to 100 kHz (1 Hz units)
J models : 1Hz to 20kHz (1Hz units)
Set in 1 Hz units for acceleration/deceleration rates from 1 Hz to 65,635 Hz (every 4
ms). The acceleration and deceleration rates can be set independently only with
PLS2(887).
The target frequency, acceleration/deceleration rate, and target position can be
changed.
Fixed at 50%
CW/CCW inputs or Pulse + direction inputs
The method is selected with an instruction operand. The same method must be used
for pulse outputs 0 and 1.
Relative coordinates: 0000 0000 to 7FFF FFFF hex
(Each direction accelerating or decelerating: 2,147,483,647)
Absolute coordinates: 8000 0000 to 7FFF FFFF hex
(−2147483648 to 2147483647)
Absolute coordinates are specified automatically when the origin location has been
determined by setting the pulse output PV with INI(880) or performing an origin
search with ORG(889). Relative coordinates are used when the origin location is
undetermined.
The pulse type can be specified with an operand in PULS(886) or PLS2(887).
Note The absolute pulse specification can be used when absolute coordinates are specified for
the pulse output PV, i.e. the origin location has been determined.
The absolute pulse specification cannot be used when relative coordinates are specified,
i.e. the origin location is undetermined. An instruction error will occur.
Pulse output 0: A277 (leftmost 4 digits) and A276 (rightmost 4 digits)
Pulse output 1: A279 (leftmost 4 digits) and A278 (rightmost 4 digits)
The PVs are refreshed during regular I/O refreshing.
Trapezoidal or S-curve acceleration/deceleration
There are two pulse output modes. In independent mode the number of out-
put pulses is specified and in continuous mode the number of output pulses is
not specified.

Description
This mode is used for positioning.
Operation stops automatically when the preset num-
ber of pulses has been output. It is also possible to
stop the pulse output early with INI(880).
This mode is used for speed control.
The pulse output will continue until it is stopped by
executing another instruction or switching the PLC to
PROGRAM mode.
