CJ1M Functions Arranged by Purpose Section 1-9
Perform fixed distance
feed interrupt.
Built-in
Outputs
Pulse out-
puts 0 and
1
Execute positioning
with the PLS2(887)
instruction during an
operation started with
SPED(885) (continu-
ous) or ACC(888) (con-
tinuous).
When a speed control operation started with
the SPED(885) instruction (continuous) or
ACC(888) instruction (continuous) is in
progress, the PLS2(887) instruction can be
executed to switch to positioning, output a
fixed number of pulses, and stop.
After determining the
origin, perform position-
ing simply in absolute
coordinates without
regard to the direction
of the current position
or target position.
Built-in
Outputs
Pulse out-
puts 0 and
1
The positioning direc-
tion is selected auto-
matically in the absolute
coordinate system.
When operating in absolute coordinates
(with the origin determined or INI(880)
instruction executed to change the PV), the
CW or CCW direction is selected automati-
cally based on the relationship between the
pulse output PV and the pulse Output
Amount specified when the pulse output
instruction is executed.
Perform triangular con-
trol.
Built-in
Outputs
Pulse out-
puts 0 and
1
Positioning with the
ACC(888) instruction
(independent) or
PLS2(887) instruction.
When a positioning operation started with
the ACC(888) instruction (independent) or
PLS2(887) instruction is in progress, triangu-
lar control (trapezoidal control without the
constant-speed plateau) will be performed if
the number of output pulses required for
acceleration/deceleration exceeds the speci-
fied target pulse Output Amount.
(The number of pulses required for accelera-
tion/deceleration equals the time required to
reach the target frequency x the target fre-
quency.)
Use variable duty ratio
outputs for time-propor-
tional temperature con-
trol.
Built-in
Outputs
PWM(891)
outputs 0
and 1
(CPU21:
PWM out-
put 0 only)
Control with analog
inputs and the variable
duty ratio pulse output
function (PWM(891))
Two of the built-in outputs (bits 04 and 05 of
CIO 2961) can be used as PWM(891) out-
puts 0 and 1 by executing the PWM(891)
instruction.
(CPU21: bits 04 of CIO 2961 only)
