Output mode Continuous mode (for speed control) or independent mode (for position con-
trol)
Positioning (independent mode) instruc-
tions
PULS(886) and SPED(885), PULS(886) and ACC(888), or PULS2(887)
instruction
Speed control (continuous mode)
instructions
SPED(885) and ACC(888) instructions
Origin (origin search and origin return)
instructions
ORG(889) instruction
Interrupt feeding instruction IFEED(892) instruction
Output frequency 1 pps to 100 kpps (1 pps units), two pulse outputs × 2 Pulse I/O Modules
Frequency acceleration and decelera-
tion rates
Set in increments of 1 pps for acceleration/deceleration rates from 1 to 65,535
pps (every 4 ms).
The acceleration and deceleration rates can be set independently only with
the PLS2 instruction.
Internal pulse control cycle 1 ms or 4 ms (Set in the PLC Setup.)
Changing SVs during instruction execu-
tion
The target frequency, acceleration/deceleration rate, and target position can
be changed.
Pulse output method CW/CCW or pulse + direction
Number of output pulses Relative coordinates: 0000 0000 to 7FFF FFFF hex (Accelerating or decelerat-
ing in either direction: 2,147,483,647)
Absolute coordinates: 8000 0000 to 7FFF FFFF hex (−2,147,483,648 to
2,147,483,647)
Relative/absolute coordinate specifica-
tions for pulse output PVs
Absolute coordinates are specified automatically when the origin location has
been defined by changing the pulse output PV with the INI(880) instruction or
performing an origin search with the ORG(889) instruction. Relative coordi-
nates must be used when the origin is undefined.
Relative pulse/absolute pulse specifica-
tions
The pulse type can be specified with an operand in the PULS(886) or
PLS2(887) instruction.
Absolute pulses can be used when absolute coordinates are specified for the
pulse output PV, i.e. the origin location has been defined. Absolute pulse can-
not be used when relative coordinates are specified, i.e., when the origin loca-
tion is undefined. An instruction error will occur.
Pulse output PV's storage location The following Auxiliary Area words contain the pulse output PVs
Pulse output 0: A277 (leftmost 4 digits) and A276 (rightmost 4 digits)
Pulse output 1: A279 (leftmost 4 digits) and A278 (rightmost 4 digits)
Pulse output 2: A323 (leftmost 4 digits) and A322 (rightmost 4 digits)
Pulse output 3: A325 (leftmost 4 digits) and A324 (rightmost 4 digits)
The PVs are refreshed during regular I/O refreshing.
