Item Specifications
Output frequency 1 Hz to 100 kHz (1-Hz units from 1 to 100 Hz, 10-Hz units from 100 Hz to 4 kHz, and
100-Hz units from 4 to 100 kHz)
Frequency acceleration and
deceleration rates
Set in 1 Hz units for acceleration/deceleration rates from 1 Hz to 2 kHz (every 4 ms). The acceleration and decel-
eration rates can be set separately only with PLS2(887).
Changing SVs during instruc-
tion execution
The target frequency, acceleration/deceleration rate, and target position can be changed. Changes to the target
frequency and acceleration/deceleration rate must be made at constant speed.
Pulse output method CW/CCW inputs or Pulse + direction inputs
Number of output pulses Relative coordinates: 00000000 to 7FFFFFFF hex (Each direction accelerating or decelerating: 2,147,483,647)
Absolute coordinates: 80000000 to 7FFFFFFF hex (−2,147,483,648 to 2,147,483,647)
Instruction used for origin
searches and returns
ORIGIN SEARCH (ORG(889)): Origin search and origin return operations according to set parameters
Instructions used for position
and speed control
PULSE OUTPUT (PLS2(887): Trapezoidal output control with separate acceleration and deceleration rate
SET PULSES (PULS(886)): Setting the number of pulses for pulse output
SPEED OUTPUT ((SPED(885): Pulse output without acceleration or deceleration (Number of pulses must be set
in advance with PULS(886) for position control.)
ACCELERATION CONTROL (ACC(888)): Changes frequency or pulse output with acceleration and deceleration
MODE CONTROL (INI(880)): Stopping pulse output
Pulse output PV's storage loca-
tion
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)
The PVs are refreshed during regular I/O refreshing. PVs can be read to user-specified words with the PRV(881)
instruction.
Item Specifications
Duty ratio 0% to 100%, set in 0.1% units (See note.)
Frequency 0.1 Hz to 999.9 Hz, Set in 0.1 Hz units.
Instruction PULSE WITH VARIABLE DUTY RATIO (PWM(891)): Sets duty ratio and outputs pulses.
