CJ1M-CPU2@
Built-in Output Specifications
Position Control and Speed Control
Variable-duty Pulse Outputs (PWM)
Note: CJ1M CPU Unit Ver. 2.0 or later only. (0% to 100%, set in 1% units for Pre-Ver. 2.0 CPU Units.)
Hardware Specifications
Input Specifications
Count value
Linear mode: 80000000 to 7FFFFFFF hex
Ring mode: 00000000 to Ring SV
(The Ring SV is set in the PLC Setup and the setting range is 00000001 to FFFFFFFF hex.)
High-speed counter PV
storage locations
High-speed counter 0: A271 (leftmost 4 digits) and A270 (rightmost 4 digits)
High-speed counter 1: A273 (leftmost 4 digits) and A272 (rightmost 4 digits)
Target value comparison interrupts or range comparison interrupts can be executed based on these PVs.
Note: The PVs are refreshed in the overseeing processes at the beginning of each cycle. Use the PRV(881) instruction to read the
most recent PVs.
Control
method
Target value
comparison
Up to 48 target values and corresponding interrupt task numbers can be registered.
Range
comparison
Up to 8 ranges can be registered, with an upper limit, lower limit, and interrupt task number for each.
Counter reset method
Phase-Z + Software reset: Counter is reset when phase-Z input goes ON while Reset Bit is ON.
Software reset: Counter is reset when Reset Bit goes ON.
Reset Bits: High-speed Counter 0 Reset Bit is A53100, Counter 1 Reset Bit is A53101.
Item Specifications
Number of pulse outputs 2 (Pulse output 0 or 1)
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 deceleration rates can be set separately only with PLS2(887).
Changing SVs during
instruction 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
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)
The PVs are refreshed during regular I/O refreshing. PVs can be read to user-specified words with the PRV(881) instruction.
Item Specifications
Number of PWM outputs
CJ1M-CPU22/23: 2 (PWM output 0 or 1)
