Functions and
settings
Origin search Origin proximity input signal: selectable (absent, N.O. or N.C. contact).
Origin input signal: selectable (N.O. or N.C. contact)
Origin compensation: -1,073,741,823 to 1,073,741,823 pulses
Origin search speed: High-speed or proximity-speed can be set.
Origin detection method: May be set to stop upon origin input signal after proximity input
signal has turned ON, to stop upon origin input signal after proximity input signal has
turned OFF, to stop upon origin input signal without using proximity input signal, or to stop
upon origin input signal after limit input signal has turned OFF.
N.O. = Normally open
N.C. = Normally closed
Jogging Jogging can be executed at a specified speed.
Dwell times 19/axis can be set from 0 to 9.99 s (unit: 0.01 s).
Acceleration/
deceleration curves
Trapezoidal or S-curve (Can be set separately for each axis.)
Zones Zone Flag turns ON when present position is within a specified zone. Three zones can be
set for each axis.
Software limits Can be set within a range of -1,073,741,823 to 1,073,741,823 pulses.
Backlash
compensation
0 to 9,999 pulses. Compensation speed can also be set.
Teaching With a command from the PLC, the present position can be taken as the position data.
Deceleration stop The STOP command causes positioning to decelerate to a stop according to the specified
deceleration time.
Emergency stop Pulse outputs are stopped by an external emergency stop command.
Present position
preset
The PRESENT POSITION PRESET command can be used to change the present position
to a specified value.
Override When the override enabling command is executed during positioning, the target speed is
changed by applying the override coefficient. Possible to set to a value from 1 to 999% (by
an increment of 1%)
Data saving 1) Saving to flash memory. (Can be written 100,000 times.)
2) Reading from PLC area by data reading instruction.
3) Reading by Support Software and saving to personal computer hard disk or floppy disk.
External I/O Inputs Prepare the following inputs for each axis:
CW and CCW limit input signals, origin proximity input signal, origin input signal, emergency
stop input signal, positioning completed signal, interrupt input signal
Outputs Prepare the following outputs for each axis:
Pulse outputs
CW/CCW pulses, pulse outputs and direction outputs can be switched.
Either error counter reset or origin-adjustment command outputs can be selected
depending on the mode.
Pulse output distribution period 1-axis operation: 4 ms
Linear interpolation: 8 ms
Response time Refer to Operation manual Appendix A Performance Characteristics.
Self-diagnostic function Flash memory check, memory loss check, CPU bus check
Error detection function Overtravel, CPU error, software limit over, emergency stop

*1. The additional functions supported by unit version 2.0 can be used only when the PCU is installed with a CJ1-H or
       CJ1M CPU Unit (either CPU Unit Ver. 2.0 or Pre-Ver. 2.0 CPU Unit). These functions cannot be used if the PCU is
       installed with a CJ1 CPU Unit.
*2. When performing linear interpolation, the distances that can be moved will vary.
