Functions
and settings		Origin searchOrigin 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
JoggingJogging can be executed at a specified speed.
Dwell times19/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.)
Functions
and settings		ZonesZone Flag turns ON when present position is within a specified zone.
Three zones can be set for each axis.
Software limitsCan 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.
TeachingWith a command from the PLC, the present position can be taken as the
position data.
Deceleration stopThe STOP command causes positioning to decelerate to a stop according
to the specified deceleration time.
Emergency stopPulse 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.
OverrideWhen 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 saving1) 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/OInputsPrepare 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
OutputsPrepare 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 period1-axis operation: 4 ms
Linear interpolation: 8 ms
Response timeRefer to Operation manual Appendix A Performance Characteristics.
Self-diagnostic functionFlash memory check, memory loss check, CPU bus check
Error detection functionOvertravel, CPU error, software limit over, emergency stop

Note:

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.

Caution: In the interenst of product improvement, specifications are subject to change without notice.
