Number of Remote I/O Connections

The Position Control Unit has the memory of up to 640 bytes for inputs and 640 bytes for outputs to be used for PDO communications.
The number of slaves that can be connected to the CJ1W-NC482/NC882/NCF82 is determined by the maximum memory size for PDO communications.
The memory of the PDO communication is shared with the Servo Drives; therefore, the number of I/O slaves that can be connected changes with the number of G5 Series Servo Drive (number of use axes) that are connected to the Position Control Unit.

Number of Servo Drive axes	Size used by Servo Drive axes (bytes) *	Remaining PDO communications memory size (bytes)		Number of slaves that can be connected according to slave I/O size (guidelines)

Functional Specifications

The following functions are supported when the Position Control Unit is connected to an EtherCAT-compatible OMNUC G5-series Servo Drive.

Function			Description
Control functions	Single axis control	Absolute movements	Positioning is performed by specifying the absolute or relative target position and target speed directly from the ladder program.
		Relative movements
		Speed control	Feeding at a specified speed is performed by specifying the target speed directly from the ladder program. Speed control is implemented using speed feeding with position control.
		Interrupt feeding	Interrupt feeding can be used to move a specified amount when an interrupt input is received during an absolute movement, a relative movement, or speed control.
		Rotation axis control	Rotation axes that are suitable for feeder and index table control can be controlled. Forward and reverse positioning and shortest route operations are possible.
		Changing target positions and target speeds	The target position or target speed can be changed during an absolute movement, a relative movement, or speed control.
	Multi-axis control	Linear interpolation	The operation of more than one axis is started and stopped simultaneously to move in a straight line to the target position from the starting point of each axis. Linear interpolation is possible for up to four axes.
		Circular interpolation	The operation of any two axes is controlled to move in a circular arc. Any of three methods can be used to specify a circular arc: specifying the target position and center point, specifying the target position, radius, and direction and specifying the target position and passing point.
		Helical interpolation	Helical interpolation is performed by giving one more axis to circular interpolation. The number of turns can be specified. This function is available with CJ1W-NC[]82 (unit version 1.5 or later).
	Memory operation	Automatic continuous operation	The target positions, speeds, and operation patterns can be set in advance in the Position Control Unit to automatically perform a series of operations. Continuous positioning and speed changes are also possible.
	Memory operation	Sequence functions	Memory operation data provides sequence functions, including repetition of a given operation and starting/stopping operation data by using external inputs. Therefore, the Position Control Unit can perform various operation sequences without affecting the ladder programming in the CPU Unit.
Manual operation	Origin searches		External sensors and other means are used to detect the mechanical origin of the system. You can select the origin search operation that is best for your system from 15 different origin search operation patterns.
	Origin returns		You can return to the point that was defined as the mechanical origin.
	Presetting the present position		The present position can be changed to a specified value to define the origin.
	Deceleration stops and emergency stops		An axis that is in operation can be decelerated to a stop or stopped immediately.
	Jogging		You can jog either forward or in reverse.
	Inching		You can inch either forward or in reverse.
Synchronous Data Link			The CJ1W-NC[]82 (unit version 1.3 or later) can perform data exchange between the CPU and Position Control Unit at regular intervals when used in conjunction with a CJ2H CPU (unit version 1.4 or later). In addition, you can use this function to perform synchronous feeding position, synchronous feeding velocity, and synchronous feeding torque control. Also, optional commands are available for torque feedforward data, torque limit data, and velocity limitation value. CJ1W-NC[]82 (unit version 1.5 or later) supports command for electronic cam operation as well.
Auxiliary control functions	Command unit setting		You can set the unit of control for each axis according to the machine.
	Acceler- ation/ deceler- ation control	Automatic acceleration/ deceleration control	The acceleration/deceleration curve can be automatically created during operation. You can select either a trapezoidal curve or an S curve based on a tertiary function.
		Changing acceleration/ deceleration rates	You can change the rate of acceleration/deceleration during acceleration/deceleration.
		Switching acceleration/ deceleration points	You can select one of three methods to connect speeds between different operation patterns during continuous memory operation.
	Overrides		You can increase or decrease the operating speed of the system by a specified factor.
	Backlash compensation		You can compensate for mechanical play using a parameter.
	M codes		M codes can be output during memory operation to interlock with external devices.
	Zone settings		You can set zones and assess when the present position is in a zone. Up to three zones can be set for each axis.
	Support for absolute encoders		You can build an absolute positioning system by using a Servomotor with an Absolute Encoder. The Position Control Units can be used together with OMRON's G5-series Servomotors with Absolute Encoders.
	Teaching		You can save the present position as position data for memory operation.You can use either the command present position or feedback present position.
	Torque limit outputs		The torque limit outputs can be used to switch the torque limits of the Servo Drive. They can be turned ON and OFF directly from a ladder program. Torque limits can be automatically switched by using holding for an origin search operation. In addition, you can change the torque limit data via the Synchronous Data Link by using the CJ1W-NC[]82 (unit version 1.3 or later) in conjunction with a CJ2H-CPU (unit version 1.4 or later) and G5-series Servo Drive (version 2.0 or later). Also, you can change the torque limit data via the Memory Area by using the CJ1W-NC[]81/-NC[]82 (unit version 1.3 or later) in conjunction with a G5-series Servo Drive (version 2.0 or later).
	Monitoring functions	Software limits	You can set forward and reverse software limits for axis operation. If the target position exceeds a software limit, it will be detected in the command value check that is performed at startup.
		Monitoring position/ speed deviations	The Position Control Unit monitors the position or speed deviation between the present command position and present feedback position. You can stop axis operation if the deviation is too large.
		Monitoring deviation between axes	The deviation between axes is also monitored during linear interpolation. You can stop axis operation if the deviation is too large.

Functions available when connected with OMRON encoder input terminal GX-EC02[]1 are as shown below.
They are available with CJ1W-NC[]82, unit version 1.5 or later.

Function		Description
Manual operation	Present position preset	The present position can be changed to a specified value to define the origin.
Auxiliary control functions	Command unit setting	You can set the unit of control for each axis according to the machine.
	Zone settings	You can set a zone to check if the present position is in the set zone. Up to three zones can be set for each axis.
	Present position latch	The position data when an external control input (latch A) is detected at the encoder input terminal is stored in the Position Control Unit.
	Origin position latch	The position data when an external control input (latch B) is detected at the encoder input terminal is stored in the Position Control Unit.
