Functional Specifications

Function item			Description
Control  function	Single  axis  control	Absolute movement	Specify the absolute/relative target position and target speed directly  in the ladder program to perform positioning.
		Relative movement
		Speed control	Specify the target speed directly in the ladder program to perform  speed feed.
		Interrupt Feeding	Externally issue an interrupt input during absolute movement, relative  movement or speed control to feed the machine by a constant amount  to perform positioning.
		Rotational axis  control	Rotational axes suitable for feeder and index table control are  supported. In addition to forward/reverse direction positioning,  you can also specify short-cut operation.
		Target position  and target speed  change	Change the target position or target speed during absolute movement,  relative movement or speed control.
	Multi-  axis  control	Linear  interpolation	This control starts/ends the operations of multiple axes simultaneously  and connects the start position to target position of each axis by a  straight line. Linear interpolation of up to 4 axes is possible.
		Circular  interpolation	You can combine 2 desired axes and control each axis in a manner  which the axes draw a circular path.  Three methods are available to specify a circular arc: "Specification  of target position and center point", "specification of target position,  radius and direction" and "target position and passing points".
	Memory  operation	Automatic  operation and  continuous  operation	Set the target positions, target speeds and operation patterns in the  PCU beforehand to perform a series of operations automatically.  Continuous positioning and speed changes are also possible.
		Sequence function	Memory operation data incorporates a sequence feature that allows for  repetition of a given operation, start/end of operation data via external  inputs, and so on.  Accordingly, the PCU can perform various operation sequences without  affecting the ladder program of PLC.
Manual  operation  function	Origin Search		This function uses an external sensor, etc. to detect the mechanical  origin of the system.  You can select a desired origin search operation for your system from  15 different origin search operation patterns.
	Origin Return		This function performs the return operation to the established  mechanical origin.
	Present Position Present		It changes the present position to the specified data and establishes  the origin.
	Deceleration stop		The operating axis decelerates to a stop.
	JOG Operation		This function feeds the axis in the forward/reverse direction at a  constant speed.
	Inching operation		The axis inches in the forward/reverse direction.
	MPG operation		Connect a manual pulsar and perform manual feed.
Auxiliary  control  function	Command unit setting		You can set a desired unit of control for each axis according to the  machine.
	Accel-  eration/  decel-  eration  control	Auto acceleration/  deceleration  control	This function automatically generates an acceleration/deceleration  curve for axis operation. You can select the trapezoidal curve or  the S-curve based on a tertiary function.
		Acceleration/  deceleration  time change	You can change the acceleration/deceleration time during  acceleration/deceleration.
		Acceleration/  deceleration  point switch	You can select one of three methods to connect speeds in different  operation patterns during continuous-pattern memory operation.
	Override		This function changes the speed of the axis which is currently in  positioning operation.
	Backlash Compensation		This compensates for the mechanical plays to increase the positioning  accuracy.
	M code		You can output M codes to implement interlocking with external  machines during memory operation.
	Zone setting		You can set a desired zone and assess whether the present position is  inside the zone. Up to 3 zones are settable for each axis.
	Feedback pulse counter		A feedback pulse counter input is available for each axis.  You can connect encoder pulse outputs from a Servo Drive to monitor  deviation from the command position, etc.
	Absolute encoder		You can input encoder pulses from a Servo Drive to a feedback  pulse counter to use a motor with absolute encoder.  This function supports OMRON G-series and G5-series Servomotors  with absolute encoder.
	Teaching		This function enables loading of the present position into memory  operation position data.  It supports not only the present command position, but also the  present position from the feedback pulse counter.
	Torque limit output		An output signal is available for operating the torque limit switch  input of a Servo Drive.  You can turn this output signal ON/OFF directly in the ladder  program. Also, Origin Search by holding supports automatic switching  of torque limits.
	Monitor  function	Software limits	You can set forward/reverse direction software limits of axis operation.  If the positioning target exceeds software limit, it is detectable at the  start through a command value check.
		Position or speed  error monitor	The PCU can monitor the position or speed error between the present  command position and present feedback position to generate an error  and stop the axis operation upon detection of an excessive error.
		Error between  axes monitor	It can also monitor the error between axes during linear interpolation to  generate an error and stop the axes operation upon detection of an  excessive error.
