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.
	Multi- axis control	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.
	Memory operation	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.
