Char	Keypad Display	Input Character Description
J	Jog Speed	Jog Speed – When a jog input is activated, the control checks the state of this
		input to determine the jog speed. If the input is OFF, the system will jog at the
		Jog Low speed. If the input is ON it will jog at the Jog High speed. If the input
		is not configured the jog inputs will jog at the Jog Low speed.
		This input works along with the Extend Jog and Retract Jog.
K	Kill	Kill Motion – Causes the control to abruptly stop commanding further motion
		and terminates program execution. No deceleration ramp is used.
		Caution: instantaneous deceleration could cause damage to mechanics. The
		Stop input provides a more controlled halt.
M	Shutdown 1	Motor Shutdown – May be activated when the control is not running a
		program and the motor is idle. Selecting shutdown (M, m) will disconnect
		power to the motor, which removes current (torque) and allows the motor to
		spin freely.
N	Analog Input	Analog – Analog input is provided with the LXOPTO44 and LXOPTO88
		options. Analog input configuration is limited to inputs 1–6 only. Analog input
		values (AIx – the built–in variable) are updated every 16ms.
P	Pause/Continue	Pause/Continue – When this input is grounded, program execution is
		stopped. Moves are not interrupted when the Pause input goes active.
		Command execution will pause at the end of the move, and continue when
		the input goes high. See the ST and RG commands for interrupting moves in
		progress.
R	Retract Jog 1	Retract Jog – When activated, the motor will Jog in the Retract (–) direction.
		When the input is released, motion stops at the Jog Accel rate. If an End of
		Travel limit is hit while jogging, the motor will stop at the Stop Rate. (see
		Edit–Setup–Misc.) Before the motor can be removed from the limit, a Stop or
		Kill input must be activated to clear the fault generated by the End of Limit
		switch. Serial commands S or K will also clear the fault.
		The velocity is determined by the Jog Speed (J) input and the Jog Low and
		Jog High setup parameters. When the input is off, the speed is low. If no input
		is configured for Jog Speed, the motor will jog at the Jog Low setting.
S	Stop	Stop – When activated, any program execution or functional operation is
		immediately stopped. This includes any motion, time delays, loops, and
		faults. Moves will decelerate at the stop deceleration rate. New programs will
		not execute until the stop input goes inactive.
		See the SCAN setup parameter for more information on stopping program
		execution. See the ST command for more information on stopping moves
		without halting command execution.
U	Unassigned	Unassigned – An Unassigned input acts like a programmable input, and can
		be used in IF and WT statements just like any of the dedicated function
		inputs.
V	Data Valid	Data Valid – When configured, it determines if the Binary/BCD program select
		inputs are processed or ignored. If the input is active, program select inputs
		are processed, otherwise they are ignored. This allows applications to be
		wired in a pseudo–bus architecture fashion with each unit sharing the same
		program select lines, and the data valid inputs determining which units should
		listen. Configuring this output can greatly reduce panel wiring. In the example
		shown in Figure 5-1, using the Data Valid input reduced the number of wires
		by one–half.
W	Warm Boot	Warm Boot (System Reset) – Clears the RAM Buffer, and resets the LinStep+
		to its power–up state. Programs and setup parameters are not erased. This is
		typically used to restart the system when a fault condition occurs. The
		power–up program, if defined, will start.
