Jog Speed 1
Jog Speed 2
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.

Shutdown 1
Shutdown 2
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.
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.

Retract Jog 1
Retract Jog 2
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.
