6-22 Keypad Programming MN1854
Value: N/A
Units: N/A
Range: 0.0001 – 214748.3645
The SQ command calculates the square root of a number and returns the result in a user defined variable.
The n parameter in the syntax can be a number or a variable parameter, however, the second parameter
must be a previously defined variable for which the square root result is stored. If the second parameter is
not a defined variable, you will get a Bad Variable Name error. Following mathematical convention, SQ will
produce an Invalid Parameter error for negative “r” values. The return value is accurate to the 0.01 place.
Example: This program calculates the square root of 27.96 and stores the value in the user defined
variable (SQRESULT).
(SQRESULT)=0 SQ27.96
,(SQRESULT) The returned value in (SQRESULT) is 5.28.

Range: 0–8 inputs
ST stops move execution upon activating the input specified by n.
ST0 disables (turns off) the STn command.
ST#1 stops the move on axis #1. (Allows program command conditional program termination). ST#1,#2
stops moves on both axes. After ST is executed, the specified input is monitored during every “move
profile”. If the input is activated, the current “move in progress” is terminated, stopping all motion until the
input is deactivated or an ST0 is processed. LinStep+ will process and calculate commands, but will wait at
the next GO command until the ST input changes.
The motor is stopped at the deceleration rate specified in the Stop Decel Rate parameter. Once issued, Stop
on Input remains active until it is turned off by the ST0 command, a reset is issued, or power is cycled.
Example:
ST1
AC1 DE1 VE25 DA6 GO VE50 DA0 GO EN
Move to absolute position 6 units. If input 1 is activated while moving, Stop Motion. When the input is
deactivated, immediately execute the next move profile which is to move to the absolute zero position. If
input 1 is not activated while moving, the motor would complete its 6 unit move before executing the move
back to absolute zero.
ST
Stop Move on Input
syntax – STn (or ST#n)

Value: N/A
Units: seconds
Range: r=0.01 – 99999.99
Delay r seconds before executing the next command.
Example:
VE50 DI4 GO OT11 TD.5
OT00
Move 4 units, turn outputs 1 and 2 on, delay .5 seconds, and turn outputs 1 and 2 off.
TD
Time Delay
syntax – TDr
