Example
The expressions evaluated can be as complex as you like provided they fol-
low BASIC syntax, for example:
WAIT UNTIL DPOS AXIS(2) <= 0 OR IN(1) = ON
The above line would wait until the demand position of axis 2 is less than or
equal to 0 or input 1 is on.

Type
System parameter
Syntax
WDOG
Description
The
WDOG
parameter contains the software switch which enables the Servo
Drive using the
RUN
(Servo on) input signal. The enabled Servo Drive will
control the servo motor depending on the speed and torque reference values.
WDOG
can be turned on and off under program control, on Command Line
Terminal and the Trajexia Studio control button.
The Servo Drive will automatically be disabled when a
MOTION_ERROR
occurs. A motion error occurs when the
AXISSTATUS
state for one of the
axes matches the
ERRORMASK
setting. In this case the software switch
(
WDOG
) will be turned off, the
MOTION_ERROR
parameter will have value
different than 0 and the
ERROR_AXIS
parameter will contain the number of
the first axis to have the error.
Note: The
WDOG
parameter can be executed automatically by Trajexia Stu-
dio when the
Drives Enabled
check box is clicked on the control panel.

Type
Program control command
Syntax
WHILE condition
commands
WEND
Description
The
WHILE ... WEND
structure allows the program segment between the
WHILE
and the
WEND
statement to be repeated a number of times until the
condition becomes
FALSE
. In that case program execution will continue after
WEND
.
Note:
WHILE ... WEND
loops can be nested without limit.
Arguments
•
condition
Any valid logical BASIC expression.
Example
WHILE IN(12) = OFF
MOVE(200)
WAIT IDLE
OP(10,OFF)
MOVE(-200)
WAIT IDLE
OP(10,ON)
WEND

Type
Mathematical operation
Syntax
expression1 XOR expression2
Description
The
XOR
(eXclusive OR) operator performs the logical
XOR
function between
corresponding bits of the integer parts of two valid BASIC expressions.
The logical
XOR
function between two bits is defined as in the table below.
