258 Servo Drive
IXT Servo Parameter
ACTION:
Sets or returns the Excessive Duty Cycle Shutdown time in seconds.
PROGRAM SYNTAX:
IXT(axis) = expression
IXT(axis, … , axis) =expression, … , expression
IXT = expression, … , expression
IXT(axis) - used in an expression
REMARKS:
The axis specifies the number of the axis (1-8).
The expression specifies the time the servo peak current can be main-
tained. The time value is in seconds and the default value for each axis is
3 seconds. Setting the expression equal to 0 will disable the Excessive
Duty Cycle Shutdown check.
Caution: Disabling the Excess Duty Cycle or setting the time too
large may result in damage to the servo drive and/or motor if the
duty cycle of the servo amplifier is exceeded.
The
IXT(axis)=expression
program command should precede the
WNDGS(axis)=1
command.
The default value for IXT is set each time a project is loaded or executed.
Thus, adding an IXT basic command to a task is the only way to change
the default value.
If an Excessive Duty Cycle Shutdown occurs the user task will error trap
and all motors in the task will be stopped. The servo axis with the exces-
sive duty cycle will be disabled resulting in the motor shaft spinning
freely unless it is held by and external brake. Error code 26,
IXT Servo
Error
will be generated for this axis.
EXAMPLES:
IXT(1) = 5
‘ sets the Peak Current time for axis 1 to 5 secs.
WNDGS(1)=1
‘ enable the servo drive on axis 1.
IXT(1,3) = 5,6
‘ sets the Peak Current time for axis 1 to 5 secs and axis 3 to 6 secs.
WNDGS(1,3)=1,1
‘ enable the servo drive on axis 1 and axis 3.
IXT = 5, ,6
‘ sets the Peak Current time for axis 1 to 5 secs and axis 3 to 6 secs.
WNDGS(1,3)=1,1
‘ enable the servo drive on axis 1 and axis 3.
time = IXT(1)
‘ return the Peak Current time setting of axis 1
