Defining TAG initial values
The initial_value format follows the C-language initialization
syntax, except that you use square brackets instead of curly brackets.
The following table shows some examples of entering initial values.
The initial value for a string value identifies the number of characters
in the string and the text string. The format for a string TAG is:
< tag_name > : STRING := [< number >, ‘ string_text $00 ... $00’];
Where:
BrakeEngageDelayTime
Specify the amount of time that the drive maintains torque when the servo axis is disabled
and the drive decelerates to a minimum speed (0-6.5535).
Specify:
BrakeEngageDelayTime := value
BrakeReleaseDelayTime
Specify amount of time that the drive ignores command values from the controller when
the servo axis is enabled and the drive activates the torque (0-6.5535).
Specify:
BrakeReleaseDelayTime := value
PowerSupplyID
Specify the power supply ID (any positive number).
Specify:
PowerSupplyID := value
BusRegulatorID
Specify the bus regulator ID (any positive number).
Specify:
BusRegulatorID := value
Attribute: Description:
If the tag is: Enter:
single, atomic value [
Value ]
structure with three members [
Value1 , Value2 , Value3 ]
structure with a nested structure [
Value1 , [ Value2 , Value3 ], Value4 ]
structure with a nested array [
Value1 , [ ArrayValue1 , ArrayValue2 ], Value3 ]
Item: Identifies:
tag_name
name of the string tag
STRING
the STRING data type
number
number of characters in the string
string_text
text of the string
$00
the string is padded with $00 to fill its maximum of
82 characters
Each $00 equals one character not used in the string.
The entire text string, including the $00 characters, is
enclosed in single quotation marks.
