Type
Mathematical function
Syntax
ATAN(expression)
Description
The
ATAN
function returns the arc-tangent of the argument.
expression
can
have any value. The result is in radians and is between -PI/2 and PI/2.
Arguments
•
expression
Any valid BASIC expression.
Example
>> PRINT ATAN(1)
0.7854

Type
Mathematical function
Syntax
ATAN2(expression1, expression2)
Description
The
ATAN2
function returns the arc-tangent of the non-zero complex number
(expression1, expression2)
, which is equivalent to the angle between a
point with coordinate
(expression1, expression2)
and the x-axis. If
expression2 >= 0
, the result is equal to the value of
ATAN(expression1 /
expression2)
. The result in radians will be between -PI and PI.
Arguments
•
expression1
Any valid BASIC expression.
•
expression2
Any valid BASIC expression.
Example
>> PRINT ATAN2(0,1)
0.0000

Type
Axis parameter
Syntax
ATYPE = value
Description
The
ATYPE
axis parameter indicates the axis type for the axis. The valid val-
ues depend on TJ1 module the Servo Drive controlling the axis is connected
to. See the table below.

The
ATYPE
parameters are set by the system at start-up. For axes controlled
by the Servo Drives connected to the system via MECHATROLINK-II bus, the
default
ATYPE
value is 40 (MECHATROLINK-II Position). For axes controlled
by the Servo Drives connected to the system via the TJ1-FL02, the default
ATYPE
value is 44 (Flexible Axis Servo).
