Function
(1) The angle is calculated from the TAN (tangent) value specified by
stored into the device specified by
(2) The angle (operation result) stored at
For more information on the conversion between radian and angle data, see description of
RADD and DEGD instructions.
(3) When the operation results in -0 or an underflow, the result is processed as 0.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The value of the specified device is not in the following range:
0,2
• The value of the designated device is
