A.6 Slew Rate Control
Usually, the output of an analog output module changes
instantaneously. That is, when the module receives an
output command, its output changes to the specified value
immediately. However, it may require that the output
change to the specified value gradually in some
applications. The slew rate control is to adjust the output
change rate.
The I-7021, I-7021P, I-7022, M-7022, I-7024, I-7024R,
M-7024, M-7024L, M-7024R, M-7024U and M-7028
modules support programmable slew rate control. When
an analog output command is received, the analog output
will change to the new value in the specified slew rate
automatically. The I-7021, I-7021P, I-7022, M-7022,
I-7024, I-7024R, M-7024, M-7024L, M-7024R, M-7024U
and M-7028 modules update the analog output every 10
ms. The analog output is updated smoothly until it
reaches the specified output value.
