Keba ServoOne User Manual

In addition to the process controller status word, bit 8 of the device status word,
P702[0] - MON_State, will be set when the setpoint is reached. P2679[0] - CON_
PRC_RefReached can be used to configure the “Reference value attained” window
for this purpose. Bit 8 will be set to TRUE if the process controller’s deviation is less
than 50% of the configured “Reference value attained” window.
7.10.2.2Referencevalues
The process control circuit setpoint can be selected via pre-defined setpoint sources.
P2683[0] - CON_PRC_REFSEL can be used to select these setpoint sources.

NOTE
If the target value source is selected, the respective input must also have
a function assigned to it.

Once the setpoint source is selected, the process controller setpoint can be set with
P2666[0] - CON_PRC_REFVAL. This setpoint can then be scaled further with
P2667[0] - CON_PRC_REFSCALE in order, for example, to incorporate decimal
places and/or unit conversions.
7.10.2.3Actualvalues
The process control circuit actual value can be selected via a number of pre-defined
actual value sources. P2668[0] - CON_PRC_ACTSEL can be used to select these
actual value sources.
