PID actual value
The functions PID-reference value and PID-actual
value can be addressed as analog signals or via
fieldbus. A control error is calculated from these
signals. The control error is used as the input
variable for the PID controller. The reference value
set in G132 is used when D34 is parameterized to
0:analog signals.

PID upper limit
reached
A high level means that the PID controller has reached the maximum
permissible value (can be set with G08) on the output.

PID lower limit
reached
A high level means that the PID controller has reached the minimum
permissible value (can be set with G09) on the output.

Description
When the drive follows the master reference value (see chap. 1.2.6), the actual speed is
measured. This measured value is used as n-actual. When synchronous operation is
concluded (i.e., the master reference value is disabled) the slave can be run with its last
valid speed when the reference value path with D30=6:n-actual is used.
