2.4.16.1 Function 1: CMP1−IN1 = CMP1−IN2
l Selection: C0680 = 1
l This function compares two signals. For instance, you can compare the actual speed and the
setpoint speed (n
act.
= n
set
).
l The exact function can be obtained from the line diagram.

Fig. 2−54 Equality of signals (CMP1−IN1 = CMP1−IN2)
Function procedure
1. Under C0682, set the window where the equality is to be effective.
2. Under C0681 you set a hysteresis if the input signals are not stable and therefore the output
oscillates.
