Comparators
Comparators are used for comparing continuous variables
(output frequency, output current, analog input, and so on)
to xed preset values.

Combine up to 3 boolean inputs (TRUE/FALSE inputs) from
timers, comparators, digital inputs, status bits, and events
using the logical operators AND, OR, and NOT.

3.4 Dynamic Braking Overview
Dynamic braking slows the motor using 1 of the following
methods:
•
AC brake
The brake energy is distributed in the motor by
changing the loss conditions in the motor
(parameter 2-10 Brake Function = [2]). The AC
brake function cannot be used in applications
with high cycling frequency since this situation
overheats the motor.
•
DC brake
An overmodulated DC current added to the AC
current works as an eddy current brake
(parameter 2-02 DC Braking Time ≠ 0 s).
