To operate the easYgen in this configuration correctly, the fol‐
lowing needs to be done:
The easYgen requires an external feedback, that the drive
n
system will be started. That is the precondition for the easYgen
to trigger the delayed monitoring function, which activates, after
a delay time, the speed related monitoring functions. (under‐
speed, underfrequency, undervoltage, etc.)
The easYgen requires an external feedback, that the drive
n
system will be stopped. That is the precondition for the
easYgen to deactivate the speed related monitoring functions.
This avoids upcoming alarms due the drive system is stopped.
The easYgen must be directed to switch into the active opera‐
n
tional mode or to exit this operational mode. The operational
mode proceeds with the actions according to the configured
application and transition modes.
The following section shows a practical example, to explain in
detail the described above configuration.

The external start/stop device gives an feedback to the

easYgen via discrete input [DI 02] ("09.02 Discrete input 2")
that the drive system will be started or already is started.
"Firing speed"
When simultaneously the firing speed ("02.01 Firing speed") is

reached, the equation becomes TRUE and the delayed moni‐
toring function will be triggered.
For security reasons a closed GCB ("04.06 GCB closed")
