Function description
Signal that is longer than10s does not cause a reset.

Start-up monitoring time starts if f>1Hz
2
Start-up monitoring time is expired. Enabling
current path remains closed because f>V-LIMIT
1.
3
Enabling current path opens because f<V-LIMIT
1.
4
Enabling current path closes, if f<0,5Hz.
5
Start-up monitoring time starts if f>1Hz.
6
Start-up monitoring time is expired. Enabling
current path opens because f < V-LIMIT 1.
7
The setpoint speed was reached outside of the
minimum switch-off time. Enabling current path
closes.
8
The setpoint speed was reached within the min-
imum switch-off time. Enabling current path
closes after 0.5s.

1
Start-up monitoring time starts with the falling
edge of the acknowledgement signal.
2
Start-up monitoring time is expired. Enabling
current path remains closed because f>V-LIMIT
1.

Enabling current path opens because f<V-LIMIT
1.
4
Start-up monitoring time starts with the falling
edge of the acknowledgement signal.
5
Start-up monitoring time is expired. Enabling
current path opens because f < V-LIMIT 1.
6
Start-up monitoring time starts again.
7
Start-up monitoring time is expired. Enabling
current path remains closed.
8
Enabling current path closes because
V-LIMIT 1<f<V-LIMIT 2.
