8.5.4 Limit (Configuration
Limit)
The T400 series offers 2 independent limits
Limit 1 and 2.
Status
Limits are selected here. If the limit is deactivated, the other values such as set points and mode have no
further effect.
Mode
In Normal Mode the limit is active as soon as the High set point is exceeded. In Inverse Mode the limit is active
from the start (zero speed) and deactivates when the set point is reached (Fail Safe operation)

As the speed increases, the limit switches when the High set point is reached and remains in that condition
until the speed reduces past the Low set point.
8.5.5 Relay parameter and selection of Parameter set
(Configuration
Relay control)
Parameter set A / B selection
The parameter set B may be activated via the binary input <Binary input B1>.
If parameter set B is to be deactivated, this setting should be none (always control A)
Delay time when switching B -> A
This value corresponds to the time needed for switching from parameter set B to parameter set A after
changing the binary input accordingly.
Relay assignment with control A
Defines the relay behavior in parameter set A.
Relay assignment with control B
Defines the relay behavior in parameter set B.
Relay
Defines the source information for relay switching.

Acknowledge
Acknowledge establishes if and under what conditions the relay status is held. A relay that is held no longer
reacts to the assigned signal and can only be reset via the binary input.
