Response to current limit violation
You use this device parameter to specify how the motor starter is to behave in the event of
the current limits being violated:
● Warning
● Trip
Upper/lower current limit
You can enter an upper and/or lower current limit.
Example:
● "Viscosity of mixed mass is too high", that is, the upper current limit has been overshot.
● "No load because drive belt is broken", that is, the lower current limit has been violated.
Note
The current limits are not activated until the class time expires, e.g. after 10 seconds for
class 10 (start override).
If the current limits are exceeded or undershot, the motor starter responds by either
switching off or issuing a warning.
Note
The current limits can also be deactivated.
Blocking time
The blocking time is the time a block can be present before the motor shuts down. If the
blocking time expires and the system is still stalled, the motor starter is switched off.
Blocking current monitoring
The blocking current specifies how much current is consumed by the motor (at rated voltage)
when the axis is blocked.
If the motor current exceeds the parameterized value for the blocking current, the motor
starter detects the block. Blocking time monitoring is activated as of the point at which the
blocking current is exceeded. If the blocking current flows for longer than the parameterized
blocking time, the motor starter automatically generates a trip command.
