4.13.4 14-3* Current Limit Control
The frequency converter features an integral current limit
controller, which is activated when the motor current, and
thus the torque, is higher than the torque limits set in
parameter 4-16 Torque Limit Motor Mode and
parameter 4-17 Torque Limit Generator Mode.
When the current limit is reached during motor operation
or regenerative operation, the frequency converter tries to
reduce torque below the preset torque limits as quickly as
possible without losing control of the motor.

Function:
[0 - Enter the current limit trip delay in seconds. When
the output current reaches the current limit
(parameter 4-18 Current Limit), a warning is
triggered. When the current limit warning has
been continuously present for the period specified
in this parameter, the frequency converter trips. To
run continuously in current limit without tripping,
set the parameter to 60 s=Off. Thermal monitoring
of the frequency converter remains active.
Function:
[0 - Enter the torque limit trip delay in seconds. When
the output torque reaches the torque limits
(parameter 4-16 Torque Limit Motor Mode and
parameter 4-17 Torque Limit Generator Mode), a
warning is triggered. When the torque limit
warning has been continuously present for the
period specified in this parameter, the frequency
converter trips. Disable the trip delay by setting
the parameter to 60 s=Off. Thermal monitoring of
the frequency converter remains active.
Function:
Select how the frequency converter reacts when
an overvoltage or grounding fault occurs.
Disables the protection filters and trips at the first
fault.
