3.13.3 14-3* Current Limit Control
The adjustable frequency drive 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
4-16 Torque Limit Motor Mode and 4-17 Torque Limit
Generator Mode.
When the current limit is reached during motor operation
or regenerative operation, the adjustable frequency drive
will try to reduce torque below the preset torque limits as
quickly as possible without losing control of the motor.
While the current control is active, the adjustable
frequency drive can only be stopped by setting a digital
input to [2] Coast inverse or [3] Coast and reset inv. Any
signal on terminals 18 to 33 will not be active until the
adjustable frequency drive is no longer near the current
limit.
By using a digital input set to [2] Coast inverse or [3] Coast
and reset inv., the motor does not use the ramp-down
time, since the adjustable frequency drive is coasted.
3-88
Function:
Enter the torque limit trip delay in seconds.
When the output torque reaches the torque
limits (4-16 Torque Limit Motor Mode and
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 adjustable
frequency drive trips. Disable the trip delay by
setting the parameter to 60 s = OFF. Thermal
adjustable frequency drive monitoring will still
remain active.
Function:
[0 - 35 s] When the adjustable frequency drive
detects an overvoltage in the set time,
tripping will be affected after the set
time.

Parameters for adjusting the energy optimization level in
both variable torque (VT) and automatic energy optimi-

Function:
[0 - 500 %] Enter the proportional gain value for the
current limit controller. Selection of a high
value makes the controller react faster. Too
high a setting leads to controller
instability.
