14-27 Action At Inverter Fault
Option:
84
Function:
Enter the time interval from trip to start of the
automatic reset function. This parameter is
active when parameter 14-20 Reset Mode is set
to [1]–[13] Automatic reset.
Function:
Specify normal operation, perform tests, or
initialize all parameters except for
parameter 15-03 Power Up's,
parameter 15-04 Over Temp's, and
parameter 15-05 Over Volt's. This function is
only active when the power is cycled to the
frequency converter.
Normal operation with motor selected.
Reset all parameter values to default settings,
except for parameter 15-03 Power Up's,
parameter 15-04 Over Temp's, and
parameter 15-05 Over Volt's. The frequency
converter resets during the next power-up.
Function:
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:
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.

Function:
For internal use only.
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.
Function:
[0.002 - 2 s] Control the current limit control
integration time. Setting it to a lower
value makes it react faster. A setting too
low leads to control instability.
Function:
[1 - 100 ms] Set a time constant for the current limit
controller low-pass filter.
Function:

This parameter cannot be adjusted while
the motor is running.
NOTICE
This parameter is not active when
parameter 1-10 Motor Construction is set to
options that enable PM motor mode.
Enter the level of motor magnetization at low
speed. Selection of a low value reduces energy
loss in the motor, but also reduces load
capability.
