4.14.7 14-6* Auto Derate
This parameter group contains parameters for derating the drive if there is high temperature.
Parameter 14-60 Function at Over Temperature
Table 514: Parameter 14-60 Function at Over Temperature
14-60 Function at Over Temperature
Default Value: [0] Trip
Parameter Type: Option
Setup: All set-ups
Conversion Index: -
Data Type: Uint8
Change during operation: True
If either heat sink or control card temperature exceeds a factory-programmed temperature limit, a warning is activated. If the tem-
perature increases further, select whether the drive should trip (trip lock) or derate the output current.
Option Name
Description
[0]*
Trip
The drive trips (trip lock) and generates an alarm. Cycle power to reset the alarm. The motor restarts when the
heat sink temperature has dropped below the alarm limit.
[1]
Derate If the critical temperature is exceeded, the output current is reduced until the allowable temperature has
been reached.
No trip at inverter overload
In some systems, the drive has not been sized properly to yield the current needed in all points of the operational flow-head charac-
teristic. At these points, the motor needs a current higher than the rated current of the drive. The drive can yield 110% of the rated
current continuously for 60 s. If still overloaded, the drive normally trips (causing the motor to stop by coasting) and issues an alarm.
