Description / Notes
The Overpower and Underpower values are adjusted in percentage
of the nominal motor power (P404).
P660 sets the immediate Underpower level at which the motor
can operate during the time adjusted in P661. After this time has
elapsed the Soft-Starter is disabled indicating Underpower fault.
This function can be used in applications with hydraulic pumps that
cannot operate without load.
P662 sets the immediate Overpower level at which the motor can
operate during the time adjusted in P663. After this time has elapsed
the Soft-Starter is disabled indicating Overpower fault.
For programming examples see the item 7.2.2.
NOTE!
These functions work only with full voltage, after the motor has
been started.
