P-Group: SETPOINT Active: first confirm QuickComm. Yes Max: 650.00
Sets maximum motor frequency [Hz] at which motor will run irrespective of the frequency setpoint.
Dependency:
The maximal value of motor frequency P1082 is limited to pulse frequency P1800. P1082 is dependent on
the derating characteristic as followed:

When P1300 < 20 (control mode = VF or FCC modes) then max output frequency is limited to smallest of
650 Hz or ( maximum pulse frequency / 15)
Note:
The value set here is valid for both clockwise and anticlockwise rotation.
The maximum output frequency of inverter can be exceeded if one of the following is active:
