SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Sets maximum motor frequency [Hz] at which motor will run irrespective of the frequency setpoint.
The value set here is valid for both clockwise and anticlockwise rotation. Futhermore, the monitoring function |f_act|
>= P1082 (r0052 Bit10, see example below) is affected by this parameter.
Example:
Dependency:
The maximum value of P1082 also depends on the nominal frequency: Max. P1082 = min(15*P0310, 650 Hz).
As consequence P1082 can be affected if P0310 is changed to a smaller value.
The maximum frequency and the pulse frequency depending on each other. The maximum frequency affects the
pulse frequency according to the following table.
Example:
If P1082 is set to 350 Hz a pulse frequency from at least 6 kHz is necessary. If P1800 is smaller than 6 kHz the
parameter is changed P1800 = 6 kHz.
The maximum output frequency of inverter can be exceeded if one of the following is active:
The resultant value is displayed in r1084 (resultant maximum frequency).
