SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Sets the rated motor frequency (rating plate).
Dependency: The number of pole pairs (r0313) is automatically recalculated when the parameter is changed (together with
p0311), if p0314 = 0.
The rated frequency is restricted to values between 1.00 Hz and 650.00 Hz.
Refer to: p0311, r0313, p0314
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Notice: If p0310 is changed during quick commissioning (p0010 = 1), then the maximum speed p1082, which is also asso-
ciated with quick commissioning, is pre-assigned accordingly.
Note: Once the Control Unit has been booted up for the first time or if the factory settings have been defined accordingly,
the parameter is defined in accordance with the power unit.
Description: Sets the rated motor speed (rating plate).
For p0311 = 0, the rated motor slip of induction motors is internally calculated and displayed in r0330.
It is especially important to correctly enter the rated motor speed for vector control and slip compensation for V/f
control.
Dependency: If p0311 is changed and for p0314 = 0, the pole pair (r0313) is recalculated automatically.
Refer to: p0310, r0313, p0314
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Notice: If p0311 is changed during quick commissioning (p0010 = 1), then the maximum speed p1082, which is also asso-
ciated with quick commissioning, is pre-assigned accordingly.
Note: Once the Control Unit has been booted up for the first time or if the factory settings have been defined accordingly,
the parameter is defined in accordance with the power unit.
Description: Displays the number of motor pole pairs. The value is used for internal calculations.
Values:
r0313 = 1: 2-pole motor
r0313 = 2: 4-pole motor
etc.
Dependency: For p0314 > 0, the entered value is displayed in r0313.
For p0314 = 0, the pole pair number (r0313) is automatically calculated from the rated power (p0307), rated fre-
quency (p0310) and rated speed (p0311).
Refer to: p0307, p0310, p0311, p0314
Note: For the automatic calculation, the pole pair number is set to the value of 2 if the rated speed or the rated frequency
is zero.
