p0309[0...n]
Rated motor efficiency / Mot eta_rated
VECTOR
Can be changed: C2
Data type: Floating Point
P-Group: Motor
Min
0.0 [%]
Description:
Sets the rated motor efficiency (rating plate).
For a parameter value of 0.0, the power factor is internally calculated and displayed in r0332.
Dependency:
This parameter is only available for NEMA motors (p0100 = 1).
Refer to: p0100, p0308, r0332
Note:
The parameter is not used for synchronous motors (p0300 = 2xx).
The parameter is automatically preset for motors from the motor list (p0301).
p0310[0...n]
Rated motor frequency / Mot f_rated
VECTOR
Can be changed: C2
Data type: Floating Point
P-Group: Motor
Min
0.00 [Hz]
Description:
Sets the rated motor frequency (rating plate).
Dependency:
The number of pole pairs (r0313) is automatically re-calculated when the parameter is changed (together with
p0311), if p0314 = 0.
Only for vector drives (refer to p0107):
The rated frequency is restricted to values between 1.00 Hz and 650.00 Hz.
Refer to: p0311, r0313, p0314
Note:
The parameter is automatically pre-assigned for induction motors from the motor list (p0301).
For synchronous motors, the parameter is not required and must therefore be pre-assigned zero. For p0310 = 0, it
is not possible to calculate the pole pair; instead, it must be entered in p0314.
p0311[0...n]
Rated motor speed / Mot n_rated
VECTOR
Can be changed: C2
Data type: Floating Point
P-Group: Motor
Min
0.0 [1/min]
Description:
Sets the rated motor speed/velocity (rating plate).
For vector drives (refer to p0107):
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 closed-loop vector control and slip compensa-
tion for V/f control.
Dependency:
The following applies for rotating motors:
If p0311 is changed and for p0314 = 0, the pole pair (r0313) is re-calculated automatically.
The following applies for linear motors:
The pole pair width is set in p0315.
Refer to: p0310, r0313, p0314
Note:
The parameter is automatically preset for motors from the motor list (p0301).
