Parameters
List of Parameters
p0309[0...n] Rated motor efficiency / Mot eta_rated
Access level: 1
Can be changed: C(1, 3)
Units group: -
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.
p0310[0...n] Rated motor frequency / Mot f_rated
Access level: 1
Can be changed: C(1, 3)
Units group: -
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.
The rated frequency is restricted to values between 1.00 Hz and 650.00 Hz.
Refer to: p0311, r0313, p0314
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Notice: If p0310 is changed during quick commissioning (p0010 = 1), the maximum speed p1082, which is also associated
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.
p0311[0...n] Rated motor speed / Mot n_rated
Access level: 1
Can be changed: C(1, 3)
Units group: -
Min
0.0 [rpm]
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 U/f
control.
Dependency: If p0311 is changed and for p0314 = 0, the pole pair (r0313) is re-calculated automatically.
Refer to: p0310, r0313, p0314
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Notice: If p0311 is changed during quick commissioning (p0010 = 1), the maximum speed p1082, which is also associated
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.
