2 Parameters
2.2 List of parameters
p0311[0...n] Rated motor speed / Mot n_rated
Access level: 1
Can be changed: C(1, 3)
Unit 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
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
If p0311 is changed during quick commissioning (p0010 = 1), the maximum speed p1082, which is also associated
with quick commissioning, is pre-assigned accordingly. The pre-assignment has been completed if the status display
r3996 returns to zero.
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.
p0312[0...n] Rated motor torque / Mot M_rated
Access level: 3
Can be changed: C(3)
Unit group: -
Min
0.00 [Nm]
Description: Sets the rated motor torque (rating plate).
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
r0313[0...n] Motor pole pair number, actual (or calculated) / Mot PolePairNo act
Access level: 3
Can be changed: -
Unit group: -
Min
-
Description: Displays the number of motor pole pairs. The value is used for internal calculations.
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
frequency (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.
