P5.1 - Basic settings.
Motor control mode
P5.1.1 ab
Minimum value: N.A.
Options: 0 = Frequency control - Output frequency is controlled directly by the frequency reference.
1 = Speed control - Output frequency is controlled by giving a frequency reference to it with slip compensation.
2 = Open loop vector control - Similar to the standard speed control mode, higher performance slip calculation requires running a motor
identification.
3 = PM control 1 - PM motor control mode 1, used for SPM (surface mounted permanent magnet) and it also can be used for IPM.
4 = PM control 2 - PM motor control mode 2, used for IPM (internally mounted permanent magnet) and it can not be used for SPM.
Description: Selects the motor control
Current limit
P5.1.2 a
DriveNomCurrCT*1/10 A
Minimum value:
Description: This parameter determines the maximum output current allowed from the drive. The parameter value range differs from size to size.
Once the motor current hits this level, it goes into the current limiter controller and tries to limit the output current.
V/Hz optimization
P5.1.3 ab
Minimum value: N.A.
Options: 0 = Disable torque boost function.
1 = Enable torque boost function.
Description: Automatic torque boost - the voltage to the motor increases automatically, which assists the motor to produce sufficient torque to start
and run at low frequencies with high loads.
V/Hz ratio
P5.1.4 ab
N.A.
Minimum value:
Options: 0 = Linear - the voltage of the motor changes linearly with the frequency in the constant flux area from 0 Hz to the field weakening point
where the nominal voltage is supplied. A linear V/Hz ratio should be used in constant torque applications.
1 = Squared - the voltage of the motor changes following a squared curve with the frequency in the area from 0 Hz to the field
weakening point where the nominal voltage is supplied. The motor runs under magnetized below the field weakening point and
produces less torque and electromechanical noise. A squared V/Hz ratio can be used in applications where the torque demand of
the load is proportional to the square of the speed.
2 = Programmable V/Hz curve - the V/Hz curve can be programmed with three different points. These points are the 0 frequency
voltage, midpoint and weakening point. A programmable V/Hz curve can be used if the other settings do not satisfy the needs of
the application.
3 = Linear with flux optimization - the drive starts to search for the minimum motor current in order to save energy. This mode is called
Eaton's Active Energy Control which will reduce the voltage and current but still maintain the desired speed.
Description: Selects the V/Hz ratio.
0 = Linear;
1 = Squared;
2 = Programmable; or
3 = Linear + flux optimization.
Field weakening point
P5.1.5 ab
Minimum value: 8.00 Hz
Description: The field weakening point is the frequency at which the output voltage reaches the set maximum value. This value is usually determined
by the motor nameplate value.
