107.43 Nominal torque
Display of nominal torque (at motor nominal temperature, i.e. motor warm); calculated
from nominal output and nominal speed.
107.44 Kt factor
Display motor torque constant in Nm/A.
The connection between torque-generating current and motor torque at the nominal point
(i.e. magnetic flux = 100% and at the nominal temperature "warm" motor).
The Kt factor is calculated from the nominal torque M
nom
(Z107.43–) and nominal torque
current l
sq-nom
(Z19.10–) of the motor.
The exact correlation between the torque current and the torque is shown in the torque
monitoring (
ZFig. 133– on page 505).
107.67 Pole pitch
Pole pitch for linear measuring systems.
107.68 Load inertia
Load inertia can be used for the calculation of the parameters of the speed controller from
the data sheet in ProDrive. The parameter is not part of the electronic type plate and must
be entered manually.
107.72 Continuous current limit curve
The supporting points of the continuous current limit characteristic (motor duty type: S1)
are entered in 107.72[0] to 107.72[10]. 107.72[0] should be equal to the standstill current
value (
Z107.10–), while in other elements the current values must be entered in a fixed
distance of a maximum speed mechanical (Z107.26–) divided by 10.
The selection and the entering of the values can be made manually or by an available
supporting point set in the Baumüller motor data base. Generally, the supporting points
107.72[0] to 107.72[10] are assigned zero.
The parameter can be changed in the inhibited state, only.
