7.4.8 Calibration of function U - RI (R133 - R134)
This adaptation is necessary even when operating with a tachogenerator to ensure tacho safety:
speed signals from "U - RI" and from the tacho are compared constantly and must be of the
same order of magnitude.
EMF per 1000 rpm : The electromotive force constant KE indicates the voltage measured on the
armature for an off-load speed of 1000 rpm, at 25°C. Under load, for agiven
voltage, motor speed will be:
I = current between terminals in Amps
R = armature resistance in Ohms
U = voltage across terminals in Volts
K
E
= EMF constant in Volts per 1000 rpm
N = U - (RI) x 1000
