2 PROGRAMMING OF THE MOTOR PARAMETERS
The motor parameters are set by switches S4 and S5 according to the following table. Only the most common motor
types are shown in the table. Settings for other motors can be defined when motor nominal frequency, voltage, current
and the IR-rate are known.

3.6 Defining the motor parameters
3.6.1 Motor nominal voltage and frequency
Motor nominal voltage and frequency are selected by switches S4-1 and S4-2 according to the following table:

3.6.2 IR-compensation
By the IR-compensation the effect of the stator resistance at low frequencies is compensated by increasing the U/f-ratio.
Typically the necessary amount of compensation (added voltage) is higher for small motors. The IR-compensation is set
by switches S4-3 and S4-4. Estimation of the correct setting of IR-compensation is made by calculating the IR-rate of the
motor.
