If you set P1.9=drive selection to value 1=travel on the step 4, autotune the inverter. After autotuning,
go to step 8. Steps 6 and 7 are done only with compact brake motors.
AUTOTUNING
5.1 Ensure that parameters P3.1 (Motor Nominal Voltage), P3.2 (Motor Nominal Frequency), P3.4
(Motor Nominal Current), P3.5 (Motor Nominal Flux Current), P3.6 (Motor Cos Phi) are equal to
the motor rating plate values If motor no-load current is not known, set P3.5 (Motor Nominal Flux
Current) equal to zero. Auto-tuning then uses motor cos phi for calculations instead of no-load
current.
5.2 Set parameter P3.7 (Autotuning) = 1. Auto-tuning will start right after the parameter change. RUN
indicator on the display turns on (and STOP indicator turns off). Autotuning will take about 5
seconds.
5.3 After auto-tuning, parameter P3.7 (Autotuning) = 3, successfully done.

(only with compact brake motors)Set motor control parameters.
• P3.2=Motor nominal frequency in percent of motor nominal voltage.
• P4.1=zero frequency voltage in percent of motor nominal voltage.
• P4.2=U/f mid voltage in percent of motor nominal voltage.
• P4.3=U/f mid frequency in Hz.
• P4.4=Rs voltage drop in percent of motor nominal voltage.
