Parameters (Page 349)
NOTICE
Incorrect direction of motor rotation if the parameterization is not suitable
If you are using an analog input as speed setpoint source, then for a setpoint = 0 V, noise
voltages can be superimposed on the analog input signal. After the on command, the motor
accelerates up to the minimum frequency in the direction of the random polarity of the noise
voltage. A motor rotating in the wrong direction can cause significant material damage to the
machine or system.
● Inhibit the motor direction of rotation that is not permissible.
