Note
In order that a stationary motor – after all of the enable signals have been switched on, can
operate at the minimum
speed/minimum velocity once all of the enable signals are available, the direction must be
entered using one of the
following options:
- direction input via small setpoint.
- direction input by inhibiting the negative or positive direction (p1110, p1111).
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=0V, 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 signicant material damage to the
machine or system.
• Inhibit the motor direction of rotation that is not permissible.
