Dead band
With the control enabled, electromagnetic interference on the signal cable can cause the motor
to slowly rotate in one direction in spite of a speed setpoint = 0.

The dead band acts on the zero crossover of
the analog input characteristic. Internally, the
inverter sets its speed setpoint = 0, even if
the signal at the analog input terminals is
slightly positive or negative. This prevents
the inverter from rotating the motor at a
speed setpoint = 0.
