Figure8-5 Deadband of the analog input
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 deadband acts on the zero crossover of the analog input characteristic. Internally, the
converter sets its speed setpoint = 0, even if the signal at the analog input terminals is slightly
positive or negative. This prevents the converter from rotating the motor when the speed
setpoint=0.
