7.3.3.4 Analog Input Deadband
In analog control model, even when the input voltage is 0V, it is almost impossible to ensure that the
input voltage is absolute 0V due to external interferences. In some cases, it might cause the motor to
turn slowly in either direction. Therefore, it is recommended that a reasonable deadband value be set to
prevent this issue.
The analog input deadband can be configured via M Servo Suite or parameter P-56 (AD1) directly from
the drive’s control panel.
