7.4.3.4 Analog Deadband
In analog control mode, even when the input voltage is 0V, it is impossible to ensure that the input voltage
is absolutely zero due to external interference. In some cases, it might case motor turn slowly in either
direction. Therefore, it is recommended that a reasonable deadband value be set up to prevent this issue.
It can be set by M Servo Suite or P-57 (AD2) directly from the drive’s control panel.
