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