controller will not re-enable the drive.
• The Active output will be TRUE if the servo axis is under control of
MC_Power. If the Enable input bit is FALSE, the Active output indicates
that the MC_Power is controlling the disabled state of the axis. If the
Enable input bit is TRUE and the Status and Active bits are TRUE,
MC_Power is controlling the enabled state of the axis.
• An example of recommended servo enable procedure is shown in the
MPiec Programming Best Practices Guideline . (section 7.5)
