■Turning on/off the servo-on command [A]
When the servo-on command is turned off, the servo lock is released after Tb [ms], and then the servo motor coasts.
If the electromagnetic brake is enabled during servo-lock, the brake life may be shortened. Therefore, when using with the
vertical axis, set Tb to about 1.5 times of the minimum delay time where the moving part will not drop down.
