4.2 Drive Enable
Drive enable is used to enable all your drives. When activated, the drive enable relay connects the external enable
(EXT) to the servo enable (SOV) terminals on TB2. The signal SOV runs to each axis control mod jack (See Table 2
Axis Control Mod Jack Pinouts). You can jumper EXT to 5V, 24V, GND, or any other DC voltage for different enable
signals depending on what your servo drives require. Again, remember that the emergency stop terminals must be
connected for anything to enable.
