wo Wire Systems transmit and receive on the same pair of wires, which can lead to trouble. The

host must not only disable its transmitter before it can receive data, it must do so quickly, before a

drive begins to answer a query. Fortunately, the BLu servo drives include an “transmit delay”

parameter that can be adjusted to compensate for a host that is slow to disable its transmitter. This

adjustment can be made over the network using the TD command, or it can be set using the Quick

Tuner software. It is not necessary to set the transmit delay in a four wire system.
