Connecting Single-Ended Hall Sensors
Single-ended Hall sensors may be connected to the servo drive as shown below. The output
of the Hall sensors must be able to “sink” 10 mA of current in order to properly drive the hall
sensor inputs. Typically open collector outputs are best suited to driving the hall sensor inputs.
Connecting a Single-Ended Encoder
Single-ended encoders may be connected to the servo drive as shown below. In some cases
this may cause loss of encoder data. Typically, a single ended encoder’s source impedance
is high and cannot drive a terminated transmission line. Because of this, single-ended signals
may be more susceptible to noise.
