Connecting to the Analog Input on the IN/OUT 2 Connector
The analog input on the IN/OUT 2 connector can be used by “Feed to Sensor” commands
and other input functions when operating the drive in “Host” mode. The analog input can also
be read back to the “Host” using the “IA3” immediate command. Readings are in Volts. See
“BLu Servo Host Command Reference” for more information.
+5 volt DC is provided for powering potentiometers. A 1000 to 10000 ohm potentiometer is
recommended and should be connected as shown below.
A 0 to 5 volt analog signal may also be used. Usually this signal comes from a PLC, a PC
with data acquisition card or a motion controller. Connections are shown below.
The +5V terminal is an output. Do not connect it to a power supply.
