Note: The Motor Thermal and analog position reference are NOT
brought out to these follower connectors.
The pin layout for these connectors is illustrated in the following
table.
Configuration Links Configuration links have been provided on the Encoder Buffer Unit to
let you set the Encoder Supply Voltage, Encoder Direction, and
Follower Power. The Configuration Links are a series of pins and
two-way jumpers. The required configuration is set by connecting the
pins with the two-way jumpers as specified in the following
directions.
Encoder Supply Voltage
The Encoder Buffer Unit lets you set the Encoder Supply voltage to
either +5V DC or +12V DC. This is done through the three-way link
marked LK-VOLTS . Where you place the two-way jumper determines
the supply voltage.
The Encoder Supply Voltage is set by placing the two-way jumper so
that is connects the link pins in the following sequence:
For a 12V Encoder Supply, Link 1- 2.
For a 5V Encoder Supply, Link 2 – 3
