Operation 3-5
The default setting is As Master.
Follower Power
The Follower Power configuration link sets the follower output to
either unpowered or powered. There is one Configuration Link for
each follower channel, marked LK-5V-F1 etc. These are three-way
links with two-way jumpers. In the powered state, the follower
supplies +5V output power.
To set the Follower output to unpowered, link 1- 2 with the two-way
jumper.
To set the Follower output to powered, Link 2 - 3 with the two-way
jumper.
The following diagram shows the layout of the links that select
encoder supply voltage. These are located to the left of the Follower
Output that they effect and are numbered accordingly.
The following diagram shows the text indicating the selection options
for the Follower Outputs. It is located in one location near the top of
the board.
WARNING
!
A feedback loop must not be closed via the
Encoder Buffer Unit. Use of this Buffer in the
feedback path of a position controller disables any
"encoder loss" detection function which can cause a
runaway condition.
Failure to observe these warnings will cause
unexpected and/or uncontrolled movement of
peripheral equipment. This may cause damage to the
equipment and to your health and safety.
