4-4 Feedback MN1942
4.1.1.2 Encoders without Halls
Incremental encoders without Hall feedback connections may be connected to the
MicroFlex e100. However, if Hall connections are not present, it will be necessary for the
MicroFlex e100 to perform an automatic phase search sequence each time it is powered. This
willc ause motor movement of up to 1 turn on rotary motors, or one pole-pitch on linear motor s.

4.1.1.3 Halls-only feedback devices
Feedback devices using only Hall sensors may be c onnected to the MicroFlex e100. However,
since there are no encoder connections, the MicroFlex e100 will not be able to perform smooth
speedc ontrol or accurate positioning control.

Note: If the Hall inputs are used as single ended inputs, leave the Hall U-, Hall V- and
HallW -pins unconnected; do not connect them to ground.
