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

4.1.1.3 Halls-only feedback devices
Feedback devices using only Hall sensors may be connected to the MicroFlex
e
100. However,
since there are no encoder connections, the MicroFlex
e
100 will not be able to perform smooth
speed control or accurate positioning control.
