The OEM750X produces a shutdown output that is identical
to its own internal signal. This output may be used to slave to
another drive or to monitor the OEM750X. The shutdown
output's default state is logic high. The figure represents a
typical configuration of this output. (Refer to the
ST com-
mand.)

PERATION
Closed loop moves require an external encoder to provide
position correction signals. Motor position may be adjusted to
reach the desired position. To implement the closed loop
functions, you must connect a single-ended, incremental,
optical encoder to the OEM750X. You can then use the
FS
commands, which add the functions below:
• Encoder referenced positioning
• Encoder position servoing
• Motor stall detection
• Higher accuracy homing function
