Compatible Optional Feedback Devices and Spindle Feedback
This section discusses optional feedback devices that are compatible with
the 9/440. The 9/440HR supplies these devices with +5V power.
Feedback devices must return a 5V--compatible output signal to the
control.
This feedback device can be used to provide:
auxiliary position feedback -- Digital systems require the
motor--mounted feedback device, provided on our standard digital servo
motors, be used for velocity--loop feedback. This motor--mounted
feedback device can also be used to close the position loop or an
additional auxiliary feedback device, as discussed in this section, can be
used for the position loop. You can not replace or bypass the
motor--mounted feedback device. The motor--mounted feedback device
must be used for velocity feedback and to attain proper motor
commutation on digital servo systems.
spindle feedback -- Provide position feedback for your spindle using
these high--resolution feedback device ports.
