Emotron AB 01-4429-01r2 Functional Description 63
Communication information
Encoder Feedback [22B]
Only visible if the Encoder option board is installed. This
parameter enables or disables the encoder feedback from the
motor to the VSD.
Communication information
Encoder Pulses [22C]
Only visible if the Encoder option board is installed. This
parameter describes the number of pulses per rotation for
your encoder, i.e. it is encoder specific. For more informa-
tion please see the encoder manual.
Communication information
Encoder Speed [22D]
Only visible if the Encoder option board is installed. This
parameter shows the measured motor speed. To check if the
encoder is correctly installed, set Encoder [23B] to Off, run
the VSD at any speed and compare with the value in this
menu. The value in this menu [22D] should be about the
same as the motor speed [712]. If you get the wrong sign for
the value, swap encoder input A and B.
Communication information
Default: Off, see Note
Off 0 Not active
Short 1
Parameters are measured with injected DC
current. No rotation of the shaft will occur.
Extended 2
Additional measurements, not possible to
perform with DC current, are done directly
after a short ID run. The shaft will rotate
and must be disconnected from the load.

WARNING: During the extended ID RUN, the
motor will rotate. Take safety measures to
avoid unforeseen dangerous situations.
NOTE: To run the VSD it is not mandatory for the ID RUN
to be executed, but without it the performance will not
be optimal.
NOTE: If the ID Run is aborted or not completed the
message “Interrupted!” will be displayed. The previous
data do not need to be changed in this case. Check that
the motor data are correct.
