- / -Encoder 2 revolution count extension.-2147483648...2147483647
- / uint32Displays the raw measurement data of encoder 2
position (within one revolution) as a 24-bit unsigned
integer received from the encoder interface.
Note: This parameter is read-only.

- / uint32Displays the revolutions of (multiturn) encoder 2 within
its value range (see parameter 93.14 Revolution data
width) as a raw measurement.

is running, estimated position is used whenever
encoder feedback is unavailable. If the drive is in
stopped state, position counting will continue based
on encoder data after the connection is restored.)

Estimate / uint16Selects the motor speed feedback value used during
motor control.
Note: With a permanent magnet motor, make sure an
autophasing routine (see page 89) is performed using
the selected encoder. If necessary, set parameter 99.13
ID run requested to Autophasing to request a fresh
autophasing routine.
