Description
Selects the SSI encoder mode.
Note: This parameter needs to be set only when an SSI
encoder is used in continuous mode, i.e. without incremental
sin/cos signals (supported only as encoder 1). SSI encoder is
selected by setting parameter
Single position transfer mode (initial position).
Continuous position transfer mode.
Selects the transmission cycle for SSI encoder.
Note: This parameter needs to be set only when an SSI
encoder is used in continuous mode, i.e. without incremental
sin/cos signals (supported only as encoder 1). SSI encoder is
selected by setting parameter
50 µs transmission cycle.
100 µs transmission cycle.
200 µs transmission cycle.
500 µs transmission cycle.
1 ms transmission cycle.
2 ms transmission cycle.
Defines the phase angle within one sine/cosine signal period
that corresponds to the value of zero on the SSI serial link
data. The parameter is used to adjust the synchronization of
the SSI position data and the position based on sine/cosine
incremental signals. Incorrect synchronization may cause an
error of ±1 incremental period.
Note: This parameter needs only be set when an SSI
encoder with sine/cosine incremental signals is used in initial
position mode.
315...45° phase angle.
45...135° phase angle.
135...225° phase angle.
225...315° phase angle.
Selects the EnDat encoder mode.
Note: This parameter needs to be set only when an EnDat
encoder is used in continuous mode, i.e. without incremental
sin/cos signals (supported only as encoder 1). EnDat encoder
is selected by setting parameter
EnDat.
Single position data transfer (initial position).
Continuous position data transfer mode.
Selects the maximum encoder calculation time for EnDat
encoder.
Note: This parameter needs to be set only when an EnDat
encoder is used in continuous mode, i.e. without incremental
sin/cos signals (supported only as encoder 1). EnDat encoder
is selected by setting parameter
EnDat.
10 µs maximum calculation time.
100 µs maximum calculation time.
1 ms maximum calculation time.
50 ms maximum calculation time.
