Description
500 microseconds.
1 millisecond.
2 milliseconds.
(Visible when 92.1 Encoder 1 type
Defines the length of an SSI message. The length is
defined as the number of clock cycles. The number of
cycles can be calculated by adding 1 to the number of
bits in an SSI message frame.
SSI message length.
(Visible when 92.1 Encoder 1 type
With an SSI encoder, defines the location of the MSB
(most significant bit) of the position data within an SSI
message.
Position data MSB location (bit number).
(Visible when 92.1 Encoder 1 type
With an SSI encoder, defines the location of the MSB
(most significant bit) of the revolution count within an
SSI message.
Revolution count MSB location (bit number).
(Visible when 92.1 Encoder 1 type
Selects the data format for an SSI encoder.

Gray code.
(Visible when 92.1 Encoder 1 type
Selects the baud rate for an SSI encoder.

1000 kbit/s.
(Visible when 92.1 Encoder 1 type
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 to be set only when an SSI
encoder is used in initial position mode (see parameter
92.30 Serial link mode).
