Description
500 microseconds.
1 millisecond.
2 milliseconds.
(Visible when an absolute encoder is selected)
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 an absolute encoder is selected)
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 an absolute encoder is selected)
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 an absolute encoder is selected)
Selects the data format for an SSI encoder.
Binary code.
Gray code.
(Visible when an absolute encoder is selected)
Selects the baud rate for an SSI encoder.
10 kbit/s.
50 kbit/s.
100 kbit/s.
200 kbit/s.
500 kbit/s.
1000 kbit/s.
(Visible when an absolute encoder is selected)
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
Serial link mode).
315-45 degrees.
45-135 degrees.
135-225 degrees.
225-315 degrees.
(Visible when an absolute encoder is selected)
Defines the use of parity and stop bits with a HIPERFACE
encoder.
Typically this parameter need not be set.
Odd parity indication bit, one stop bit.
