2.6.25 SSI Feedback type.
SSITYPE
SSI feedback type connected to the corresponding feedback.
Possible values: Fagor SSITYPE / G user / User.
Default value: User.
Associated variable: (V.)[ch].MPA.SSITYPE[set].xn
When FEEDBACKTYPE=SSI, this parameter is used to set the format of the SSI
transmission. The parameter offers a number of preset types for connecting the most
common linear and rotary encoders. If the encoder is not listed, the user option may be
selected to set the properties of the SSI communication.
SSI
SSI (Synchronous Serial Interface) parameter table.
This parameter shows the parameter table to set the SSI transmission format. Depending
on the type of linear encoder selected, (parameter SSITYPE), some of these values will be
preset and cannot be changed. All values may be used for the "user" type linear encoder.

SSICLKFREQ = 1 / T = 400. 400 kHz.
SSIDATALENGTH = n Bit length of the position value (coordinate).
SSICRCBITS = 0 There are no CRC bits.
SSISTARTBITS = 0 There are no start bits.
SSIPACKFORMAT = 3 Data + Alarm.
SSIALARMBITS = 1 1 alarm/acknowledge bit.
SSIDATAMODE = 1 MSB First.
SSIALARMLEVEL = 1 The acknowledge is indicated with data at 0;
therefore, an alarm signal is produced when the bit is
at 1.
