Machine parameters for the axes. Work sets.
FEEDBACK TYPE OF THE RCS-S MODULE.
FEEDBACKTYPE
Feedback type of the RCS-S module.
Possible values: TTL / differential TTL / Vpp / SSI.
Default value: Differential TTL.
Associated variable: (V.)[ch].MPA.FEEDBACKTYPE[set].xn
When the feedback input of the axis is located in an RCS-S module (Sercos counter), this
parameter sets the type of signal.
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.

ABSIND (inductosyn LIN+ABS) Absolute linear feedback.
ABSIND (inductosyn ROT+ABS) Absolute rotary feedback in one encoder revolution.
ABSIND (resolver) Absolute rotary feedback in one revolution.
ABSIND (inductosyn LIN) Absolute linear feedback in the pitch.

parameters (factory set).
SSICLOCKFRECUENCY = 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.
