Valid for S700
Sine Encoder with SSI are a combination of Sine Encoder and SSI encoder for linear motion.
The encoders have a sine/cosine signal output for real time position measurement and a synchron serial signal for the absolute position.
S700 servo amplifiers can evaluate these encoders. You must set some parameters:
| FBTYPE =26 or 28 | SSI linear via X1 or X5 interface (PosI/O expansion card) |
| ENCLINES | Number of sine/cosine periods per motor pole pitch |
| SSIRESOL | Resolution of the digital SSI position (number of counts, which are delivered by the SSI encoder per sine period) |
Example:
SSI resolution 1µm, pole pitch distance 28 mm = 28000 µm
ENCLINES =1000
SSIRESOL =28
For the SSI communication these parameters are required:
ENCMODE =0
SSIRXD
SSIREVOL
SSITOUT
MPHASE determination: see page Setup of an Endat or Hiperface or BISS encoder for example.
Parameter overview see page Parameters for SSI Interface.
