Yaskawa serial encoders are not supported at this time. These serial encoders can only be tested using the corresponding Yaskawa drive SIGMA II series and higher. Motor part numbers that begin with 5 letters, the first 3 of which are ‘SGM’, all use serial encoders. Examples are SGMAH, SGMBH, SGMGH, SGMPH, SGMSH, SGMUH and SGMAS. Often there will be a part number on the encoder. If the encoder part number includes B13, B16 or B17 (13, 16 and 17 bit), then these are serial encoders. An example part number is UTSAE-B17BB. Part numbers including B12 and B15 are supported absolute encoders.
