Table 6-1: Selection of tested encoders
6.1.2.5 Setting encoder type
Which encoder or which signals shall be evaluated is adjusted in ec16 encoder
type.
The identification and initialisation of the connected encoder is triggered by the
write access. This process can take upto several seconds.
If Endat encoders shall be evaluated at both channels, only Endat digital is possi-
ble at both channels.
If an error is displayed in ec00 status encoder interface it can be helpful for diag-
nostic purposes to set a different encoder type first, in order to check individual sig-
nals.
For example at a Hiperface encoder, only the evaluation of the 1Vss signals can be
activated with ec16 = 3 "sine/cosine without absolute track without zero signal".
By way it can be checked whether these signals are correctly connected and
whether the sense of rotation and the number of signal periods are correct.
Endat encoders with 1Vss signals can only be evaluated digitally. The serial com-
munication can be checked with it.
When switching between digital evaluation and evaluation with 1Vpp signals, the
position in the ru parameters changes slightly. There is a difference of half a signal
period because the digital position value is adapted to the 1Vpp signals.
The selection of an encoder type with or without zero signal means that the zero
signal is evaluated or not evaluated, independent whether the encoder actually
provides a zero signal.
