The signal amplifier electronics (SVE) is used for encoders with current signals
between the encoder and drive module to convert the current signals into volta-
ge signals 1 Vpp .
The signal amplifier electronics were developed for optical encoder systems
equipped with photodiodes and no additional supplementary electronics (exam-
ple, ROD 456 from the Heidenhain company). However, there are many encod-
er systems in the market with integrated electronics where the behavior of cur-
rent signals is only roughly emulated. As a result of the many options available,
a general statement regarding the compatibility between the encoder, SVE and
closed–loop control cannot be made.
Notice
For new applications, no longer use encoders with current signals, as voltage
signals offer a higher noise immunity.
The signal amplification electronics can be used in conjunction with the
following control modules:
S
SIMODRIVE 611 digital High Standard or High Performance
S
SIMODRIVE 611 universal HRS/E HRS for encoders with sin/cos 1Vpp
S
HLA module
