The SIMOLINK Pulse Generator updates the setpoint output in
response to every SYNC interrupt with which error-free data are
received. If a communications error occurs, the generator continues to
operate on the old setpoint. If CRC errors occur 8 times in succession,
it sets the frequency generator directly to 0 Hz and does not restart it
until an error-free setpoint is received. It switches to 0 Hz immediately if
communication on the SIMOLINK is aborted.
The frequency output of the SIMOLINK pulse generator in the 90°
pulses mode is identical to that of a pulse generator with 1000
pulses/rev and a speed normalization of 100 % = 1500 rev/min. If the
generator is to simulate shaft encoders with other pulse numbers per
revolution or different speed normalization, the setpoint to the SLP must
be renormalized. This can be done, for example, by multiplying the
machine setpoint. In this regard, it is important to note that the
maximum setpoint for the SLP on the SIMOLINK data interface must
not exceed 112 % (max. output frequency of approximately 28 kHz in
90° pulse mode).
