SIMOLINK data interface
The SIMOLINK data interface comprises a single-channel SIMOLINK
receive data word; it does not provide a transmit channel. It expects the
speed setpoint for the frequency generator in receive channel 0 of the
set receive address. The setpoint is read in the MASTERDRIVES 32-bit
format (4000 0000 hex = 100 %); only the 10 highest bits are resolved,
corresponding to a speed resolution of 0.4 %.

The frequency generator has a frequency range of 0 Hz to 112 kHz (at
a rated frequency of 100 kHz). In the 90° pulses mode (4 edges
required for correct signal sequence from tracks A and B), the resulting
rated output frequency per track is 25 kHz and a maximum possible
setpoint output of approximately 112 %.

Relationship between setpoint and output frequency
When the setpoint exceeds 112 %, the SIMOLINK Pulse Generator
outputs the maximum frequency of approximately 28 kHz. If "100 kHz
signal“ mode is active, then approximately 112 kHz.
