Protocol overview

HIPERFACE DSL

® 

is a fast digital protocol for motor feedback systems for the connec‐

tion between servo drive and motor feedback system. The protocol is installed in the
transport layer in the frequency inverter using a digital logic circuit (DSL Master IP
Core).

The position data  are generated in two different ways in HIPERFACE DSL

®

, either in

free running mode, in which the position values are sampled and transmitted as quickly
as possible, or in SYNC mode, in which the position data are sampled and transmitted
synchronously  with a defined clock signal. With a frequency inverter application, this
clock signal is normally the clock feedback of the frequency inverter.

In SYNC mode the protocol matches the time points for the sampling of the data with‐
out time fluctuations with the clock coming from the frequency inverter.

For each frequency inverter cycle  at least one position value is sampled and transmit‐
ted with constant latency to the DSL Master. As the protocol matches the internal data
transfer speed to the frequency inverter cycle, the overall transfer rate of the
HIPERFACE DSL

® 

depends on the frequency inverter clock.

The protocol package  is matched to the various lengths, see 

figure 2

. Provided the fre‐

quency inverter cycle is long enough, additional sampling points can be positioned in
the frequency inverter cycle, known as "Extra" packages. The number of additional
packages is programmed by the user with a divider value.

The number of packages transmitted per frequency inverter cycle cannot be selected at
random, as the lower and upper range length of a protocol package must be adhered
to. This must be taken into account when setting the divider value.

In free running mode, the frequency inverter cycle is not taken into account for sam‐
pling and transmission and the protocol uses the minimum package length.

It must be noted that the minimum package length in free running mode is shorter than
the minimum package length in SYNC mode.

table 1

 shows the dependency of the lengths of the protocol packages using examples

for the length of the frequency inverter cycle.
