Dynamic series description
Frequencies

3.4 Frequencies
The radio link between the units of Autec Dynamic series radio remote controls
is built at one of the frequencies permitted by the European standards in force
when the system is put on the market.
Dynamic series industrial radio remote controls communicate either in dynamic
or static mode. Mode is set by the machine manufacturer.
3.4.1 Dynamic mode
A radio remote control communicating in dynamic mode:
- uses a working frequency in the band 863 - 870 MHz
- checks that the frequency is free before using it
- continually changes the working frequency to maintain the radio link even
when interference occurs.
3.4.2 Static mode
A radio remote control communicating in static mode:
- uses a working frequency in the band 869.7 - 870 MHz
- checks that the frequency is free before using it
- always works at the same frequency until the stop function is activated (see
paragraph 3.6.1).
3.5 Classification of commands
Commands sent by the transmitting unit are classified according to their type.
3.5.1 Command type: analogue, digital or direction command
Commands sent by the transmitting unit can either be analogue or digital.
Analogue commands generate proportional outputs as a function of the position
of the corresponding actuator.
Digital commands switch the status of their corresponding output, according to
the position of the related actuator. This status can either be on or off.
Direction commands are digital commands paired with analogue commands, and
are used to specify the movement direction.
3.5.2 Name of commands
All commands sent by the transmitting unit are identified by abbreviations, which
are also written in the technical data sheet to highlight the match between com-
mands sent and machine functions.
The names of outputs in the receiving unit are not the names of commands.
Check the technical data sheet to know which name they were given.
