Watchdog enable
bit 8
Watchdog function to be enabled; setting the
bit to “=0” causes the Watchdog function to be
disabled. When the Watchdog function is enabled, if the
device does not receive a message from the Server within 1
second, the system forces an alarm condition (the
alarm is invoked to appear as soon as the
Modbus network communication is restored). The Watchdog
function is a safety timer that uses a time-out to detect
loop or deadlock conditions. For instance, should the serial
communication be cut off while a command is still active
and running, the Watchdog safety system immediately
takes action and commands an alarm to be triggered.
Save parameters
bit 9
Data is saved on non-volatile memory at each rising edge of
the bit; in other words, data save is performed each time
this bit is switched from logic level low (“0”) to logic level
high (“1”).
Load default parameters
bit 10
Default parameters (they are set at the factory by Lika
Electronic engineers to allow the operator to run the device
for standard operation in a safe mode) are restored at each
rising edge of the bit; in other words, the default
parameters uploading operation is performed each time this
bit is switched from logic level low (“0”) to logic level high
(“1”). The complete list of machine data and relevant default
parameters preset by Lika Electronic engineers is available
on page 89.
WARNING
The execution of this command causes all parameters which
have been set previously to be overwritten!
Perform counting preset
bit 11
It allows to perform a homing operation of the encoder. As
soon as the command is sent, the position value which will
be transmitted for the current position of the encoder is the
one set next to the
and all the previous and following positions will get a value
according to it. Operation is performed at each rising edge
of the bit, i.e. each time this bit is switched from logic level
low (“0”) to logic level high (“1”). When this command is
