Transmission speed setting (bit-rate)
The servo-motor is supplied with an initial bit-rate value of 500 Kbit/s.
If the value is not aligned with the one on the numerical control, it is necessary to follow the bit-rate
value setting procedure described below.
To set the required bit-rate value (DSW2), it is necessary to start the servo-motor with switch 6 On,
switch 5 Off and switches 1 to 4 set according to the bit-rate value required, as shown in the table
below.
Immediately after switch-on, the green servo-motor LED lights up for about 1 second. After this, if
the required bit-rate value has been successfully saved to the flash memory, it will start to flash
periodically with a number of blinks based on the bit-rate that has been selected.
If the dip-switch configuration is not one of those envisaged, the bit-rate value will remain as
before. If there are flash storage problems, the green LED will begin a 4-second flashing sequence
(2 seconds ON and 2 seconds OFF).
At the end of the procedure the servo-motor must be turned off and the dip-switch configuration
restored.
