Command Description - JVL FBG10 User Manual

4.2
The syntax for a command to a motor controller can be written:
Command
<command>
<value>
<sign>
<digits>
<cr>
Commands can be divided in three groups:
1. Commands which assign a register in the motor controller a new value.
2. Commands which perform control of a motor controller, for example 'RESET'.
3. Commands which request contents of a register or about a condition.
Ad 1. These commands always include <value>. Master on PROFIBUS must set the bit
C/Q = 1 as well as Format > 0 by sending this type of command. See section 3.6.1,
"Command Desciption", page 21 and section 3.6.2, "Format description", page 22.
Example:
Command
AC=123 <cr>
Ad 2. These commands leave out <value>. Master on PROFIBUS must set the bit C/Q =
1 and set Format = 0 by sending this type of command. See section 3.6.1, "Command De-
sciption", page 21 and section 3.6.2, "Format description", page 22. Example:
Command
SH <cr>
Ad 3. These commands leave out <value>. Master on PROFIBUS must set the bit C/Q =
0 and set Formatt = 0 .. 9 by sending this type of command. See section 3.6.1, "Command
Desciption", page 21 and section 3.6.2, "Format description", page 22. Example:
