OUTAN
Summary Sets speed reference.
Syntax OUTAN v
Parameter v = bus reference
range: –0X4000 – 0X4000 = –100 % – 100 %
Description The OUTAN command can set FC 300 bus reference (speed or torque reference
depending on setting of FC 300 par. 1-00).
With OUTAN it is also possible to turn off the controller in OPEN LOOP using MOTOR
OFF and to operate the FC 300 without feedback as a pure frequency converter. In
this manner you can use APOSS to directly output set values, to read inputs, etc.
NB!:
The command MOTOR OFF must be executed previously. Thus, monitoring of the
position error is no longer active.

Syntax Example MOTOR OFF /* turn off controller */
OUTAN 0X2000 /* set speed reference 50% */

OUTB
Summary Alteration of the condition of a digital output byte
Syntax OUTB n v
Parameter n = output byte
0 = 1 – 8
1 = 27,29
v = value (0 . . . 255)
Description With the OUTB command the condition of the digital outputs can be changed byte-
by-byte. The byte value transferred determines the condition of the individual
outputs. The bit with the lowest value in the byte corresponds to the set condition
of output 1.
NB!:
After switching on the system, all outputs are OFF. Outputs which have pre-defined
functions according to the I/O parameter settings will also be influenced by the
OUTB command! The actual output status remains as it is even after program end
or program aborted.
Output circuit and maximum load current see MCO Operating Instructions.
Command Group I/O
Cross Index OUT, IN, INB,
Parameters: 33-63...70 Terminal X59/n Digital Output , O_FUNCTION_n
Syntax Examples OUTB 0 10 // switch through outputs 2 and 4, disable other outputs
OUTB 0 245 // disable outputs 2 and 4, switch through all other outputs
OUTB 0 128 // switch through output 8 only, disable others
