Note
Manual control of output signals is only possible
when the M button and the manual mode increase
/decrease buttons are active (yellow LED's lit).
When only the M button is lit, the controller has
been forced to the manual mode externally, i.e.
with discrete switching signals or through the
RS-485 communications link.
Manual Output Signal Control (AOI)
Press the M button to select the manual mode. The yellow LED's in
the M button and the increase/decrease buttons light to indicate
Manual mode. The user can then change the output signal in 0.5
percent increments, using the yellow increase/decrease buttons.
To return to the Auto mode, simply press the M button again. The
yellow LED goes out, indicating Auto mode.
Output Signal Limiting (AOl)
To
prevent output signals on A01 from exceeding specified limits, set
upper and lower output signal limits, using FCODE 7 and 8. Select
output signal limiting using Fcode 105. Output signal limiting does not
apply to raise/lower outputs.

Forced Output Control (AOl)
With the exception of the raise/lower (positioning motor) outputs, the
controller's output signal A01 may be forced to a preset value by a
discrete input at Dll or Dl2.
Enable or disable the forced control function via FCODE 112.
