CCW-R-2**B INSTRUCTION MANUAL 6 FUNCTIONS OF THE OPERATION SCREENS
6-109
6.13.3 AFD Range Setting
<Function>
This function sets the limitations in operation when the auto control is selected. When the auto control
function is highly responsive to significant external condition changes, the control may not work
properly. To prevent such a situation, the control operation can be limited with the AFD range setting.
However, bear in mind that the auto control may not work efficiently if the range is too small.
The control values apply to the parameters for auto control of each feeder described in “6.13.2 AFD
Ctroll Mode”.
1.RF
2.DF
• If the setting procedure is described in “6.13.2 AFD Ctroll Mode”, follow the descriptions.
• When the RF amplitude and DF amplitude is decreased, product infeed may stop even if the
amplitude is larger than 0 in some cases. Set the lower limit so that such a stop can be
prevented.
• Note that the DF operates continuously if the DF time is set to a value over the valid time
below.
[Valid DF time] = 3600 / (Weigher speed)
Table 6-50 AFD Range Setting List (RF)
Item Name Function
AMP upper limit, AMP lower
limit
RF amplitude is operated within the range between the set upper and lower limits
during auto control.
Time upper limit, Time lower
limit
RF time is operated within the range between the set upper and lower limits during
auto control.

Item Name Function
AMP DF amplitude is operated within the range between the set upper and lower limits
during auto control.
Time DF time is operated within the range between the set upper and lower limits during
auto control.
Weight [g] DF weight is operated within the range between the set upper and lower limits during
auto control.
AFD control stop DF weight
lower limit [%]
Limit of DF actual weight which stops automatic control. When the DF actual weight
is less than the set value, the auto control operation stops.
e.g.) If the DF target weight is set to 300g and the AFD control stop DF weight lower
limit is set to 60%, the auto control operation stops when the DF actual weight is less
than 120g.
