Winding diameter calculation (Moving average count)
Winding diameter calculation (Dead zone)
Related function code: d41 (Application control selection)
d158 Winding diameter calculation (Moving average count)
If there are fluctuations in the line speed setting or roll section detected speed, these can be smoothed with a
moving average filter. Set the moving average count in d158.
• Data setting range: 0 to 100 (times)
d159 (Winding diameter calculation (Dead zone)
If the difference between the roll section detected speed x winding diameter calculated value and the line speed
setting is low, the winding diameter calculation value can be held. Set the ratio to line speed setting as the dead
zone width in d159.
• Data setting range: 0.000 to 10.000(%)
Winding diameter (Calculation gain)
Related function code: d41 (Application control selection)
Calculates the roll winding diameter calculation to obtains the relationship roll section detected speed x winding
diameter calculation value = line speed setting.
The winding diameter calculation compensation time can be adjusted with the calculation gain. If the winding
diameter rate of change is low, and the winding diameter is small, set a small value for d160 if the detected speed
is easily affected, allowing the impact on the calculation to be minimized.
• Data setting range: 0.00 to 1.00
Winding diameter calculation (Compensation gain)
Related function code: d41 (Application control selection)
If there is an error between the actual machine and function code such as the reduction ratio set for the inverter, an
error will also occur in the winding diameter calculation. Adjust if compensating by setting the inverter winding
diameter calculation value to the same as the actual value.
• Data setting range: 0.000 to 10.000
Winding diameter calculation (Low-speed line speed ratio)
Related function code: d41 (Application control selection)
If the line speed setting is low, this holds the winding diameter calculation value to stabilize the motor speed.
Set the line speed for holding the winding diameter calculation value at the ratio to the maximum speed.
• Data setting range: 0.00 to 100.00(%)
