d154
Constant surface speed control (Selector switch)
Related function codes:
d41 (Application control selection)
J01 PID control (Operation selection)
By using winding diameter calculation, constant surface (line speed) speed control can be performed even if the
roll winding diameter ratio changes significantly. If using winding diameter calculation, set d154 to 1.
• Data setting range: 0 to 1
Bit 0:
Winding diameter
compensation
0: Disable
(factory
default)
Disables winding diameter calculation, and runs the
inverter at the frequency setting from the host controller.
The frequency setting for which winding diameter
compensation was performed at the host controller is
used.
1: Enable
Enables winding diameter calculation, and runs the
inverter with the frequency command for which
compensation was performed with the winding diameter
calculated by the inverter. The line speed setting is used
for the inverter.
d158 to d166
Winding diameter calculation
Related function codes: d41 (Application control selection)
J01 PID control (Operation selection)
Calculates the roll winding diameter for constant surface speed control from the peripheral speed (line speed)
setting and roll rotation speed, compensates the output frequency even if the roll winding diameter changes, and
controls the speed so that the peripheral speed (line speed) remains constant when winding and unwinding.
Winding diameter calculation is valid only when PID control for dancer control is enabled (J01 = 3).
